converting string into array with regex

How would you specify a regex to
convert string into array using preg_split?
Is there some symbol specyfying a place
between letters ?

s t r i n g => array('s', 't', 'r', 'i', 'n', 'g')
^ ^ ^ ^ ^

, like this...

You can access a string's characters with an index without declaring it
as an array.

$string = "foo";
echo $string{0}; //outputs f

http://www.php.net/substr (has an example)

Maybe this will solve your problem without using preg_split?

You kinda need to realize that

$String = 'FooBar';
print $String[4];

also prints out an 'B'. But this is adviced AGAINST because it is the same
syntax as you do for array elements.

To get a real array, do something like this:

$Array = Array();
for($i=0;$i<strlen($String);$i++) $Array[] = $String{$i};

But if you have a string with char-space-char stuff, split(' ', $String);
would do too.

No, no spaces between letters (otherways
it would be very easy, indeed). So there is
no way to match the "space between alphanumeric
chars" and split on it? I was trying to avoid
the loop solution.

Of course there is. In fact, this example, direct from the manual, does
exactly what you want...

<?php
$str = 'string';
$chars = preg_split('//', $str, -1, PREG_SPLIT_NO_EMPTY);
print_r($chars);
?>

LOL! :8]]

You are SO right. I just KNEW the
solution existed, I must have even read
it a long time ago in the very manual...
Sorry for wasting your precious time :8].
Thank you and all the others that tried
to help!
