search a php array for partial string match

Question

I have an array and I\'d like to search for the string \'green\'. So in this case it should return the $arr[2]

$arr = array(0 =>         


        

Answer 1

function findStr($arr, $str) 
{  
    foreach ($arr as &$s) 
    {
       if(strpos($s, $str) !== false)
           return $s;
    }

    return "";
}

You can change the return value to the corresponding index number with a little modification if you want, but since you said "...return the $arr[2]" I wrote it to return the value instead.
