How to replace all newline and tab charcaters with their respective \x code using php or javascript?

Hello I want to replace all newline characters and tab characters with \n and \t respectively.

Consider the following code markup

<!doctype html>
<html>
   <head>
      <title>Test</title>
      <meta charset="UTF-8">
   </head>
   <body>
   </body>
</html>

After replacement the code should look like this

<!doctype html>\n<html>\n\t<head>\n\t\t<meta charset=\"utf-8\">\n\t\t<title>Test</title>\n\n\t\t\n\t</head>\n\t<body>\n\t\n\t</body>\n</html>

How to achieve this?

and the also can we reverse this process? i.e can we get back the original form. If yes then How???

What you want is something like this 

 <?php
       $str = '
       <!doctype html>
        <html>
           <head>
              <title>Test</title>
              <meta charset="UTF-8">
           </head>
           <body>
           </body>
        </html>
       ';

       echo $str;
       $arr = array("\n","\t","\r");
       echo $str = str_replace($arr, "", $str);
    ?>

// output - <!doctype html><html> <head> <title>Test</title> <meta charset="UTF-8"> </head> <body> </body></html>
