关于php curl和curl命令

Php curl返回一些站点的空白页，其中curl命令工作正常

例如：curl www.wikipedia.org生成输出，而php curl提供带有标记的空白页面

您可以使用以下代码执行此操作：

<?php

$fb_page_url = "http://www.wikipedia.org";

/**

$ch = curl_init($fb_page_url);

让你分配$url=www.wikipedia.org；让你分配$url=www.wikipedia.org；通过提供eventtarget和eventargument，您还可以单击任何链接（如果需要）。我想这可能会对你有所帮助。这绝对不是在回答这个问题。。。这看起来就像是将某个curl请求随机复制粘贴到特定页面。我的意思是：为什么curl_setopt$ch，CURLOPT_TIMEOUT，9850；甚至在这里产生影响？op没有报告超时问题，为什么要将其设置得如此之高？通过提供eventtarget和eventargument，您还可以单击任何链接（如果需要）。我想这可能会对你有所帮助。这绝对不是在回答这个问题。。。这看起来就像是将某个curl请求随机复制粘贴到特定页面。我的意思是：为什么curl_setopt$ch，CURLOPT_TIMEOUT，9850；甚至在这里产生影响？op没有报告超时问题，为什么要将其设置得如此之高？
