1.2.1244. Undefined Constants¶
Constants definition can’t be located.
Those constants are not defined in the code, and will raise errors, or use the fallback mechanism of being treated like a string. It is recommended to define them all, or to avoid using them.
<?php
const A = 1;
define('B', 2);
// here, C is not defined in the code and is reported
echo A.B.C;
?>
See also Constants.
