Can a flat array of strings be considered a "Multidimensional String Array"?

Question

Given an array of $a = array("Hello","World") and $a[0] holds Hello and $a[0][0] holds value H, is it correct to say that $a is a "Multidimensional String Array"?

And $a[0][0][0][0][0] is still H. And $a[0]['foo']['bar'] is still H (on < 5.4). Just because it looks like an array, doesn't mean it is one... — ircmaxell

No, $a is a 1-dimensional array. Period.

Although strings can be accessed/modified by character using index notation, and are implemented internally as character sequences, PHP strings are not true PHP arrays.

Is it correct to say that $a is now a Multidimensional String Array?

Ask your PHP:

foreach($a[0] as $char);

and see what does it say.

Invalid argument supplied for foreach(), so it's not an array.
