3. If you cannot modify the configuration on the server, use the curl function to replace the file_get_contents function. Of course it is not a simple replacement. The curl function can be used properly only with corresponding parameter configurations.

The curl function is encapsulated as follows:

The code is as follows: Copy code

Function http_request ($ url, $ timeout = 30, $ header = array ()){
If (! Function_exists ('curl _ init ')){
Throw new Exception ('server not install curl ');
$ Ch = curl_init ();
Curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, true );
Curl_setopt ($ ch, CURLOPT_HEADER, true );
Curl_setopt ($ ch, CURLOPT_URL, $ url );
Curl_setopt ($ ch, CURLOPT_TIMEOUT, $ timeout );
If (! Empty ($ header )){
Curl_setopt ($ ch, CURLOPT_HTTPHEADER, $ header );
$ Data = curl_exec ($ ch );
List ($ header, $ data) = explode ("rnrn", $ data );
$ Http_code = curl_getinfo ($ ch, CURLINFO_HTTP_CODE );
If ($ http_code = 301 | $ http_code = 302 ){
$ Matches = array ();
Preg_match ('/Location :(.*?) N/', $ header, $ matches );
$ Url = trim (array_pop ($ matches ));
Curl_setopt ($ ch, CURLOPT_URL, $ url );
Curl_setopt ($ ch, CURLOPT_HEADER, false );
$ Data = curl_exec ($ ch );

If ($ data = false ){
Curl_close ($ ch );
@ Curl_close ($ ch );
Return $ data;
