1.2.1064. Self-Transforming Variables¶
Variables that are assigned to themselves, after transformation. Auto-transformations include appending element to an array, using post and pre increment operators, and assigning to the variable the result of a call where the variable is also an argument.
<?php
$s = strtolower($s);
// filtering one element AND dropping all that not 1
$a = array_filter('foo', $a[1]);
$o->m = foo($o->m);
?>
1.2.1064.1. Suggestions¶
Use new variables to hold transformed values.
