For cPanel & WHM 54

(Home >> Service Configuration >> PHP Configuration Editor)


This interface allows you to configure your PHP settings. PHP is a scripting language that generates web pages.


cPanel users can view information about the server's PHP configuration in cPanel’s PHP interface (Home >> Software >> PHP).

PHP Configuration Editor

Select a tab below to view more information about that section of the PHP Configuration Editor interface.


Make your changes to the following directives and click Save.

Core asp_tags

Select whether PHP scripts can use ASP-like tags in addition to PHP tags.


This includes variable-value printing shorthand (for example, <%= $value %>) . 

Core  file_uploads Select whether your PHP scripts can upload HTTP files.On
Core include_path

Enter the paths in which PHP functions search for files when a script calls certain functions.


Separate the directory paths with a colon (:) in a *nix system, or a semicolon (;) in a Windows® environment.

Core memory_limit

Enter the maximum amount of memory that scripts can allocate, in bytes. This setting helps to prevent poorly-written scripts that may use too much memory. 


Use the character M to define the limit in Megabytes.

Core upload_max_filesize

Enter the maximum file size for an upload, in bytes.


Use the character M to define the limit in Megabytes.

Options & Information enable_dl

Select whether scripts can call the dl function. This function dynamically loads a PHP extension at runtime. 


If you set this directive to On, it poses security risks to your server. We strongly recommend that you select Off unless the dl function is absolutely necessary.

Options & Information max_execution_time Enter the maximum amount of time, in seconds, that your server allows a script to run before your server terminates it. This setting limits the amount of memory that poorly-written scripts may use.30
Options & Information max_input_time Enter the maximum amount of time, in seconds, that your server allows a script to parse input data.60
Options & Information max_input_vars Enter the maximum number of input variables per request. Use this directive to deter Denial of Service (DoS) attacks that use hash collisions on input variable names.1000
Session Handling session.save_path Enter the directory in which your server stores the files that PHP creates./tmp


Exercise extreme caution when you change any of these values; errors could result in non-functional PHP scripts. This section of the interface is for advanced users only.

The Advanced Mode section of this interface includes a large number of PHP directives. Make your changes to the desired directives and click Save.

For more information about a directive, search the php.net documentation.
