/**
|
|
* Purpose: DBO/ADO
|
|
*
|
|
* Description:
|
|
* A MySQL functions wrapper. Provides ability to get results as arrays
|
|
* and query logging (with execution time).
|
|
*
|
|
* Example usage:
|
|
*
|
|
* <code>
|
|
* require('dbo.php');
|
|
*
|
|
* // create and connect the object
|
|
* $db = new DBO(array(
|
|
* 'host'=>'localhost',
|
|
* 'login'=>'username',
|
|
* 'password'=>'password',
|
|
* 'database'=>'database'));
|
|
*
|
|
* // read the whole query result array (of rows)
|
|
* $all_rows = $db->all("SELECT a,b,c FROM table");
|
|
*
|
|
* // read the first row with debugging on
|
|
* $first_row_only = $db->one("SELECT a,b,c FROM table WHERE a=1", TRUE);
|
|
*
|
|
* // emulate the usual MySQL way of reading query results
|
|
* if ($db->q("SELECT a,b,c FROM table")) {
|
|
* while ( $row = $db->farr() ) {
|
|
* print $row['a'].$row['b'].$row['c'];
|
|
* }
|
|
* }
|
|
*
|
|
* // show a log of all queries, sorted by execution time
|
|
* $db->show_log(TRUE);
|
|
* </code>
