mysql_fetch_array如何屏蔽无数据错误提示
我在做PHP连接数据库时,用mysql_fetch_array取数据库数据。
但是如果数据库中表没有内容时,会提示至少需要1个元素的错误提示。
我想做成如果没有数据,输出"没有数据",并不会显示php错误提示,请问怎么做?
回复讨论(解决方案)
error_reporting(0);$query = mysql_query($sql);mysql_fetch_array($query);........
不可能的,不会出现这样的错误!
error_reporting(0);$query = mysql_query($sql);mysql_fetch_array($query);........
error_reporting(0);
这个语句是不是屏蔽所有的报错?
error_reporting(0);$query = mysql_query($sql);mysql_fetch_array($query);........
error_reporting(0);
这个语句是不是屏蔽所有的报错?
是的。 你如果想屏蔽单条报错,可以这样写
@mysql_fetch_array($query);
你最好还是贴出代码瞧瞧,示例:
$row = mysql_fetch_array($result)
if (!$row){
exit("没有数据");
}
别胡扯了!
如果 mysql_fetch_array 会报错的话,那么一定是报传入的参数不是mysql retsult资源
而这个错误表示之前的查询 mysql_query 出现了错误,是不可屏蔽的!
$rs = mysql_query('select * from tbl_name where 1=0'); //这一定是查不到结果的print_r(mysql_fetch_array($rs)); //只会打印空数组,而就不报错
判断没有查询结果得用 if(mysql_num_rows($rs) == 0)
加上@符号就可以屏蔽错误提示
谢谢大家。@ 和 error_reporting(0);都可以
