    Here’s a short explanation of the configuration
    directives. boolean

    Enable assert()


    Terminate script execution on failed

    assert.warning boolean

    Issue a PHP warning for each failed assertion.

    assert.callback string

    User function to call on failed assertions.

    assert.quiet_eval boolean

    Use the current setting of error_reporting() during assertion expression
    evaluation. If enabled, no errors are shown (implicit
    error_reporting(0)) while evaluation. If disabled, errors are shown
    according to the settings of error_reporting()

    assert.exception boolean

    Issue an AssertionError exception for the failed


    This directive is really only useful in the Apache
    module version of PHP. You can turn dynamic loading of PHP
    extensions with dl() on and off per virtual server or
    per directory.

    The main reason for turning dynamic loading off is
    security. With dynamic loading, it’s possible to ignore all
    open_basedir restrictions. The default is to allow
    dynamic loading, except when using safe mode.
    In safe mode, it’s always impossible to use dl().

    max_execution_time integer

    This sets the maximum time in seconds a script is
    allowed to run before it is terminated by the parser. This helps
    prevent poorly written scripts from tying up the server. The
    default setting is 30. When running PHP from the command line the
    default setting is 0.

    The maximum execution time is not affected by
    system calls, stream operations etc. Please see the set_time_limit() function for more

    You can not change this setting with ini_set() when running in safe mode.
    The only workaround is to turn off safe mode or by changing the
    time limit in the php.ini.

    Your web server can have other timeout
    configurations that may also interrupt PHP execution. Apache has a
    Timeout directive and IIS has a CGI timeout function. Both
    default to 300 seconds. See your web server documentation for
    specific details.

    max_input_time integer

    This sets the maximum time in seconds a script is
    allowed to parse input data, like POST and GET. Timing begins at
    the moment PHP is invoked at the server and ends when execution
    begins. The default setting is -1, which means that
    max_execution_time is used instead. Set to 0 to
    allow unlimited time.

    max_input_nesting_level integer

    Sets the max nesting depth of input variables
    (i.e. $_GET, $_POST.)

    max_input_vars integer

    How many input variables may be accepted (limit is applied
    to $_GET, $_POST and $_COOKIE superglobal separately). Use of this
    directive mitigates the possibility of denial of service attacks
    which use hash collisions. If there are more input variables than
    specified by this directive, an
    E_WARNING is issued, and further
    input variables are truncated from the request.

    magic_quotes_gpc boolean

    This feature has been DEPRECATED as of PHP 5.3.0 and REMOVED as of PHP 5.4.0.

    Sets the magic_quotes state for GPC
    (Get/Post/Cookie) operations. When magic_quotes are on, all ‘
    (single-quote), ” (double quote), \ (backslash) and NUL’s are
    escaped with a backslash automatically.


    If the magic_quotes_sybase directive is also ON it will
    completely override magic_quotes_gpc. Having both directives
    enabled means only single quotes are escaped as . Double quotes, backslashes and NUL’s will
    remain untouched and unescaped.

    See also get_magic_quotes_gpc()

    magic_quotes_runtime boolean

    This feature has been DEPRECATED as of PHP 5.3.0 and REMOVED as of PHP 5.4.0.

    If magic_quotes_runtime is enabled, most functions
    that return data from any sort of external source including
    databases and text files will have quotes escaped with a backslash.
    If magic_quotes_sybase is also on, a single-quote is
    escaped with a single-quote instead of a backslash.

    Functions affected by magic_quotes_runtime (does not include functions
    from PECL):

    zend.enable_gc boolean

    Enables or disables the circular reference
