MySQL while循环不会停止

Question

我最近创建了一个PHP/MySQL while循环,它根据我的参数获取数组.根据我所知道的,当没有更多行可以抓取时,它应该结束.我只是继续前进,直到我停止加载页面.

while($row = mysql_fetch_array(mysql_query("SELECT username,password,title,message FROM notifications WHERE dateset = '$date'"))){
    $test = new Boxcar($row['username'],$row['password']); 
    $test->send($row['title'],$row['message']);
}

Answer 1

尝试这样的情况很有可能每次进入while循环时都会重新运行内联查询

$result = mysql_query("SELECT username,password,title,message FROM notifications WHERE dateset = '$date'");

while($row = mysql_fetch_array($result)) {
    $test = new Boxcar($row['username'],$row['password']); 
    $test->send($row['title'],$row['message']);
}
