Php xml解析foreach循环+；只插入一条记录？

我一辈子都搞不懂如何让这段代码处理多条记录。代码工作正常，它只插入第一条记录，然后停止

提要：

PHP：

<?php 

$con=mysqli_connect("localhost","vadevco_reticket","3wer5top","vadevco_reticket");

if( ! $xml = simplexml_load_file('feed.xml') ) { 
    echo 'unable to load XML file'; 
} else { 
    foreach( $xml as $event ) { 
$idrandom = rand(0,99);
        $title = $event->item->title; 
        $description = $event->item->description;
        $link = $event->item->link;
        $guid = $event->item->guid;
        $pubDate = $event->item->pubDate;
        $image_t = $event->item->image_thumb;
        $image_l = $event->item->image_large;
        $displayDates = $event->item->displayDates;
$sql = "INSERT INTO `vadevco_reticket`.`events` (`title`, `description`, `pubDate`, `image_t`, `image_l`, `displayDates`, `id`, `event_id`) VALUES ('$title', '$description', '$pubDate', '$image_t', '$image_l', '$displayDates','','$idrandom')";
mysqli_query($con,$sql);

        foreach( $event->item->showDates->showDate as $eventDate ) {        
            $date = $eventDate->date;
            $venue = $eventDate->venue;
            $complex = $eventDate->complex;
            $region = $eventDate->region;
            $costs = $eventDate->costs;
$sql2 = "INSERT INTO `vadevco_reticket`.`instances` (`id`, `event_id`, `date`, `venue`, `complex`, `city`, `region`, `costs`) VALUES ('', '$idrandom', '$date', '$venue', '$complex', '$city','$region','$costs')";
mysqli_query($con,$sql2);
          }


 } 

    } 

?>

您需要遍历项目，而不是xml本身：

foreach( $xml->item as $event ) { 
  $idrandom = rand(0,99);
  $title = $event->title; 
  $description = $event->description;
  ...
}

-在你的例子中：你犯了一个错误，仔细检查你循环的每个变量是否包含你要查找的内容，然后修复它。这很简单，我们对此无能为力。另一个提示：将代码分成子例程。让一个例程做一件特定的事情。测试每个例程是否运行良好，然后将这些例程组合在一起。这通常会自动工作，否则很容易调试。与比较：请停止连接查询，学习如何使用准备好的语句。@tereško谢谢，你能详细介绍一下吗，这样我就知道该研究什么了？@Chris'Horris'Edington，查看准备好的语句。应该给你一些指示。
