title: mssql_bind and fatala error only variable can be passed by reference
body: <p>I want to invoke a mssql procedure via php</p>
  
  <pre><code>$link = mssql_connect($this-&gt;serverName, $this-&gt;user, $this-&gt;password);
      mssql_select_db($this-&gt;db);
  
      // Create a new statement
      $stmt = mssql_init($this-&gt;owner . '.buf_ins_pilot', $link);
  
      // Bind values here
      // (polaczenie, nazwa, wartosc, typ, output, null)
      mssql_bind($stmt, "@ach_kod_systemu", "", SQLVARCHAR);
  </code></pre>
  
  <p>And I get</p>
  
  <pre><code>Fatal error: Only variables can be passed by reference
  </code></pre>
  
  <p>It`s on line with mssql_bind. I'm looking whole day solution for that and I don't know what am I doing wrong. It's almoust copy/paste from php manual</p>
