PHP is a popular open source server-side scripting language that can be used to write dynamic web applications. Its flexibility makes it the choice for many web development projects. When developing web applications using PHP, you may need to make some modifications to PHP's configuration to meet your needs. One of the most common tasks is modifying the php.ini file.

php.ini is a text file containing PHP application configuration information. It is the main configuration file of the PHP interpreter. In many cases, modifying the php.ini file is necessary, such as increasing the memory limit available to PHP scripts. In this article, we will explore how to customize PHP's configuration by modifying the php.ini file.

Accessing the php.ini file

The php.ini file is usually located in the conf subfolder in the PHP installation folder. It can be accessed using the command line or web server management interface. Below are two different methods.

Method 1: Using the command line

php -i | grep php.ini
Copy after login

Configuration File (php.ini) Path => /etc/php/7.4/cli
Loaded Configuration File => /etc/php/7.4/cli/php.ini
Copy after login

In the above example, the value of "Loaded Configuration File" is The path to the php.ini file. You can open the file in the terminal using an editor such as nano or vi and edit it.

Apache:

SetEnv PHPRC /path/to/php.ini
Copy after login

NGINX:

fastcgi_param PHP_VALUE "phprc=/path/to/php.ini";
Copy after login
