1.2.278. Could Cast To Array

The array cast operator transform a scalar into an array with that scalar. It also keeps an array as an array, so a single call to (array) is able to convert scalars to array, while keeping values already in array form intact.

<?php

//
if (!is_array($a)) {
     $a = [$a];
}

// equivalent to
$a = (array) $a;

// same, with the else
if (is_array($a)) {
} else {
     $a = array($a);
}

?>
