title: How to Upper Serbian letters, Č,Ć,Š,Đ,Ž in PHP
body: <p>I got a problem to make upper letters in php.</p>
  
  <p>I tried this function:</p>
  
  <pre><code>function strtouper_srbija($string) {
      $low=array("č" =&gt; "Č", "ž" =&gt; "Ž", "Š" =&gt; "š","Đ" =&gt; "đ","Č" =&gt; "č");
      return strtoupper(strtr($string,$low));
  }
  </code></pre>
  
  <p>and tried to use with some POST data from html page,text filed,but no succes,so if you have solutions,will be fine..</p>
  
  <p>Also, I found solution with CSS, with <code>text-transform: uppercase;</code>, but will be fine to have PHP example.</p>
