1.2.568. Inconsistent Variable Usage¶
Those variables are used in various and inconsistent ways. It is difficult to understand if they are an array, an object or a scalar variable.
<?php
// $a is an array, then $b is a string.
$a = ['a', 'b', 'c'];
$b = implode('-', $a);
// $a is an array, then it is a string.
$a = ['a', 'b', 'c'];
$a = implode('-', $a);
?>
1.2.568.1. Suggestions¶
Keep one type for each variable. This keeps the code readable.
Give different names to variables with different types.
