title: regular expression and forward slash
body: <p>i'm searching for keywords in a string via a regular expression. It works fine for all keywords, exept one which contains a forward slash in it:  "time/emit" .</p>
  
  <p>Even using <code>preg_quote($find,'/')</code>, which escapes it, i still get the message:</p>
  
  <pre><code>Unknown modifier 't' in /frontend.functions.php  on line 71
  </code></pre>
  
  <p>If i print the find pattern, it shows <code>/time\\/emit/</code> . Without preg_quote, it shows <code>/time/emit/</code>  and both return the same error message.</p>
  
  <p>Any bit of knowledge would be useful.</p>
