1.2.83. Blind Variable Used Beyond Loop¶
Foreach() loops defines variables, which are traditionally used only inside the loop block. Using them beyond that limit often leads to surprises.
<?php
foreach($a as $b => $c) {
echo "$b : $c\n";
}
// $b is set inside the loop, but used beyond
$max = $b;
?>
