PHP – How to check if variable is an array?

PHP has an internal variables handling functions to finds whether a variables is an array

is_array

<?php
if( is_array($elements) ){
	//do your work
}
?>

Another fastest way of determining an array is by:
Cast the value to an array, then check using (===) if it is identical to the original.

<?php
if ( (array) $elements!== $elements) { 
     echo '$elements is not an array'; 
 } else { 
     echo '$elements is an array'; 
 } 
?>
