[Resolved] split() by char

[Kudose]

I was wondering if there was a way to split a string by character instead of by a secified character.

Like I want this:

$string = Hello

split(dunno, $string);

echo $string[0]; //outputs H only
etc...

PHP 5 has str_split, but you'll need to custom it.

$chars = array();
for($i=0;$i<strlen($string);$i++) {
   $chars[] = $string{$i};
}

Can you think of anything that would work with PHP 4.3.4?

Thanks for the advice already. 🙂

Here is what I basiaclly want to do. I want to convert this, which does split by spaces, to split by each character.

//gather posted info and split it up
$post = $_POST['post'];
$post = strip_tags($post);
$post = stripslashes($post);
$arr = explode(" ", $post);
$num = count($arr);

//check to see if they are trying to flod server
if($post>chr(1000)){ echo "Post is too big.  Try again"; exit(); }
//start for statement, making a random color each pass and editing the post variable
for($i=0; $i<$num; $i++){
$color = rand(0,6);
//start switch
switch($color){
	case "0":
		$s = "";
		$e = " ";
		break;
	case "1":
		$s = "[red]";
		$e = "[/red] ";
		break;
	case "2":
		$s = "[blue]";
		$e = "[/blue] ";
		break;
	case "3":
		$s = "[purple]";
		$e = "[/purple] ";
		break;
	case "4":
		$s = "[gray]";
		$e = "[/gray] ";
		break;
	case "5":
		$s = "[orange]";
		$e = "[/orange] ";
		break;
	case "6":
		$s = "[green]";
		$e = "[/green] ";
		break;
}
//end switch
$glue = $s.$arr[$i].$e;
$arr[$i] = $glue;
} //end for statement
//end cutting and pasting
//begin displaying
echo "<h1>Copy and paste</h1><br>";
for($q=0; $q<=$num; $q++){
	echo $arr[$q];
}

Just make the code I gave you above a function, then use it instead of explode.

if(!function_exists('str_split')) {
   function str_split($string) {
      $chars = array();
      for($i=0;$i<strlen($string);$i++) {
         $chars[] = $string{$i};
      }
      return $chars;
   }
}

// now instead of $arr = explode(" ", $post); 
$arr = str_split($post);

You are THE man. Thanks alot. 🙂

Actually, why not simply access the characters right away?

You're going through alot just to do that.

e.g.

$string = "Hello";

echo $string{0}; //outputs H only

Awesome. Thanks! 🙂
