An Apache .htaccess file can be used to set specific configuration values for PHP in a website. This is a useful feature when looking for a temporary PHP setting specific to that website; for example when doing an upgrade.
To set a value use: _php_value _. Setting a boolean value is done using php_flag Off|On. An unlimited execution time can be set for example by placing php_value_time_limit 0 in the .htaccess file.
Overriding a PHP setting via .htaccess is not always allowed in the site configuration. To allow this the Options option must be added to the AllowOverride directive in the Virtualhost configuration of the site.
