入门例子php mysql中读取表中数据失败,求大侠指教
1.问题:用php读mysql中的一张表,怎么也读不出来,页面有时空白,有时有php中的一小节代码,苦调了一天了,求指导!感激不尽!!
2.mysql中,数据库:test;表名:apple;(字段:firstname,lastname)
3.index.php(试过连接数据库成功)
代码:
- PHP code
<!-- Code highlighting produced by Actipro CodeHighlighter (freeware) http://www.CodeHighlighter.com/ --> <title>php分页示例</title> <meta http-equiv="content-Type" content="text/html; charset=utf-8"> <?php $dbh = @mysql_connect("localhost","root",""); if(!$dbh){die("error");} @mysql_select_db("test", $dbh); $sql = "SELECT * FROM apple"; ?> $rs = mysql_query($sql, $dbh); while($row = mysql_fetch_array($rs)) echo $row[id]; echo $row[name]; echo '<br>'; ?> @mysql_close($dbh); ?>
请各大侠帮帮忙,叩谢!!
------解决方案--------------------
日志错误只是有个默认图标不存在的提示,没有关系的.
仔细看了下代码
while($row = mysql_fetch_array($rs))
echo $row[id];
echo $row[name];
echo '
';
?>
这里添加上括号
while($row = mysql_fetch_array($rs)) {
echo $row[id];
echo $row[name];
echo '
';
}
?>
保存后刷新 看看
另外你不说数据库内是
(字段:firstname,lastname)
怎么跑出个 $row['id']? $row['name']?出来了
