1.2.1345. Use Variable Created Inside Loop¶
When a variable is created inside a loop, it should also be used in the loop. Otherwise, the variable will be overwritten by each loop, and become dead code.
<?php
foreach($a as $b => $c) {
$c = 1;
}
?>
1.2.1345.1. Suggestions¶
Remove the variable from the loop
Add usage to that variable inside the loop
Turn the variable into a property
