Php 警告：file_get_contents（）要求参数1为有效路径，数组为16

我的脚本有问题，我试图连接到每个数组的每个url，但收到了警告。警告：file_get_contents要求参数1为有效路径，数组给定：第78行的/home/myusername/public_html/simple_html_dom.php中

下面是simple_html_dom.php的第78行：

$contents = file_get_contents($url, $use_include_path, $context, $offset);

以下是输出：

以下是PHP：

<?php
ini_set('max_execution_time', 300);
$errmsg_arr = array();
$errflag = false;
$link;
include ('simple_html_dom.php');


    $base1 = "http://www.mysite.com/get-listing.php";
    $html = file_get_html($base1);      

    $xml .= "<?xml version='1.0' encoding='UTF-8' ?>";
    $xml .= '
<tv generator-info-name="www.testbox.elementfx.com/test">';
    echo $xml;
    $links = $html->find('p[id=links] a');

    foreach ($links as $element) 
    {
      //open each url in each array
      $urls[] = $link->href;
      $url = $urls;
      $data = file_get_html($url);
      echo $data;
    }
  }
?>

我不知道你为什么要将URL保存在一个数组中，因为你似乎只想打开它们，但你可以更改它

$urls[] = $link->href;
$url = $urls;

进入这个

$urls[] = $url = $link->href;

编辑：请注意，通过使用$URL[]=。。。构造将某些内容附加到已存在的数组。可能您想做的是：

foreach ($links as $element) 
{
  //open each url in each array
  $urls = $link->href;
  foreach ($urls as $url) {
      $data = file_get_html($url);
      echo $data;
  }    
}

1$url=$url；2$URL是一个数组。只需将$link->href传递到文件\u get\u html即可。作为旁注，请不要将几个相同的警告消息复制粘贴到SO问题中-这不会增加任何内容。感谢您的建议，请您发布一个示例代码，我需要做哪些更改？@Antonion是的，我需要，我想一次在每个示例代码中打开它们。当我试图使用你发布的代码时，我仍然收到同样的警告。当我在这里获取元素时，如何连接到每个数组的每个url是我使用的代码：//打开每个数组中的每个url$url[]=$url=$links->href$数据=文件\获取\ html$url；回波数据；您能发布var_dump$url；的结果吗@Antonion请看我的第一篇文章，我编辑了这篇文章，把var_dump$url的结果放进去@安东尼安，你看到结果了吗？

foreach ($links as $element) 
{
  //open each url in each array
  $urls = $link->href;
  foreach ($urls as $url) {
      $data = file_get_html($url);
      echo $data;
  }    
}
