help with multi dem array in_array

i am using this to test multi dem arrays
function in_array_multidem($array, $val){
    if(!is_array($array)){
        return false;
    }

    if(in_array($val, $array)){
        return true;
    }

    foreach($array as $row){
        if(array_multi_search($val, $array )){
            return true;
        }
    }
    return false;
}


but i want to change it slightly. i would like to supply an additional parameter to restict it to a named array value.
in the array below i would like to test if [foo] = apple (which should return false) but right now it will return true because technically apple is in_array

Array
(
    [0] => Array
        (
            [foo] => orange
            [bar] => apple
        )
)

Hi qwertq,

Well, you can check if it isset, if it is, then check its value.

foreach($array as $row)
{
    if (isset($row['foo']))
    {
        if ($row['foo'] == 'apple')
          return true;
    }
}
return false;

How about that?

thanks, that worked.

here is my updated function for future reference

function in_array_multidem($array, $val, $node = false){

    if(!is_array($array)){
        return false;
    }

    if(in_array($val, $array)){
        return true;
    }
   
    foreach($array as $row){
       
        if ($node && isset($row[$node])){
            if ($row[$node] == $val){
                return true;
            }
        }
           
        if(array_multi_search($val, $array )){
            return true;
        }
    }
    return false;
}
