This example describes how to implement HTTP resumable data transfer in PHP. Share it with you for your reference. The specific implementation method is as follows:

<? Php/*** PHP-HTTP resumable upload implementation * @ param string $ path: file path * @ param string $ file: file name * @ return void */function download ($ path, $ file) {$ real = $ path.' http://www.jb51.net/ '. $ File; if (! File_exists ($ real) {return false;} $ size = filesize ($ real); $ size2 = $ size-1; $ range = 0; if (isset ($ _ SERVER ['HTTP _ range']) {header ('HTTP/1.1 206 Partial content'); $ RANGE = str_replace ('= ', '-', $ _ SERVER ['HTTP _ range']); $ RANGE = explode ('-', $ range ); $ range = trim ($ range [1]); header ('content-Length :'. $ size); header ('content-Range: bytes '. $ range. '-'. $ size2 .' http://www.jb51.net/ '. $ Size);} else {header ('content-Length:'. $ size); header ('content-Range: bytes 0-'. $ size2 .' http://www.jb51.net/ '. $ Size);} header ('accenpt-Ranges: bytes '); header ('application/octet-stream'); header ("Cache-control: public "); header ("Pragma: public"); // solves Chinese garbled characters during download in IE. $ ua =$ _ SERVER ['HTTP _ USER_AGENT ']; if (preg_match ('/MSIE/', $ ua) {$ ie_filename = str_replace ('+', '% 20', urlencode ($ file )); header ('content-Dispositon: attachment; filename = '. $ ie_filename);} else {header ('content-Dispositon: attachment; filename = '. $ File) ;}$ fp = fopen ($ real, 'rb + '); fseek ($ fp, $ range); while (! Feof ($ fp) {set_time_limit (0); print (fread ($ fp, 1024); flush (); ob_flush ();} fclose ($ fp );}
