Token Problem... sorta
 

I've created a function called parsePost() here it is:[PHP]function parsePost($input){
$modify = $input;
$tokens = array();
while(false !== $openLocate = strpos($modify, chr(60))){
if(count($tokens) == 0){
array_push($tokens, substr($modify, 0, $openLocate));
} else {
array_push($tokens, chr(60) . substr($modify, 0, $openLocate));
if(false !== $closeLocate = strpos($tokens[count($tokens) - 1], chr(62))){
$temp = array_pop($tokens);
array_push($tokens, substr($temp, 0, $closeLocate + 1));
array_push($tokens, substr($temp, $closeLocate + 1));
}
}
$modify = substr($modify, $openLocate + 1);
}
if(count($tokens) == 0){
array_push($tokens, $modify);
} else {
array_push($tokens, chr(60) . $modify);
if(false !== $closeLocate = strpos($tokens[count($tokens) - 1], chr(62))){
$temp = array_pop($tokens);
array_push($tokens, substr($temp, 0, $closeLocate + 1));
array_push($tokens, substr($temp, $closeLocate + 1));
}
}
$temp = array();
for($i = 0; $i < count($tokens); $i++){
if(strlen($tokens[$i]) != 0){
array_push($temp, $tokens[$i]);
}
}
$tokens = $temp;
for($i = 0; $i < count($tokens); $i++){
$openLocate = strpos($tokens[$i], chr(60));
$closeLocate = strpos($tokens[$i], chr(62));
if($openLocate === 0 && $closeLocate === strlen($tokens[$i]) - 1){

} else {
$tokens[$i] == htmlentities($tokens[$i]);
}
}
return $tokens;
}[/PHP]It returns then input tokenized in the manner that I want, the problem is that for some reason it won't do the conversion of htmlentities as specified, can anyone tell me what's amiss here?

Never mind I figured it out: the error was here
$tokens[$i] == htmlentities($tokens[$i]);
I'm using a comparison operator rather than an assignment operator
-_-

Take THIS BBCode!
