Iterating over a complex Associative Array in PHP

Question

Is there an easy way to iterate over an associative array of this structure in PHP:

The array $searches has a numbered index, with between 4 and 5 assoc

Answer 1

Looks like a good place for a recursive function, esp. if you'll have more than two levels of depth.

function doSomething(&$complex_array)
{
    foreach ($complex_array as $n => $v)
    {
        if (is_array($v))
            doSomething($v);
        else
            do whatever you want to do with a single node
    }
}
