動作腳本字符串屏蔽功能

Question

以下是一個用於屏蔽字符串的php功能。有人可以給我這個功能的動作平等。

public static function simple_encrypt($input) { 
     $return = array(); 
     for($i = 0; $i < strlen($input); $i++){ 
      $ascii = ord(substr($input, $i, 1)) * 2; 
      $return[] = base_convert($ascii, 10, 32); 
     } 
     return sprintf('RL%s', implode('', $return)); // "RL" ensures it starts with a letter 
} 

Answer 1

public static function simple_encrypt(input:String):String { 
     var ret = []; 
     var ascii:Number; 
     for(var i:Number = 0; i < input.length; i++) { 
      ascii = input.charCodeAt(i) * 2; 
      ret.push(ascii.toString(32)); 
     } 
     //I don't speak php, so I am assuming that 
     //RL doesn't have any syntactical meaning with sprintf 
     return "RL" + ret.join(''); //joins everything to a single string. 
}
