<h1>Table Data</h1>
<p>These functions let you fetch table information.</p>
<h2>$this->db->list_tables();</h2>
<p>Returns an array containing the names of all the tables in the database you are currently connected to. Example:</p>
<code>$tables = $this->db->list_tables();<br />
<br />
foreach ($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>
