Is_array ()

The PHP is_array () function is used to check whether a variable is an array. This function is especially used for security checks (such as form or SESSION checks ).

Syntax:

Bool is_array (mixed var) returns TRUE if var is array; otherwise, FALSE.

Example:

<? Php $ arr_age = array (18, 20, 25); if (is_array ($ arr_age) {echo 'variable $ arr_age is an array ';} else {echo 'variable $ arr_age is not an array';}?>

Run the sample output:

The variable $ arr_age is an array.
