+<h1>Table Data</h1>
+
+<p>These functions let you fetch table information.</p>
+
+<h2>$this->db->tables();</h2>
+
+<p>Returns an array containing the names of all the tables in the database you are currently connected to. Example:</p>
+
+<code>$tables = $this->db->tables()<br />
+<br />
+foreach ($tables as $table)<br />
+{<br />
+&nbsp;&nbsp; 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 />
+&nbsp;&nbsp; // some code...<br />
+}
+</code>
+
+<p>Note: Replace <em>table_name</em> with the name of the table you are looking for.</p>
