PHP: Split string into array, like explode with no delimiter

oni-kun picture oni-kun · Jan 31, 2010 · Viewed 118.1k times · Source

I have a string such as:

"0123456789"

and need to split EACH character into an array.

I for the hell of it tried:

explode('', '123545789');

But it gave me the obvious: Warning: No delimiter defined in explode) ..

How would I come across this? I can't see any method off hand, especially just a function

$array = str_split("0123456789bcdfghjkmnpqrstvwxyz");

str_split takes an optional 2nd param, the chunk length (default 1), so you can do things like:

$array = str_split("aabbccdd", 2);

// $array[0] = aa
// $array[1] = bb
// $array[2] = cc  etc ...

You can also get at parts of your string by treating it as an array:

$string = "hello";
echo $string[1];

// outputs "e"
