$items=”49|48″;//49|48|45|61……
$tmp = explode(“|”, $items);
$coun = count($tmp);
for( $i=0;$i < $coun; $i++){
$obj_db->simplequery(“update member set yz=’1′ where );
}
上面代码执行是正确的，达到了以下效果：
$obj_db->simplequery(“update member set yz=’1′ where );
$obj_db->simplequery(“update member set yz=’1′ where );
……
现在$items数组变成了这样：
$items=”49,3|48,2″;//49,3|48,2|45,6|61,3……
执行如下：
$items=”49,3|48,2”;
$tmp = explode(“|”, $items);
$coun = count($tmp);
for( $i=0;$i < $coun; $i++){
$tmp2 = explode(",", $tmp[$i]);
$obj_db->simplequery(“update member set yz=’1′ where );
}
这段代码执行后效果如下：
$obj_db->simplequery(“update member set yz=’1′ where );
只执行了数组$tmp2[0]最后一个=48值，
如何能让它执行所有呢？即：
$obj_db->simplequery(“update member set yz=’1′ where );
$obj_db->simplequery(“update member set yz=’1′ where );
……
谢谢！
回复讨论(解决方案)
$items=”49,3|48,2″;
$tmp = explode(“|”, $items);
$coun = count($tmp);
for( $i=0;$i < $coun; $i++){
$tmp2 = explode(",", $tmp[$i]);
//$obj_db->simplequery(“update member set yz=’1′ where );
echo “update member set yz=’1′ where , php_eol;
}
update member set yz=’1′ where id=49
update member set yz=’1′ where id=48
没有问题
$items=”49,3|48,2″;
$tmp = explode(“|”, $items);
$coun = count($tmp);
for( $i=0;$i < $coun; $i++){
$tmp2 = explode(",", $tmp[$i]);
//$obj_db->simplequery(“update member set yz=’1′ where );
echo “update member set yz=’1′ where , php_eol;
}
update member set yz=’1′ where id=49
update member set yz=’1′ where id=48
没有问题
谢谢！表达错了，主要问题如下：
for( $i=0;$i < $coun; $i++){
$tmp2 = explode(",", $tmp[$i]);
$query="select * from member where ;
$result=$obj_db->simplequery($query);
$num=$obj_db->numrows($result);
}
执行后$num怎么是1啊？明明是2条符合要求的，如何才能等于2
谢谢！
