这个问题在这里还没有答案：PDO 语句返回 FALSE 1 个答案

上面的问题只是错误处理看到我得到的错误！（已经有错误处理）并且如果我在 phpmyadmin 中运行它们，我的所有查询都可以正常工作。

您好我正在尝试进入我的动态页面。但我收到警告：

警告：在第 137 行为 foreach() 提供的参数无效

我试图修复它，但我似乎可以让它工作。我试图改变

foreach($results as $row)

至：

foreach($row = $results->fetch(PDO::FETCH_ASSOC))

和

foreach($row = $results->fetchAll())

但比我得到的错误：

解析错误：语法错误，第 137 行出现意外的 ')'

我试图在互联网上找到答案，但我可以找到解决这个问题的答案。

有人知道我该如何解决这个问题吗？而我做错了什么......我尝试使用 PDO。我对 PHP 和 PDO 还是有点陌生​​。

我的代码：

    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script> 
<?php 
    include('php/loginHandlerconnect.php'); 

    ini_set('display_errors',1);

因为当我运行这个页面时它可以工作！但它不是 PDO...查看此更新之前的代码以了解我如何将代码更改为 PDO 请注意我也在该代码中使用函数！如果我知道将其更改为 PDO 时我做错了什么，也许这会解决这个问题？但我不知道我做错了什么！！

尝试更新

$sql = 'SELECT vacature.*, werkgever.image, werkgever.plaats, werkgever.provincie, werkgever.naamBedrijf FROM vacature LEFT JOIN werkgever ON (vacature.werkgeverID = werkgever.werkgeverID) ORDER BY vacature.datum DESC LIMIT '. $start .', '. $limit .''; 
$results = $db->query($sql);

至

$sql = $db->query('SELECT vacature.*, werkgever.image, werkgever.plaats, werkgever.provincie, werkgever.naamBedrijf FROM vacature LEFT JOIN werkgever ON (vacature.werkgeverID = werkgever.werkgeverID) ORDER BY vacature.datum DESC LIMIT '. $start .', '. $limit .''); 
$results = $db->fetchAll($sql);

实际上没有做 fetchAll 你的 $result 是一个 PDO 查询对象

而且foreach($row = $results->fetch(PDO::FETCH_ASSOC))您刚刚初始化了 $row 变量，您忘记在那里定义 $value 所以语法应该是foreach($array = $results->fetch(PDO::FETCH_ASSOC) as $row)虽然我不太确定我们是否可以$array = $results->fetch(PDO::FETCH_ASSOC)在 foreach 中使用
