This is an overview of the recommended directives for your application. The most important directives have been collected here, for a quick review. The whole list of directive is available as a link to the manual, when applicable. When an extension is missing from the list below, either it as no specific configuration directive, or it is not used by the current code.
| Directive | Suggestion | Description |
|---|---|---|
| date | ||
| date.timezone | Europe/Amsterdam | It is not safe to rely on the system's timezone settings. Make sure the directive date.timezone is set in php.ini. |
| pcre | ||
| Extra configurations | PCRE runtime configuration | |
| standard | ||
| memory_limit | 120 | This sets the maximum amount of memory in bytes that a script is allowed to allocate. This helps prevent poorly written scripts for eating up all available memory on a server. It is recommended to set this as low as possible and avoid removing the limit. |
| max_execution_time | 90 | This sets the maximum amount of time, in seconds, that a script is allowed to run. The lower the value, the better for the server, but also, the better has the script to be written. Avoid really large values that are only useful for admin, and set them per directory. |
| expose_php | Off | Exposes to the world that PHP is installed on the server. For security reasons, it is better to keep this hidden. |
| display_errors | Off | This determines whether errors should be printed to the screen as part of the output or if they should be hidden from the user. |
| error_reporting | E_ALL | Set the error reporting level. Always set this high, so as to have the errors reported, and logged. |
| log_errors | On | Always log errors for future use |
| error_log | Name of a writable file, suitable for logging. | Name of the file where script errors should be logged. |
| Extra configurations | Standard runtime configuration | |
| Enable DL | ||
| enable_dl | Off | Whether or not to enable the dl() function. The dl() function does NOT work properly in multithreaded servers, such as IIS or Zeus, and is automatically disabled on them. |
| Error Log | ||
| error_log | On | Besides displaying errors, PHP can also log errors to locations such as a server-specific log, STDERR, or a location specified by the error_log directive |
| error_log | php_errors.log | Log errors to specified file. PHP's default behavior is to leave this value empty |
