Can anyone tell me what the limit on number of dimensions for an array is?
As far as I know, there is no limit.
Of course, I have to wonder what the usable maximum is... heh. I can't imagine having a 100-dimension array... how boring to sit there and type
$myarray[1][4][5][8][3][10]['user']['password'][2][6][....
...of course, if you have $array[1][2]['three']['iv']['cinq']...
you can have $three=$array[1][2]['three']; and then say $three['iv']['cinq'];
But no, I've never found any practical limits (and the theoretical ones are off in the ozone anyway).
