Here's a short explanation of the configuration directives.
assert.active
bool
Enable assert() evaluation.
assert.bail
bool
Terminate script execution on failed assertions.
assert.warning
bool
Issue a PHP warning for each failed assertion.
assert.callback
string
User function to call on failed assertions.
assert.quiet_eval
bool
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
bool
Issue an AssertionError exception for the failed assertion.
enable_dl
bool
This directive allows to turn dynamic loading of PHP extensions with dl() on and off.
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
int
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
.
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
int
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
int
Sets the max nesting depth of input variables (i.e. $_GET, $_POST.)
max_input_vars
int
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
bool
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
bool
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 magic_quotes_runtime
(does not include functions from PECL):
zend.enable_gc
bool
Enables or disables the circular reference collector.
