我试图创建一个脚本,从网站表中提取文本并通过php显示。当我在这个地址上运行它时:

结果是空的。代码有问题吗?我如何修复/改进它

<?php

  • 因为在foreach中,您使用查找结果
    /html/body/table
    ,所以不应使用完整路径,而应询问:

    $item['titlu']=trim($article->find('/tbody/tr[1]/td/div',0)->纯文本);
    $item['tr2']=trim($article->find('/tbody/tr[2]',0)->纯文本)

  • 等等

  • 为了你的卷曲效果,你需要移动

    $ch=curl_init()


  • 在第一次
    curl\u setopt

    相同的结果之前,是否网页不允许刮削?我已经在其他页面上测试了这个脚本,它可以工作,如果可以的话,我怎么能绕过它呢?这是我在更改代码后收到的结果。以前是空白的<代码>ERTA详细信息:Luctor Commercial Cod Identifications of ERTA 50/01/1150001435/1 Judet Bucuresti Agentia locala Sector 1
    我已更改了4项首次分配。正如你所看到的那样,它们是有结果的。其他的都是黑色的,你能给我发封短信吗?我可能错过了什么。非常抱歉,我忘了:(我补充回答
