1.2.380. Double Instructions¶
Twice the same call in a row. This might be a typo, and the second call is useless.
It may also be an non-idempotent method: that is, a method which has a different result when called with the same arguments. For example, rand() or fgets().
<?php
// repetition of the same command, with the same effect each time.
$a = array_merge($b, $c);
$a = array_merge($b, $c);
// false positive : commands are identical, but the effect is compounded
$a = array_merge($a, $c);
$a = array_merge($a, $c);
?>
