This functions enable you to get a lot of information about PHP itself,
e.g. runtime configuration, loaded extensions, version and much more.
You'll also find functions to set options for your running PHP.
The probably best known function of PHP - phpinfo() -
can be found here.
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()
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
безопасный режим. In безопасный режим, it's
always impossible to use dl().
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.
The maximum execution time is not affected by system calls,
stream operations etc. Please see the
set_time_limit() function for more
details.
You can not change this setting with ini_set() when
running in безопасный режим. The only workaround is to turn off safe mode or
by changing the time limit in the php.ini.
Your webserver can have other timeouts. E.g. Apache has
Timeout directive, IIS has CGI timeout function, both
default to 300 seconds. See the webserver documentation for meaning of it.
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.
Замечание:
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.
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.
