navigate multidimensional array with path in flat array

[Snaggy]

I have a big multidimensional array and I need to access it at various
levels. The path is stored in a flat array:

I'm doing it like this:

$path = array("people", "men", "tall")

$my_array = <---- this is the big array!

foreach ($path as $x) {$p .= "[\"".$x."\"]" ;}
$str = "$part = $my_array".$p;
eval($str);

which works but is very ugly, I'd like to do something like

$temp = $my_array[$path];

but it doesn't work of course.

What can I do?

thanks

something like:
function _get_from_array($array,$path){
$cur = $array;
while($key = array_shift($path)){
if(array_key_exists($cur,$pkey)){
$cur = $cur[$key];
} else {
trigger_error('array key doesn\'t exist');
return false;
}
}
return $cur;
}
$temp = _get_from_array($array,$path);
