Php uses file_get_contents instead of curl instance, curlgetcontents

This example describes how php uses file_get_contents instead of curl. The specific implementation method is as follows:

File_get_contents is rarely used to replace curl, but sometimes you can use file_get_contents instead of curl when the server does not support curl. The following is an example.

'Header' => "Content-type: application/x-www-form-urlencoded ",
'Content' => $ post
)
);
Return file_get_contents ($ url, false, stream_context_create ($ options ));
}

Neither file_get_contents nor curl can be used in php to obtain content.

Simulate header information
<? Php $ opts = array ('http' => array ('method' => "GET", 'header' => "User-Agent :". $ _ SERVER ['HTTP _ USER_AGENT ']. "\ r \ n"); $ context = stream_context_create ($ opts); $ url = dynamic.12306.cn/.20.1_data = file_get_contents ($ url, null, $ context); echo $ data;?> In this way, you can

And POST request, and then the page captures the corresponding needs, when you want to access the second version, send

The request is a GET request. In this case, the parameter must be sent in the past until the tenth page. Php manager available on the Internet
