| 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 | 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 | // 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>
