Example:</p> <code>$tables = $this->db->list_tables()<br /> <br /> foreach ($tables as $table)<br /> {<br /> echo $table;<br /> } </code> <h2>$this->db->table_exists();</h2> <p>Sometimes it's helpful to know whether a particular table exists before running an operation on it. Returns a boolean TRUE/FALSE. Usage example:</p> <code> if ($this->db->table_exists('table_name'))<br /> {<br /> // some code...<br /> } </code> <p>Note: Replace <em>table_name</em> with the name of the table you are looking for.</p> </div> <!-- END CONTENT --> <div id="footer"> <p> Previous Topic: <a href="fields.html">Field MetaData</a> · <a href="#top">Top of Page</a> · <a href="../index.html">User Guide Home</a> · Next Topic: <a href="../email.html">Email Class</a> <p> <p><a href="http://www.codeigniter.com">Code Igniter</a> · Copyright © 2006 · <a href="http://www.pmachine.com">pMachine, Inc.</a></p> </div> </body> </html>
