title: How to insert `>` and `(` into MySQL?
body: <p>I do not know where is the problem that I can not insert <code>&gt;</code> and <code>(</code> into my MySQL database. </p>
  
  <p>I add a <code>addslashes($str)</code> but this still can leave the quote mark unescaped. </p>
  
  <p>Is there any string functions that can solve my problem?</p>
