PHP列出MySQL中所有数据库的方法

本文实例讲述了PHP列出MySQL中所有数据库的方法。分享给大家供大家参考。具体如下：

PHP代码如下：

<?phpdefine( 'NL', "/n" );define( 'TB', ' ' );// connecting to MySQL.$conn = @mysql_connect( 'localhost', 'username', 'password' )    or die( mysql_errno().': '.mysql_error().NL );// attempt to get a list of MySQL databases// already set up in my account. This is done// using the PHP function: mysql_list_dbs()$result = mysql_list_dbs( $conn );// Output the listecho '<ul class="projects">'.NL; ///* USING: mysql_fetch_object() // --------------------------- while( $row = mysql_fetch_object( $result ) ):  echo TB.'<li>'.$row->Database.'</li>'.NL; endwhile; //*/ /* USING: mysql_fetch_row() // ------------------------ while( $row = mysql_fetch_row( $result ) ):  echo TB.'<li>'.$row[0].'</li>'.NL; endwhile; //*/ /* USING: mysql_fetch_assoc() // -------------------------- while( $row = mysql_fetch_assoc( $result ) ):  echo TB.'<li>'.$row['Database'].'</li>'.NL; endwhile; //*/echo '</ul>'.NL;// Free resources / close MySQL Connectionmysql_free_result( $result );mysql_close( $conn );  ?>

希望本文所述对大家的php程序设计有所帮助。
