1.2.984. Plus Plus Used On Strings¶
This rule reports strings that are incremented with the post increment operator 's'++.
This spots issues of the famous feature of PHP : incrementing strings with letters.
This analysis checks for string to be incremented. It doesn’t check if the string is a numeric string, but does check the type, implicit or explicit.
<?php
$a = 'a';
$a++;
print $a;
// prints b
?>
