将此PHP转换为Actionscript？

Note: I have read https://meta.stackexchange.com/questions/128548/what-stack-overflow-is-not/129362#129362

It says "try to write the code yourself and post what you've tried when you run into problems." which is what I am doing here.

The original PHP code:

$text = "Hello world, I am rainbow text!";
$texty = '';
    $colors = array('ff00ff','ff00cc','ff0099','ff0066','ff0033','ff0000',
                    'ff3300','ff6600','ff9900','ffcc00','ffff00','ccff00',
                     '99ff00','66ff00','33ff00','00ff00','00ff33','00ff66',
                     '00ff99','00ffcc','00ffff','00ccff','0099ff','0066ff',
                     '0033ff','0000ff','3300ff','6600ff','9900ff','cc00ff'); 
        $i = 0;
$textlength = strlen($text);
while($i<=$textlength){
foreach($colors as $key=>$value){
    if (isset($text[$i])) {
        $texty .= "<font color=\"#".$value."\">".$text[$i]."</font>";
    }
    $i++;
}
$texty = str_replace("> <",">&nbsp;<",$texty);
echo $texty;
}

What I've butchered it down to:

var text = "Hello world, I am rainbow text!";
var texty = '';
colors = new Array

('ff00ff','ff00cc','ff0099','ff0066','ff0033','ff0000',
 'ff3300','ff6600','ff9900','ffcc00','ffff00','ccff00',
 '99ff00','66ff00','33ff00','00ff00','00ff33','00ff66',
 '00ff99','00ffcc','00ffff','00ccff','0099ff','0066ff',
 '0033ff','0000ff','3300ff','6600ff','9900ff','cc00ff'); 
var i = 0;

var textlength = text.length;
var key = '';
var value = '';
while(i <= textlength){
for each(colors as key=>value){
    if (text[i] != undefined) {
        texty .= "<font color=\"#" + value + "\">" + text[i] + "</font>";
    }
    i++;
}
texty.replace("> <",">&nbsp;<");
//document.write(texty);
}

I've been testing this as Javascript, which is why I have document.write commented in the code. However, I still cannot get it to work. I hate to be so vague but... can someone tell me where I screwed up?

Got something with your code, but didnt get what you trying to do. Check out fiddle.

this looks better...

posted code here, in case i delete fiddle link.

var text = "Hello world, I am rainbow text!";
var texty = '';
colors = ['ff00ff','ff3300','ff6600','ffff66','00ff99','00ffcc','00ffff','00ccff','0099ff','0066ff','0033ff','0000ff','3300ff','6600ff','9900ff','cc00ff']; 
var i = 0;


var textlength = text.length;
var key = '';
var value = '';
while(i <= textlength){
    var t = text.charAt(i);

    if (t!= undefined) {
        texty += "<font color=\"#" + colors[i%colors.length] + "\">" +  t + "</font>";
    i++;
}
}

texty.replace("> <",">&nbsp;<");
document.write(texty);

Actionscript is basically a dialect of Javascript, so you can test your code in an interactive shell in Firebug or Chrome's developer tools. There you'll get error reports.

Looking at your code, I can immediately spot a few errors, there might be others too:

for each(colors as key=>value){

This is not a valid construct. Write as:

for (var key in colors) {
    var value = colors[key];

This is not valid syntax:

texty .= 

Use:

texty += 

This is valid, but doesn't do what you expect:

texty.replace("> <",">&nbsp;<");

You need to assign the return value:

texty = texty.replace("> <",">&nbsp;<");

There's probably more ...
