所以我使用的是有人让我编辑的面板，他们使用的是过时版本的php / MySQL。我已将mysql_更新为mysqli_等。
现在当我在XAMPP上加载页面时，我得到一个空白的白色屏幕，只显示
MySQL错误：
没有别的。 index.php包含一个显示MySQL错误的页面。
包含页面的代码如下。
<?php
class Database {
/*
* Constructor - connects to database.
* @global $params - core parameters from glob.php
*/
public function __construct() {
global $params;
$link = mysqli_connect( $params['db']['hostname'], $params['db']['username'], $params['db']['password'] );
mysqli_select_db($link, $params['db']['database'] );
}
/*
* Query - executes a MySQL query.
* @param $string - required. the input SQL string.
* @return $q - the resulting query.

public function query( $string ) {

if( !$q ) {
echo "<div style=\"font-family: tahoma; font-size: 11px; width: 400px; margin: auto;\">";
echo "<big><center><strong>MySQL Error:</strong></center></big>";
echo mysqli_error();
echo "</div>";
die();
}
return $q;
}
