You don't need sequential numbers as your key.
Take this example:
/*** define some values ***/
$fruits['apple']['color']=$color;
$fruits['apple']['diameter']=$x;
$fruits['orange']['color']=$color;
$fruits['orange']['diameter']=$x;
$fruits['grape']['color']=$color;
$fruits['grape']['diameter']=$x;
/*** Grab the keys ***/
$fruit_types = array_keys($fruits);
$count = 0;
while ($count < count($fruit_types))
{
$fruit = $fruit_types[$count];
$color = $fruits[$fruit]['color'];
$diameter = $fruits[$fruit]['diameter'];
}
