@shane_carrauthorSep 20.2006 — Thanks pcthug. urlencode seems to work well, but for urldecode, it's at like .83 seconds or something when I run the text that was produced from this script. Is there a way to remove semicolons from text and put them back again? ex:

[code=php]$a = "test;test;test(semi)test";
$b = str_replace(";", "(semi)", $a);
//works fine, but decoded
$c = str_replace("(semi)", ";", $b);
echo (($a==$c)?"It worked":"See? How can I avoid this problem? This is the only reason that I'm using urlencode and decode for this. What else can I do?");[/code]

@shane_carrauthorSep 22.2006 — Okay, I got this code, and it seems to work:

[code=php]$char = ";"; //character to remove
$rep = "¤"; //character to replace
$mark = "<orig"; //string to show an already-existent character
$orig = "string to remove character from";
$form = str_replace($rep, $rep.$mark, $orig); //take all of the $rep character and show that it already existed
$form = str_replace($char, $rep, $form); //remove all $char's and replace them with $rep's
//$form is the formatted string, and it has none of $char.

$temp = explode($rep, $form); //find all $reps and split the array
if(!is_array($temp))$temp=array(2); //if there were no $rep's in the formatted string
$new = $temp[0];
array_shift($temp);
foreach($temp as $value){ //evaluate every value in the $temp array
if(substr($value, 0, strlen($mark))==$mark){ //if the character is marked original
$new .= $rep.substr($value, strlen($mark)); //add $rep
}else{
$new .= $char.$value; //otherwise add $char
}
}
//$new is now the un-formatted string, and $orig == $new.[/code]

So I suppose that I'm done now!

Success!
