How to Override PHP Settings
Sometimes you want to use software inside your Magento shop, that require some other settings for PHP then the defaults supply. For example changing the max_execution_time
for a PHP script in a certain directory.
What Settings Can Be Overridden
Some examples of settings you might want to override are:
upload_max_filesize
post_max_size
max_execution_time
PHP uses several modes to adjust settings. These modes determine when and where a PHP setting can be set or changed and by who.
For example, some settings may be set within a PHP script using ini_set()
, whereas others that may only be changed by server administrators are set in the php.ini
file in /etc/php
.
Every PHP setting has it’s own mode and thus a place to configure. If a setting can be set in a .user.ini
, you have the ability to change or adjust this setting yourself manually by adding it to .user.ini
in a specific directory.
Mode |
Meaning |
---|---|
PHP_INI_ALL |
This entry can be set anywhere |
PHP_INI_USER |
This entry can be set in user scripts (with |
PHP_INI_PERDIR |
This entry can be set in |
PHP_INI_SYSTEM |
This entry can only be changed by us. Please contact support. |
The PHP_INI_SYSTEM
settings can’t be changed easily: We chose those values carefully to ensure stability and the most performant settings possible.
Entries in .user.ini
Are Recursive
With a few easy steps, you can override php settings when running in PHP-FPM mode. PHP not only loads the php.ini
file itself, but it also scans for INI files in each directory; First in the directory the executed script is loaded in, and keeps looking in higher up directories until it reaches the ~/public/
directory.
Please note: This would mean, for example, if you were to create the .user.ini within the ~/public/dir1/
directory, the changes are applied to the PHP scripts that are installed in that particular directory only.
Any subsequent PHP installations such as WordPress in a ~/public/blog/
directory, will not be affected by the changes in this .user.ini
If you wish to change the settings for both directories, you’ll have to install two separate .user.ini
files, or place the .user.ini
file in your ~/public/
directory. This will affect all PHP scripts running on your Hypernode.
More info can be found on thePHP documentation page.
Changing your PHP settings
In this example we’ll show you how to increase the max_execution_time
in PHP. If you’ve created a .user.ini
file in the right directory, all you need to do is open up your .user.ini
file and add the following line:
max_execution_time = 3600
Keep in mind:
PHP Settings in
.user.ini
files are cached by PHP-FPM. When changing settings has no effect, try restarting the PHP-FPM workers:pkill -u app php-fpm
The memory_limit settings are hardcoded and thus cannot be overridden.
