Import a large SQL file in PHPMyAdmin

When wondering how to be able to import a larger SQL file in PHPMyAdmin, the solution is pretty easy, to allow it through the standard phpMyAdmin sql import - which can also be used to import a csv in phpMyAdmin, or even to import an OpenDocument Spreadsheet in phpMyAdmin, simply by changing the input format in import menu.

The limitation (for example, it can be 2Mb with XAMPP(Fig 1)) is most likely due to the php.ini configuration.

Simply open it - for example, with XAMPP, by selecting the Apache Config menu entry php.ini (Fig 2). Search for the following values in the php.ini file : post_max_size, upload_max_filesize, and memory_limit.

In case they are not in sync, the maximum allowed upload file size will be limited by the smaller value, keeping in mind the memory limit should be higher than the two other values, as memory will be needed to store and process the data, not counting other server activities.

These were the default values on my local server :

A possibility - to customize to specific needs - can be to update them to following values (Fig 3) :

Don't forget, after applying these changes, to restart the Apache server - on XAMPP, stop it (Fig 4) and start it again (Fig 5) (Fig 6) (Fig 7).

Just to show an example, in case only one value is updated, for example upload_max_filesize, it might end up with the following values (Fig 8) :

Even though the maximum filesize has been setup to a higher value, it won't work as the maximum posting size is lower.

PHPMyAdmin will only allow 8Mb in the later case.
