  62 <h1>Table Data</h1>
  63
  64 <p>These functions let you fetch table information.</p>
  65
  66 <h2>$this->db->list_tables();</h2>
  67
  68 <p>Returns an array containing the names of all the tables in the database you are currently connected to.  Example:</p>
  69
  70 <code>$tables = $this->db->list_tables();<br />
  71 <br />
  72 foreach ($tables as $table)<br />
  73 {<br />
  74 &nbsp;&nbsp; echo $table;<br />
  75 }
  76 </code>
  77
  78
  79 <h2>$this->db->table_exists();</h2>
  80
  81 <p>Sometimes it's helpful to know whether a particular table exists before running an operation on it.
  82 Returns a boolean TRUE/FALSE.  Usage example:</p>
  83
  84 <code>
  85 if ($this->db->table_exists('table_name'))<br />
  86 {<br />
  87 &nbsp;&nbsp; // some code...<br />
  88 }
  89 </code>
  90
  91 <p>Note:  Replace <em>table_name</em> with the name of the table you are looking for.</p>
