Description
The constant being accessed is not defined, which can result in a runtime warning on PHP < 8.0 and a fatal error on PHP >= 8.0.
Bad practice
$test = SOME_CONSTANT;
// invalid: constant "SOME_CONSTANT" is undefined
echo $test;
Recommended
Either define the constant, or remove the usage if it is not required:
define("SOME_CONSTANT", "Some value");
$test = SOME_CONSTANT;
echo $test;
