How to set memory size in php

How to set the memory size in php?

When running a PHP program, you usually encounter the error "Fatal Error: Allowed memory size of xxxxxx bytes exhausted". This means that the PHP script uses too much memory and exceeds the system limit. It sets the maximum memory allowed. To solve this problem, you first need to check whether your program has allocated too much memory. If there are no problems with the program, you can increase PHP's memory limit (memory_limit) through the following methods.

Check the memory limit value of php

In order to view this value, you need to create an empty php file, such as view-php-info .php. Then paste the following code inside.

<?php phpinfo(); ?>

Put this script on your PHP host and call it in the browser. At this time you can see the information about your PHP environment configuration, part of which is about "memory_limit", as shown below:

Note: You can use this method Let’s check other parameter settings of php, not just memory_limit

How much should memory_limit be set to?

This completely depends on the requirements of your application. For example, WordPress requires 32MB to run the core code. Drupal 6 requires this value to be at least 16MB, and recommends setting it to 32MB. If you install a lot of plug-ins, especially those that require image processing, you may need 128MB or more memory.

How to set memory_limit

The simplest or most common method is to modify php.ini

First find the php that is effective for your website .iniFile

Since there are multiple places where you can set php parameters, finding the correct configuration file and making changes is the first step. If you created a php file using the above method to view its configuration parameters, you can find the "Loaded Configuration File" item. The following is an example:

For Linux users, you can Find the corresponding configuration file by executing "php -i | grep Loaded Configuration File". For Windows users, you can try modifying php.ini in your php installation directory.

Editphp.ini

In php.ini, find the item "memory_limit", if not , you can add this parameter yourself at the end of the file. The following are some setting examples

memory_limit = 128M; You can change 128M to any value you want to set

Save the file

Restart web server

If the web server uses Apache, execute:

httpd restart

In some cases, you may not be allowed to modify php.ini privately. For example, if you purchased a virtual hosting service, but your service provider does not allow you to modify this file. Then, you may need to consider other methods to increase the value of memory_limit.
