MultiPHP INI Editor

Overview

This interface allows you to configure your PHP settings. 

Note:

WHM users can view information about the server's PHP INI settings in WHM’s MultiPHP INI Editor interface (WHM >> Home >> Software >> MultiPHP INI Editor).

MultiPHP INI Editor

Select the location that you wish to configure from the menu. You can edit either the account's home directory or the domain's document root. The PHP directives will appear.

Select a tab to view more information about that section of the MultiPHP INI Editor interface. 

The Basic Mode section of this interface loads directive values from the php.ini file for your selected domain or home directory. Make your changes to the desired directives and click Apply. The system saves changes to the php.ini file, the user.ini file, and your .htaccess file.

Notes:

  • For security purposes, we strongly recommend that you use the cPanel-provided default values.
  • The availability of directives depends on your version of PHP. If a directive does not appear in your interface, your version of PHP does not support it.
  • The system only writes a directive to an .ini or .htaccess file if that file supports the directive. Your php.ini.user.ini, and .htaccess files may not be identical. For more information about which files support which directives, read PHP's documentation.

Important:

If you use the DSO PHP handler and you change your PHP version to a different major PHP version, the system will not read your configuration changes. For example, if you change your PHP version from PHP 5 to PHP 7.

To correct this issue, you must edit and save your PHP configuration again in the interface. The system will then load the .htaccessdirectives correctly.

PHP directive
Description
cPanel default
PHP default
allow_url_fopen

Select whether PHP scripts can use URL-aware fopen wrappers.

Note:

The system only displays this directive if you use the suPHP PHP handler.

Disabled Enabled
allow_url_include

Select whether PHP scripts can use URL-aware fopen wrappers with the following functions:

  • include()
  • include_once()
  • require()
  • require_once()

Note:

The system only displays this directive if you use the suPHP PHP handler.

Disabled Disabled
asp_tags

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

Note:

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

Disabled Disabled
display_errors Select whether PHP displays errors as output or hides them from the user. Disabled Enabled
enable_dl

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

Warning:

If you set this directive to Enabled, it poses security risks to your server. We strongly recommend that you select Disabled unless you absolutely require the dlfunction.

Note:

The system only displays this directive if you use the suphp PHP handler.

Disabled Enabled
file_uploads

Select whether your PHP scripts can upload HTTP files.

Note:

The system only displays this directive if you use the suPHP PHP handler.

Enabled Enabled

magic_quotes_gpc

Select whether PHP automatically escapes certain characters with a backslash (\). Enabled Enabled
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 30
max_input_time Enter the maximum amount of time, in seconds, that your server allows a script to parse input data. 60 -1
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 1000
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. 

cPanel & WHM sets the default value based on the system's memory at the time of install.

Note:

Use the character M to define the limit in Megabytes.

cPanel & WHM adjusts this setting at the time of install, based on system memory:

  • 1 GB — 32M
  • 2-4GB — 64M
  • Over 4 GB — 128M
128M
post_max_size

Enter the maximum size of post data that the system allows, in bytes. This setting affects file uploads. Set this value to 0 to allow unlimited post sizes.

Notes:

  • We strongly recommend that you set this value larger than the upload_max_filesize value and smaller than the memory_limit value.
  • Use the character M to define the limit in Megabytes.
8M 8M

register_globals

Select whether GET or POST input converts into variables that the script can use. Disabled Disabled
