Question

I have this array:

$array = array(
    array('id' => 'test1', 
          'url' => 'test1url'
    ),

    array('id' => 'test2', 
          'url' => 'test2url'
    )
);

How to access “test1url” without knowing the parent key but knowing the corresponding ID (test1)?
If I knew the parent key I could simply access it like this:

$array[0]['url'];

So what would be the simplest/fastest/quickest/easiest way to access this value?

Thanks!

Answer 1

There is no solution better than looping all values in this case.

You can create a function like this:

function findUrl($array,$id) {
    foreach($array as $arr) {
        if($arr['id'] == $id) {
            return $arr['url'];
        }
    }
}

and call it:

echo findUrl($array,"test1");

or create another representation of your data, but if you cannot do it, the best solution is this loop.
