/*** mysqli  op mysql demo*//***公用函数*//***功能：列出一个数据库的所有表*@param$dbname*@param$con*/functionlist_tables($dbname,$con){mysql_select_db($dbname,$con)or die("选择数据库失败!");$res= mysql_query("SHOW TABLES");$tables=array();while($row= mysql_fetch_array($res)){echo$row[0] .‘
‘;}mysql_free_result($res);//    return $tables;}/***利用msyql方法取得所有库的名字*/$mysqlCon= mysql_connect(‘localhost‘,‘root‘,‘2015‘);$set= mysql_query(‘SHOW DATABASES;‘);$dbs=array();while($db= mysql_fetch_row($set))$dbs[] =$db[0];//var_dump($dbs);echo‘

这个是mysql操作输出的结果：

‘;//print_r($dbs);/***这个用来显示数据库名称*/foreach($dbsas$key=>$value){echo‘‘.$key."=>".$value.‘
‘;list_tables($value,$mysqlCon);}echo‘

这个是msyqli操作输出的结果：

‘;$mysqliCon= mysqli_connect(‘localhost‘,‘root‘,‘2015‘);$result= mysqli_query($mysqliCon,‘show databases‘);$dbs2=array();while($db=mysqli_fetch_row($result))$dbs2[] =$db[0];print_r($dbs2);

结果如下：
