As of PHP 5 the error reporting constant E_STRICT is available, with the value 2048. When enabled, messages will be issued to warn you about code usage which is deprecated or which may not be future-proof.
Hinweis: E_ALL does not include E_STRICT, so it's not enabled by default. You must explicitly set the error reporting level to include E_STRICT in order to see these messages.
See Predefined Constants for more information.
To enable full error reporting (recommended for development boxes) use:
use error_reporting(E_ALL | E_STRICT);
or in php.ini:
error_reporting = E_ALL | E_STRICT
