现有用户名为root,密码为root的MYSQL数据库服务器，其中有个名为JWGL的数据库，如何使用PHP程序设计显示JWGL数据库中student表的前15条记录
------解决方案--------------------
mysql_connect('localhost', 'root', 'root') or die(mysql_error());
mysql_select_db('JWGL') or die(mysql_error());
$rs = mysql_query('select * from student limit 15') or die(mysql_error());
while($r = mysql_fetch_assoc($rs)) {
echo join(' ', $r) . '
';
}
------解决方案--------------------
<br /><br />mysql_connect('localhost', 'root', 'root') or die(mysql_error());<br />mysql_select_db('JWGL') or die(mysql_error());<br />//假设你的编号字段名为 id <br />$rs = mysql_query('select * from student order by id desc limit 15') or die(mysql_error());<br />while($r = mysql_fetch_assoc($rs)) {<br /> echo join(' ', $r) . '<br />';<br />}<br /><br /><br />$mysql_server_name='localhost';<br />$mysql_username='root';<br />$mysql_password='root';<br />$mysql_database='JWGL';<br />$mysql_table='student';<br />$conn=mysql_connect($mysql_server_name,$mysql_username,$mysql_password,$mysql_database) or die(mysql_error());<br />mysql_select_db($mysql_database,$conn);<br />$sql='SET NAMES UTF8';//if utf8<br />mysql_query($sql);<br /><br />$queStr ='SELECT * FROM '.$mysql_table.' ORDER BY id ASC LIMIT 0,15';//if pri key id<br />$result=mysql_query($queStr);<br />while($row = mysql_fetch_array($result)){<br /> echo $row[0]." ".$row[1]."<br />";//or $row["test_col"]<br />}<br />mysql_close($conn);<br />
