in_array() and multidimensional array

Question

I use in_array() to check whether a value exists in an array like below,

$a = array(\"Mac\", \"NT\", \"Irix\", \"Linux\");
if (in_array(\"Irix\"         


        

Answer 1

This will work too.

function in_array_r($item , $array){
    return preg_match('/"'.preg_quote($item, '/').'"/i' , json_encode($array));
}

Usage:

if(in_array_r($item , $array)){
    // found!
}
