I'm looking for the equivalent of what in js would be 'this is a string'.split('') for PHP.
If I try $array = explode('', 'testing'); I get an error Warning: explode() [function.explode]: Empty delimiter in
Is there another way to do this?

As indicated by your error, explode requires a delimiter to split the string. Use str_split instead:
$arr = str_split('testing');
Output
Array
(
[0] => t
[1] => e
[2] => s
[3] => t
[4] => i
[5] => n
[6] => g
)

what about accents?
$string = "TEST";
echo $string[0]; // This will display T
There is no need to explode it

How would you create array from the string, each character as a separate element in the array?
Mark Roach
PHP looks at it as an array automatically if you treat it as one, and gives each character a key based on it's position.

Oh, really? See this: codepad.org/SRsULXQE ("Warning: array_map(): Argument #2 should be an array"). -1

He meant to say: "PHP will index a string like an array". But it is not an array and cannot be used on functions that require array inputs. However, you can loop over a string and extract an individual character with the same notation as an array with a
for loop over the strlen of the string.TO SPLIT string into ARRAY its best to use
$arr= str_split($string);
