我试图用数组中的值获取动态创建的列表元素的id，但它不起作用。如何获取特定列表项的ID？

解析错误：语法错误，意外＆＃39;＆＃39; （T_ENCAPSED_AND_WHITESPACE）

数组：

Answer 1

以上代码示例是一个还是两个文件？如果以上是一个文件，则缺少开头

Answer 2

替换您的try块，如下所示：

try {
                        $dbh = new PDO("mysql:host=$hostname;dbname=loc",$user,$password);

                        $dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); // <== add this line
                         $sql = "delete from posts where id = ".$row['id']."  limit 1"; // oder (longitude between $loo and $lo or latitude  between $laa and $la) versuchen
   }
