This article uses easy-to-understand examples to introduce where the php.ini configuration file of the virtual host is, the content is very detailed, interested friends can refer to it, I hope it can be helpful to you.

Virtual host php.ini files are typically placed in the "others" folder of the file manager. The php.ini file controls the performance and behavior of many aspects of PHP and must be named "php.ini".

A brief description of the PHP.ini file section configuration directive:

Short_open_tag boolean

Determines whether the abbreviated form of the PHP code start flag is allowed (). If you want to use PHP with XML, you can disable this option to facilitate embedding. Otherwise, you can also output through PHP, for example:. If disabled, you must use the full form of the PHP code start flag ().

Asp_tags boolean

In addition to the usual logos, ASP-style logos are allowed. This also includes an abbreviation for the value of the output variable.

Allow_call_time_pass_reference boolean

Whether to issue a warning when a parameter is passed by reference when a function is called. This approach is no longer approved and will probably no longer be supported in future versions of PHP/Zend. The encouraged method is to specify which parameters should be passed by reference in the function definition. People are encouraged to try to turn off this option and make sure that the script works properly to ensure that the script will also run in future versions (you will receive a warning each time you use this feature).

Passing parameters by reference during a function call is not recommended because it affects the cleanliness of the code. If the parameters of a function are not declared and passed as references, the function can modify its parameters by not writing to the document. To avoid its side effects, it is best to specify which parameter needs to be passed by reference only when the function is declared.

Disable_functions string

This directive allows you to disable certain functions for security reasons. Accepts a comma-separated list of function names as arguments. Disable_functions is not affected by security mode.
