1.2.1422. Variables With One Letter Names¶
Variables with one letter name are the shortest name for variables. They also bear very little meaning : what does contain the variable
$w?
Some one-letter variables have meaning : $x and $y for coordinates, $i, $j, $k for blind variables. Others tend to be an easy way to give a name to a variable, without thinking too hard a good name.
<?php
// $a is reported as a one-letter variable
$a = 0;
// $i is considered a false positive.
for($i = 0; $i < 10; ++$i) {
$a += doSomething($i);
}
?>
