when casting or forcing a conversion from array to string, the result will be the word array.
$foo = 10; / / $foo is an integer $str = "$foo"; / / $str is a string $fst = (string) $foo; / / $fst is also a string / / this prints out that "they are the same "if ($fst === $str) {echo "they are the same";}
