am在使用php从sql返回值并遇到此错误时遇到问题:
未定义的偏移量:0
这是我的代码
<?php
$connect = mysqli_connect("localhost","root", "","gocar");
$query = "SELECT * FROM `userdetails` u RIGHT JOIN `bookingdetails` b ON
u.id=b.user_id ORDER by b.id DESC LIMIT 10";
$result = mysqli_query($connect,$query);
while ($row = mysqli_fetch_assoc($result))
{
print_r($row[0]);
}
?>
何时使用此
print_r($ row);
一切正常,并获得所有10个值...但是现在我需要获取特定的索引!
该怎么做??
