1.2.891. Overwriting Variable¶
Replacing the content of a variable by something different is prone to errors. For example, it is not obvious if the $text variable is plain text or HTML text.
Besides, it is possible that the source is needed later, for extra processing.
Note that accumulators, like += .= or [] etc., that are meant to collect lots of values with consistent type are OK.
<?php
// Confusing
$text = htmlentities($text);
// Better
$textHTML = htmlentities($text);
?>
