68
69<p>These functions let you fetch table information.</p>
70
admin3dd978f2006-09-30 19:24:45 +0000[diff] [blame^]71<h2>$this->db->list_tables();</h2>
adminfb28bb82006-09-24 17:59:33 +0000[diff] [blame]72
73<p>Returns an array containing the names of all the tables in the database you are currently connected to. Example:</p>
74
admin3dd978f2006-09-30 19:24:45 +0000[diff] [blame^]75<code>$tables = $this->db->list_tables()<br />
adminfb28bb82006-09-24 17:59:33 +0000[diff] [blame]76<br />
77foreach ($tables as $table)<br />
78{<br />
79&nbsp;&nbsp; echo $table;<br />
80}
81</code>
82
83
84<h2>$this->db->table_exists();</h2>
85
86<p>Sometimes it's helpful to know whether a particular table exists before running an operation on it.
87Returns a boolean TRUE/FALSE. Usage example:</p>
88
89<code>
90if ($this->db->table_exists('table_name'))<br />
91{<br />
92&nbsp;&nbsp; // some code...<br />
93}
94</code>
95
96<p>Note: Replace <em>table_name</em> with the name of the table you are looking for.</p>
