title: List of PDOStatement::bindParam data_type parameters
body: <p>Is there a list describing all of the data_type parameters you can use in <code>PDOStatement::bindParam()</code> ? If none, what do you commonly use, and for what type of field ?</p>
  
  <p>According to PHP manual: <em>data_type</em> Explicit data type for the parameter using the PDO::PARAM_* constants. </p>
  
  <p>I know about the <code>PDO::PARAM_INT</code> and <code>PDO::PARAM_STR</code> . I've heard of <code>PDO::PARAM_LOB</code> but I wasn't sure how and when to use that, though. (for date ?)</p>
