breaking down a string

[sloppstack]

Hi all, I am new to PHP I have been learning the basics for a couple weeks now. I am trying to write a hang-man program and I need a way break down a string into an array of letters. Example, if the word is TEST i want to be able to turn it into an array that contains the elements (T, E, S, T). How can I do this? thanks.

thank you very much Thorpe, I have been to a bunch of PHP tutorials but none had anything on that function.

actually... i just noticed. it seems it is a php5 function. this should work if your using php4.x.x

function split_each_letter($str) {
    for ($i=0;$i<=strlen($str);$i++) {
        $arr[] = substr($str,$i,1);
    }
    return $arr;
}

More likely:

function splitIntoChars($str) {
	$ret = array();
	$len = strlen($str);
	for ($i = 0; $i < $len; $i++) {
		$ret[] = $str{$i};
	}
	return $ret;
}

That said, what do you need to do with strings that you need them as character arrays?
If you need to access each character individually, do it with the $str{$ch} notation.

Hi laserlight, i don't understand one of your code, why must we put {} instead of () for the "$ret[] = $str{$i};"

it lets you reference each position in a string.
example;

  $string = 'abcdefg';
  echo $string{0}."\n";

returns a

  $string = 'abcdefg';
  echo $string{4}."\n";

returns e

I've looked at the docs and didn't see a built-in function to do this, but if there is one, please let me know. I'd like to be able to split a string into an array based on a character. Like so:

$str = '04:25:39';
$arr = someFunc($str);
$arr[0] = '04';
$arr[1] = '25';
$arr[2] = '39';

If there isn't one, I'm sure I could write one, but why reinvent the wheel...  Any info would be teh awesome!

LOL, thanks, dude. Not sure how I missed that. Must not have looked to hard, as I've seen that function mentioned before.

Lol, ok...

I'm dumb too, thanks for the $str{$chr} thingy.
