PHP Php.ini file configuration

All parameters related to global variable registration, maximum upload size, displaying log errors, resource limits, maximum PHP script execution time, and others are written to a file as a set of directives that help declare changes. Note. Whenever any changes are made to the file, you need to restart our web server.This helps in simple administration of the web server using these configuration files. We can also write our own configuration files.Use the following program to check the file path: echo phpinfo(); ?> Note. Keys in file are case sensitive, keyword values ​​are not whitespace, and lines starting with semicolons are ignored. The file is well commented. Boolean values ​​are represented by incl. / Off, 1/0, True / False, Yes / No. The file contains a set of directives with a set of corresponding values ​​assigned to it. Values ​​can be a string, a number, a PHP constant, INI constants or an expression, a quoted string, or a reference to a previously set variable. An INI file expression is delimited by bitwise operators or parentheses. Settings with a specific hostname will only work on that specific host.File Environment Variables:
