title: PHP: Using str_pad not working? Why?
body: <p>I have a string, its content is "24896". Now I want to add some zeros to the left, so I tried:</p>
  
  <pre><code>$test = str_pad($myString, 4, "0", STR_PAD_LEFT);
  </code></pre>
  
  <p>The result is "24896" again, no zeros added to the left. Am I missing something here?</p>
  
  <p>Thanks!</p>
