WordPress is a popular blogging and website content management system, but it can be difficult to find the PHP.ini file if you need to edit some settings. This answer will tell you where to find this important configuration file so that you can make changes as needed!
The PHP.ini file is a configuration file that stores various settings for your server and the WordPress application, such as memory limit and session timeouts. It can be found in different locations depending on how you installed it.
WordPress Installed via Package:
If you installed WordPress using a package, or if your host runs PHP through a Windows service such as WAMP, XAMPP, etc., the PHP.ini file is located in a different place than if you installed WordPress manually through FTP. The file is either located in:
/path-to-your-installation/wp-includes or /usr/local/lib (or /usr/local/apache or wherever your PHP install is)
WordPress Installed Manually via FTP:
If you installed WordPress manually through FTP, the PHP.ini file will be in your WordPress directory (the same place you put wp-config.php). The default location is:
/wp-config.php or /public_html/blog
The file may be named php.ini, but the standard WordPress naming convention is to name it php.ini-development or php.ini-production depending on the server environment (this way you can have two different php.ini files).
An important thing to note is that the file may either be called php.ini or php.ini-development (or -production). If you can’t find the file, it may be because your host is looking in a different location than expected.
