To clear up a few thing:
Integers with 0 in front work. But since PHP (and many other languages) handle them as octal values,
they're only allowed a range of 0-7:
<?php
define('GOOD_OCTAL', 0700);
define('BAD_OCTAL', 0800);
print GOOD_OCTAL;
print '<br>';
print BAD_OCTAL;
?>
Result:
448
0
---------------------------------------
Furthermore,
writing the constant name without the quotation-marks (as mentioned in the notes) throws an E_NOTICE
and should be avoided!
<?php
define(TEST, 'Throws an E_NOTICE');
?>
Result:
Notice: Use of undefined constant TEST - assumed 'TEST'
