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.
Note:
E_ALL
does not includeE_STRICT
, so it's not enabled by default. You must explicitly set the error reporting level to includeE_STRICT
in order to see these messages.
See Predefined Constants for more information.
