php下while中使用mysql查询语句问题-问答-阿里云开发者社区-阿里云

php的mysql查询语句可不可以这样用呢？

$query = "SELECT name FROM bank WHERE area LIKE 'aaa'";
$result = mysql_query($query) or die(mysql_error());
while($row = mysql_fetch_array($result)) {
    $http = $row['http'];
    $task_query = "SELECT * FROM task WHERE link LIKE'%$http%'";
    $task_result = mysql_query($task_query) or die(mysql_error());
    while($task = mysql_fetch_array($task_result));
            echo $task['high'].'<br />';
    }
