The ini_set function in php is a function that comes with php to modify and set the php.ini configuration file. It is very convenient to use this function. There is no need to manually modify the php.ini file. Sometimes we do not have the permission to modify php. ini file, use this function at this time.

Syntax: ini_set("option", "value"); it is best to put this function at the top of the php script

For example: ini_set("max_execution_time", "180");//Set the php script timeout to 180 seconds

For specific php options, please refer to the Configuration PHP Core section of the phpinfo file

ini_get is just the opposite of ini_set, used to get the value of the environment variable in the php.ini file.

Syntax: string ini_get (string varname); Returns the value of the option, if the value of the option is a boolean, it returns 0 or 1

If you want to get the variable values ​​​​in the entire php.ini, we can use the enhanced function of ini_get ini_get_all(), which returns the entire php environment variables in the form of an array.
