Changes to INI file handling
PHP 5.3.0 has significantly improved performance and parsing of INI files,
and adds several new syntax features.
-
The standard php.ini files have been re-organized and renamed.
php.ini-development contains settings recommded
for use in development environments. php.ini-production
contains settings recommended for use in production environments.
-
There is now support for two special sections:
[PATH=/opt/httpd/www.example.com/] and
[HOST=www.example.com]. Directives set in these
sections cannot be overridden by user-defined INI files or at
runtime. More information about these sections can be found
here.
-
zend_extension_debug,
zend_extension_debug_ts
and zend_extension_ts have
been removed. Use the
zend_extension directive to
load all Zend Extensions.
-
zend.ze1_compatibility_mode
has been removed. If this INI directive is set to On, an
E_ERROR error is emitted at startup.
-
It is now possible to use the full path to load modules using the
extension directive.
-
"ini-variables" can now be used almost anywhere in a
php.ini file.
-
open_basedir restrictions may now
be tighted at runtime, and the directive is now PHP_INI_ALL.
-
It is now possible to use alphanumeric or variable indices in INI option
arrays.
-
get_cfg_var() is now able to return "array" INI options.
-
Two new mail directives:
mail.add_x_header and
mail.log, have been added.
The following new ini directives have been added:
-
user_ini.filename and
user_ini.cache_ttl have been added to control the use
of user INI files.
-
exit_on_timeout has been added
to force Apache 1.x children to exit if a PHP execution timeout occurs.
-
Added mbstring.http_output_conv_mimetype.
This directive specifies the regex pattern of content types for which
mb_output_handler() is activated.
-
Added request_order.
Allows controlling which external variables will be available in
$_REQUEST.
The following ini directives have new default values:
