Using PHP to backup MySQL databases


This post shows how to perform a partial or full backup of MySQL databases using only PHP code. This is very useful for example when a client doesn’t provide you with access data to the database of a web application and you only have an FTP connection available, or when you do have the connection data to the database but you can’t access it through the network (only available from localhost) and you can’t use tools like mysqldump to back up the information you need because you don’t have privileges for this, or simply because you have no access to a shell to which connect and run commands.

UPDATE (08-28-2017): moved the source code from myphp-backup.php and myphp-restore.php scripts to my GitHub daniloaz/myphp-backup repository

Backup of MySQL database tables

In any of the above scenarios, simply by copying and executing my myphp-backup.php PHP script as indicated below, you will be able to make a full or partial (only some tables) export of a database to a .sql or .sql.gz file that you will be able to download later from the same FTP account. The script includes the Backup_Database class that performs all the necessary operations and has different configuration options to control in which subdirectory you want the backup files to be stored and if you want them to be compressed with gzip or not. You’ll also need to establish the user credentials for accessing the database, as well as the name of that database:

 * Define database parameters here
define("DB_USER", 'your_username');
define("DB_PASSWORD", 'your_password');
define("DB_NAME", 'your_db_name');
define("DB_HOST", 'localhost');
define("BACKUP_DIR", 'myphp-backup-files'); // Comment this line to use same script's directory ('.')
define("TABLES", '*'); // Full backup
//define("TABLES", 'table1 table2 table3'); // Partial backup
define("CHARSET", 'utf8');
define("GZIP_BACKUP_FILE", true); // Set to false if you want plain SQL backup files (not gzipped)

PHP applications usually have a configuration file such as config.php or similar in which you probably can find database user and password if you don’t remember them or if your customer has not provided you with this information.

If you don’t have sufficient permissions to create the subdirectory where your backup files will be stored (by default myphp-backup-files/), you can use an existing directory. PHP applications usually have some subdirectory with enough permissions to create new files (cache, tmp, temp, etc.), which is where you will tell myphp-backup.php script to leave the file with the database backup. You can also use the root directory itself (DocumentRoot). To do this, simply assign a point (‘.’) to the BACKUP_DIR constant.

The .sql.gz or .sql file generated as a result of using the Backup_Database class of myphp-backup.php script will have a name with the following format (myphp-backup-{DB_NAME}-YYYYYYmmdd_HHHMMSS.sql.gz):

$ ls myphp-backup-files/*.sql.gz

Restoring tables from a MySQL database

The previous file will contain compressed (or not) SQL code ready to restore the structure and content of the original database in another database or in the same one but replacing the existing data with those of your backup file. To perform the restoration you will simply run the other script in my repository: myphp-restore.php. The only thing you will have to do to perform the restoration is to upload both the myphp-restore.php script and the backup file itself to a folder in which you have write permissions on the server where you want to import data and run it through your browser ( or from command line. Don’t forget to set backup file and folder names before using the BACKUP_FILE and BACKUP_DIR constants.

All the configuration options available for myphp-restore.php script are as follows:

 * Define database parameters here
define("DB_USER", 'your_username');
define("DB_PASSWORD", 'your_password');
define("DB_NAME", 'your_db_name');
define("DB_HOST", 'localhost');
define("BACKUP_DIR", 'myphp-backup-files'); // Comment this line to use same script's directory ('.')
define("BACKUP_FILE", 'your-backup-file.sql.gz'); // Script will autodetect if backup file is gzipped or not based on .gz extension
define("CHARSET", 'utf8');

The script will automatically detect whether the backup file is compressed with gzip or not based on the .gz extension, so you don’t have to make any additional settings for this.

                    Hi Daniel,
                    thanks for the excellent work. Saving the database is very useful. I tried the class on different databases and it works great. Only on a OpenCart db returns errors for only 3 tables: OPTION, ORDER and RETURN

                    this is the error

                    Backing up return table…
                    Warning: mysql_num_fields(): supplied argument is not a valid MySQL result resource in /home/………………/run.php on line 119

                    Warning: mysql_fetch_row(): supplied argument is not a valid MySQL result resource in /home/………………/run.php on line 122

                    I can not understand why!

                    Hi George,

                    Thanks for the feedback. I think that the three tables you mentioned have some kind of corruption, and that’s why you get those warning messages. I got the same results when I tried to backup a database with corrupted tables:

                    Backing up livehelp_transcripts table… OK
                    Backing up livehelp_users table… OK
                    Backing up livehelp_visit_track table… OK
                    Backing up livehelp_visits_daily table…
                    Warning: mysql_num_fields(): supplied argument is not a valid MySQL result resource in /var/www/vhosts/ on line 119

                    Warning: mysql_fetch_row(): supplied argument is not a valid MySQL result resource in /var/www/vhosts/ on line 122

                    As you can see next, the failing livehelp_visits_daily table is corrupted:

                    mysql> CHECK TABLE livehelp_visits_daily FAST QUICK;
                    | Table | Op | Msg | Msg_text |
                    | crafty.livehelp_visits_daily | check | warn | Table is marked as crashed |
                    | crafty.livehelp_visits_daily | check | error | Size of indexfile is: 892928
                    Should be: 897024 |

                    Hi Daniloaz,
                    is true, in fact I checked the tables and had a few problems. Thank you!

                    George_p - 27/03/2012 reply

                    Hi daniloaz, I double checked again and i must say that the error occurred
                    However I solved it.
                    The problem occurs only on a server where I run the script.
                    To fix I added this symbol “`” before and after the name of all code contain

                    For exemple:
                    $result = mysql_query(‘SELECT * FROM `’.$table.’`’);
                    $numFields = mysql_num_fields($result) or die(mysql_error());

                    I hope can help someone who has had the same problem!

                    Daniel - 12/06/2012 reply

                    Yes, it’s true. When a table name matches an internal command of MySQL, the script fails to export that table. This is solved as you say adding ` and ` before and after the name of the table. Thank you very much for your clarification!

                    Daniel - 07/08/2012 reply

                    ereg_replace() function is deprectaded in PHP 5.3. Sorry, I should update the script. In the mean time, you can avoid this problem just replacing calls to ereg_replace() function with preg_replace(), wich have the same syntax than ereg_replace and works properly in PHP 5.3.

                    Burhan Ibrahimi - 24/03/2015 reply

                    the preg_replace functions is not working everything is blank and not fild in backup file..

                    have you the script for restore ?

                    Daniel - 07/08/2012 reply

                    No, sorry, but you can restore using the command line like this:

                    $ mysql -u db_user -p db_name < db-backup-db_name-20120807111744.sql db-backup-db_name-20120807111744.sql is the resulting file from the above script excution.

                    I could not get a direct substitution of ereg_replace by preg_replace to work. The data
                    was just replaced with a null. Nor could I find any easy help in the manuals. Life is too
                    short so change the error reporting to:
                    error_reporting (E_ALL ^ E_DEPRECATED);

                    Great script, but when I was backing up my Magento DB it seems to be “sort of a timed out”. After a couple tries it gets “stuck” without any error report on the table “report_event”. On small databases the script works great, but do you have any tips how I can let the session last longer so it can finish the whole DB backup?

                  • Anthony - 19/11/2013 reply

                    Perfectly made script – but it fails with big databases (with tables over 10k rows). Needs adaptation useing data splitting to chunks for both MySQL queries (… LIMIT , ) and file writing – otherwise you will get either “<ySQL client is out of memory" or null-sized dump files.

                    It worked perfect for 2 wordpress sites and one joomla.
                    But in 2 opencart sites, when I try to restore the database to a new one I get this error:

                    DROP TABLE IF EXISTS OPTION ;
                    #1064 – You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘option’ at line 1

                    Any idea why?

                    Daniel - 06/02/2014 reply

                    Thanks! But the script is still far from perfect. In fact, the problem you mentioned is due to script’s wrong interpretation of the reserved word OPTION, wich is the same name you used for your table. Use an alternative name for your table (using a custom prefix is always a good idea), or quote the table name. Hope this helps!

                    Try to put slashes before and after the regular expression, as preg_replace() function requires them. Write something like preg_replace(“/n/”,”\n”,$row[$j]);

                    This script is only able to perform backups generating a SQL file wich you can restore via mysql command, but you can’t restore it via PHP. You would have to make major changes to the script to achieve it. Sorry, it’s a pending task…

                    Thanks for the script, just what i’ve been looking for!
                    I’ve executed the PHP script and got the “Backup result: OK” message but i cant find the resulting SQL file? Where would I need to look for it?
                    Thanks again,

                    Backup destination is set using the OUTPUT_DIR constant defined at the the beginning of the script. In my case I set the cache directory, but this directory does’t have to exist in all installations where you run the script. Therefore, you should define a directory that is valid in your particular case, or not directory at all and let the script to save the file in your webroot directory.

                    Hello Daniel,
                    very Nice script for database backup.
                    but my table in 48698 records that time this script can’t take backup.
                    There is display message like this “Backing up tags table… OK Backing up third_party_review table… OK Backing up third_party_review_data table…”

                    third_party_review_data table in 48698 records therefor can’t take backup.
                    any suggestion for get big database table backup.

                    This script replaces NULL with “”. So my NULL date values were getting imported as 0000-00-00 because they were the wrong format. To fix this, simply add an if/else for NULL:

                    if (isset($row[$j]))
                    if($row[$j]!=NULL) {
                    $sql .= “‘”.$row[$j].”‘” ;
                    else {
                    $sql .= “NULL” ;

                    Note how the NULL is not in quotes. (I’ve also changed the double quotes to single too)

                    Also, for some reason, I have changed the * to a specific table name, yet it somehow export all tables in the database. I can’t see why this happens?

                    it doesn`t take the values from table :
                    INSERT INTO language VALUES(“”,””,””,””,””,””,””);
                    this is a part from saved SQL file

                    Hi! Thanks for posting this. I tried this script and did some modification because I’m using mysqli.
                    I can now have the sql backup file but when I open it, the values in every table are all “0”.
                    (e.g. INSERT INTO info VALUES(“0″,”0″,”0″,”0″,”0″,”0″,”0″,”0″,”0″,”0″,”0″,”0″,”0″,”0″,”0″,”0″,”0″,”0″,”0″,”0″,”0″,”0″,”0”); ) How am I going to fix it? Hoping for you assistance. Thanks.

                    I have changed the ereg_replace function with preg_replace but its not goes fine.
                    It gives error like
                    Warning: preg_replace(): Empty regular expression
                    Help me to make this happen.

                    Mariana - 11/08/2015 reply

                    You can use str_replace, instead:
                    $row[$j] = str_replace( array(“rn”, “r”, “n”) , ‘\r\n’ , $row[$j] );

                    * Note that I used double-quotes on first argument, and single-quotes on the second, because I want it on a string on the .sql code. Otherwise, they will be interpreted by PHP. (You may use double-quotes if you want). I also included other options, ’cause some servers uses rn

So for the sake of backup/restore mysql data from PHP i have made a program that can compress the data into a zip file that you can download. Later you can upload and restore full database. You can find it in my Github page

                    Hello Daniel (Sir),
                    i want to take back up (export) tables from the database in local system(it should ask where to store these files) or the path (another drive). And in case of import the table it should take files from local drive or which i have to choose. I am using CentOS. So, please let me know, how to do this….

                    Daniel - 02/08/2018 reply

                    You only have to set the BACKUP_DIR constant at the beginning of either the backup or restore script with the proper directory where you want the backup files to be created or read.

                    Awesome script, but I have one small issue. When I run it I get this error: ob_flush(): failed to flush buffer. No buffer to flush in /home… on line 364

                    The error does not affect the script running or generating the backups, so this might be a false positive! Is it something I can fix on my own!?

                    Daniel - 27/10/2018 reply

                    Thanks Seul, I added a check before performing ob_flush() to prevent “ob_flush(): failed to flush buffer. No buffer to flush.” errors. I think you shouldn’t have that problem again.

                    Is this possible to use all codes within a single function??
                    I just want to merge backup and restore files in a sinle file .
                    Problem I’m facing is I’m unable to call a function for post method ( I’m using manual inputs) .
                    Can you clarify me this ?

                    You have to upload both the restoration script and the SQL file to the remote server via FTP or similar, and then run the first one pointing to using your browser.

                    Excellent! I cannot thank you enough. However, is there a way to manipulate the script in such a way that all “VIEWS” do not have INSERT INTO … just the way phpMyAdmin would’ve done it? The CREATE ALGORITHM should be there.
