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
Open a terminal and enter the following command:
php -i | grep php.ini
This will output the path to the php.ini file. For example, if your php.ini is located at /etc/php/7.4/cli/php.ini, the output might look like this:
Configuration File (php.ini) Path => /etc/php/7.4/cli Loaded Configuration File => /etc/php/7.4/cli/php.ini
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.
Method 2: Using the Web Server Management Interface
If the service you are running uses a web server (such as Apache or NGINX), you can use the Web Server Management Interface to find and edit the php.ini file . In the Apache HTTP server and NGINX, this can be achieved by adding the following directive in the web server configuration file:
Apache:
SetEnv PHPRC /path/to/php.ini
NGINX:
fastcgi_param PHP_VALUE "phprc=/path/to/php.ini";
in unofficial.php An unmaintained version of the php.ini file can be found on the .ini site.
Modify php.ini configuration
After you understand the location of the php.ini file, you can start modifying the configuration. The structure of the php.ini file is as follows:

In the php.ini file, comment lines begin with a semicolon (;). Instructions and values are separated by an equal sign (=).
