1.2.170. Collect Compared Literals¶
This collects the different literals (null, integers, floats, strings) that are used in comparisons.
Comparisons include all the comparison operators : <, >, <=, >=, !=, <>, ==.
This analysis also covers switch(), array_keys() and in_array().
Strict searches are omitted. So, ===, !==, match(), in_array() and array_keys() with 3rd parameter are omitted.
Some comparisons are not covered yet : sort().
<?php
// Collects '>' and 3
if ($x > 3) {
// doSomething()
}
?>
