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 associative parts. So I not only need to iterate over $searches[0] through $searches[n], but also $searches[0]["part0"] through $searches[n]["partn"]. The hard part is that different indexes have different numbers of parts (some might be missing one or two).

Thoughts on doing this in a way that's nice, neat, and understandable?

Answer 1

Nest two foreach loops:

foreach ($array as $i => $values) {
    print "$i {\n";
    foreach ($values as $key => $value) {
        print "    $key => $value\n";
    }
    print "}\n";
}

Answer 2

I know it's question necromancy, but iterating over Multidimensional arrays is easy with Spl Iterators

$iterator = new RecursiveIteratorIterator(new RecursiveArrayIterator($array));

foreach($iterator as $key=>$value) {
    echo $key.' -- '.$value.'<br />';
}
