For further details and definitions of the PHP_INI_* modes, see the Where a configuration setting may be set. Here's a short explanation of the configuration directives.
assert.active
boolEnable assert() evaluation.
assert.bail
boolTerminate script execution on failed assertions.
assert.warning
boolIssue a PHP warning for each failed assertion.
assert.callback
stringUser function to call on failed assertions.
assert.quiet_eval
boolUse 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
boolIssue an AssertionError exception for the failed assertion.
enable_dl
boolThis 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.
max_execution_time
intThis 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 is0
.On non Windows systems, the maximum execution time is not affected by system calls, stream operations etc. Please see the set_time_limit() function for more details.
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
intThis 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 to0
to allow unlimited time.max_input_nesting_level
intSets the max nesting depth of input variables (i.e.
$_GET
,$_POST
.)max_input_vars
intHow 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
boolWarning
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.
See also get_magic_quotes_gpc()
magic_quotes_runtime
boolWarning
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.Functions affected by
