php.ini or phprc

php.ini and .phprc are both configuration files used in PHP, but they are associated with different contexts and purposes.

1. php.ini:
   • Global Configuration: The php.ini file is the main configuration file for PHP and is used to configure the settings that apply globally to the PHP installation on a server.
   • System-wide Settings: Changes made in php.ini affect all PHP scripts running on the server, irrespective of the directory or user.
   • Server Level: It is typically located in a central location on the server and affects the entire PHP environment.
2. .phprc:
   • User-Specific Configuration: The .phprc file, on the other hand, is a user-specific configuration file that allows users to customize PHP settings for their specific needs.
   • Directory-Specific: The .phprc file is placed in the user’s home directory or in the directory of the script being executed. It allows for more localized and user-specific customization.
   • User Level: Changes in .phprc only affect the PHP scripts run by the user for whom the file is configured.

In summary, while php.ini is a global configuration file affecting the entire PHP environment on the server, .phprc provides a way for individual users to have their own PHP configurations, allowing for more fine-grained control at the user and directory level.

The concept of the .phprc file was introduced with the PHP 5.3.0 release. This file provides a way for users to have per-directory PHP configurations without the need for access to the global php.ini file. It allows users to set PHP configurations specifically for their directories or projects, providing more flexibility and granularity in configuration management.
