WeChat development-php download network image problems, the local test is successful, the files downloaded from the server are only more than 100 bytes

{Code...} both of the above methods can be tested locally, but put on the server, the downloaded images are only more than 100 bytes, and the image cannot be opened. This method is used to obtain images from the server. Is it caused by the related settings in php. ini? Which settings can be modified...

Function geturlimg ($ url, $ filename = "") {if (! CreateDirs (dirname ($ filename) {die ('Folder cannot be created ');} if (! $ Url) die ('no url'); ob_start (); readfile ($ url); $ img = ob_get_contents (); ob_end_clean (); $ size = strlen ($ img); if ($ size) {$ fp2 = @ fopen ($ filename, "a"); fwrite ($ fp2, $ img ); fclose ($ fp2); return $ filename;} else return false;} function getUrlImg3 ($ url, $ filename = "") {if (! CreateDirs (dirname ($ filename) {die ('Folder cannot be created ');} if (! $ Url) die ('no url'); $ ch = curl_init ($ url); curl_setopt ($ ch, CURLOPT_HEADER, 0); curl_setopt ($ ch, CURLOPT_NOBODY, 0 ); // only the body header curl_setopt ($ ch, CURLOPT_SSL_VERIFYPEER, FALSE); curl_setopt ($ ch, success, FALSE); curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, 1 ); $ package = curl_exec ($ ch); $ httpinfo = curl_getinfo ($ ch); curl_close ($ ch); $ imageAll = array_merge (array ('header' => $ httpinfo ), arr Ay ('body' => $ package); // The upper half is download, and the lower half is save if ($ package) {$ local_file = fopen ($ filename, 'w '); if (false! ==$ Local_file) {if (false! = Fwrite ($ local_file, $ package) {fclose ($ local_file); return true ;}} return false ;}

The above two methods can be tested locally, but they can be put on the server. The downloaded images only contain more than 100 bytes, and the images cannot be opened. This method is used to obtain images from the server. Is it caused by the related settings in php. ini? Which settings can be modified?

This problem has been disabled because I updated the access_token during local debugging, And the token cached on the server is useless, update the server token.
