Question

我可以使用正确的代码，但我希望能够使用不起作用的对象和方法。重复数据库中的相同条目，直到查询崩溃。我看到其他人在while语句中有查询，但我认为我使用的方法应该只查询一次语句，但我可能错了。感谢。

<?php
include '/functions/MySQL.php';
$MySQL = new MySQL;
$con = mysqli_connect("host","user","password","db");
$result = mysqli_query($con,"SELECT * FROM reportLogger WHERE Moderator='jackginger'");
while($row = mysqli_fetch_array($MySQL->getReports('jackginger'))) {
    $time           = $row['Time'];
    $moderator      = $row['Moderator'];
    $reason         = $row['Reason'];

    // Now for each looped row

    echo "<tr><td>".$time."</td><td>".$moderator."</td><td>".$reason."</td></tr>";
}
?>

public function __construct(){
        $this->con = mysqli_connect("localhost","root","pass","Minecraft");
        // Check connection
        if (mysqli_connect_errno()) {
            echo "Failed to connect to MySQL: " . mysqli_connect_error();
        }
    }

    public function getUUID($username) {
        $result = mysqli_query($this->con,"SELECT UUID FROM loginLogger WHERE Username='" . $username . "'");
        return mysqli_fetch_array($result)[0];
    }

    public function getReports($username) {
        $result = mysqli_query($this->con,"SELECT * FROM reportLogger WHERE UUID='" . $this->getUUID($username) . "'");
        return $result;
    }

每次拨打while($row = mysqli_fetch_array($MySQL->getReports('jackginger')))时，您都会进行新的查询，因此一遍又一遍地提取相同内容。

解决方案可能是：

<?php
include '/functions/MySQL.php';
$MySQL = new MySQL;
$con = mysqli_connect("host","user","password","db");
$result = mysqli_query($con,"SELECT * FROM reportLogger WHERE Moderator='jackginger'");
$store = $MySQL->getReports('jackginger');
while($row = mysqli_fetch_array($store)) {
    $time           = $row['Time'];
    $moderator      = $row['Moderator'];
    $reason         = $row['Reason'];

    // Now for each looped row

    echo "<tr><td>".$time."</td><td>".$moderator."</td><td>".$reason."</td></tr>";
}
?>
