Question

当我这样做时：

if ($html->find(".infobox_v2", 0)->children(1)->children(0)->children(0)->href) {
            echo "infobox";
            infobox();

        }

找不到链接我收到此消息; 致命错误：在非对象上调用成员函数children（）我希望错误，但我想继续运行代码谢谢！

仍然有相同的错误我附上代码：

 try {
       if ($html->find(".infobox_v2", 0)->children(1)->children(0)->children(0)->href) {
          echo "infobox";
          infobox();
       } else if (is_Object($html->find(".thumbinner", 0)) === true && is_Object($html->find(".thumbinner", 0)->children(0)) === true) {
          echo "thumbinner";
          thumbinner(); 
       } else if (is_Object($html->find(".ambox-image", 0))) {
              echo "ambos";
       } else {
          echo "errors<br />";
          $errors++;    
          $nomPersonatge[] = $nomDifunt;
       }
   }catch(Exception $e) {
                }
                echo "Fi ". $i. " part<br />";

感谢您的回答和不便。

如果您的主要概念是从WikiPedia获取所有图像，请使用以下代码（或） WikiPedia API ：

<?php

include('simple_html_dom.php');

set_time_limit(0);

function file_get_safe($link) {
    $content = stream_context_create(
        array(
            "http" => array(
                "timeout" => 30,
                "header"  =>
                    implode("\r\n",
                            array(
                                "Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8",
                                "User-Agent: Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/33.0.1750.154 Safari/537.36",
                                "Accept-Language: en-US,en;q=0.8"
                            )
                    )
            )
        ));
    return @file_get_contents($link, FALSE, $content);
}

function wiki_big_image($image_link) {
    $output = NULL;
    if (filter_var($image_link, FILTER_VALIDATE_URL) !== FALSE) {
        $data = @str_get_html(file_get_safe($image_link));
        if (is_object($data)) {
            $big_image = $data->find("#file a[href*='upload']", 0)->href;
            $big_image = "http:{$big_image}";
            if (filter_var($big_image, FILTER_VALIDATE_URL))
                $output = $big_image;
        }
    }
    return $output;
}

function grab_wiki_images($wiki_word, $big_image = FALSE) {
    $output    = array();
    $big_image = $big_image === TRUE;
    if (is_string($wiki_word) && strlen($wiki_word)) {
        $wiki_word = str_replace(" ", "_", $wiki_word);
        $link      = "http://en.wikipedia.org/wiki/{$wiki_word}";
        $data      = @str_get_html(file_get_contents("wiki.dat"));
        if (is_object($data)) {
            foreach ($data->find("a[href*='\\/wiki\\/File:']") as $elm) {
                $small_image = "http://en.wikipedia.org{$elm->href}";
                if (@preg_match("/\\.(jpeg|jpg|png|svg)$/i", $small_image))
                    $output[] = $big_image ? wiki_big_image($small_image) : $small_image;
                unset($elm);
            }
        }
    }
    return $output;
}

$images = grab_wiki_images("Michael Jackson");

print_r($images);
