PHP: How to ensure a variable is an Array, and it is not empty

is_empty_array.php

<?php

// returns True if the given $var is an Array, and it is not empty;
// otherwise, False.  It does not gives an error if the given $var
// is not an Array, however, it returns False.
function isNonEmptyArray($var) {
    return !empty(@reset($var));
}

This is basically a shorthand for:

is_array($var) && !empty($var)
