title: PDO execute($input_parameter) protects from sql injections as bindParam/bindValue?
body: <p>Does <code>execute($input_parameter)</code> protect from sql injections just like <code>bindParam/bindValue</code>?</p>
  
  <p>If the answer is yes, <code>bindParam()/bindValue()/execute()</code> are invulnerable to any sql-inject attack? Or I need to take measures to prevent such attacks?.</p>
  
  <p>Thanks for help!.</p>
