63
64<p>These functions let you fetch table information.</p>
65
admin3dd978f2006-09-30 19:24:45 +0000[diff] [blame]66<h2>$this->db->list_tables();</h2>
adminfb28bb82006-09-24 17:59:33 +0000[diff] [blame]67
68<p>Returns an array containing the names of all the tables in the database you are currently connected to. Example:</p>
69
admin3dd978f2006-09-30 19:24:45 +0000[diff] [blame]70<code>$tables = $this->db->list_tables()<br />
adminfb28bb82006-09-24 17:59:33 +0000[diff] [blame]71<br />
72foreach ($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.
82Returns a boolean TRUE/FALSE. Usage example:</p>
83
84<code>
85if ($this->db->table_exists('table_name'))<br />
86{<br />
87&nbsp;&nbsp; // some code...<br />
88}
89</code>

91<p>Note: Replace <em>table_name</em> with the name of the table you are looking for.</p>
