PHP implementation of HTTP breakpoint continuation of the method, PHP implementation of the breakpoint to continue to pass

In this paper, we describe the method of PHP implementing HTTP breakpoint Continuation. Share to everyone for your reference. The implementation method is as follows:

<?php/** * Php-http Breakpoint Continuation Implementation * @param string $path: File path * @param string $file: file name * @return void */function Download ($ Path, $file) {$real = $path. '  /'. $file;  if (!file_exists ($real)) {return false;  } $size = FileSize ($real);  $size 2 = $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. '-'. $size 2. '  /'. $size);    } else {header (' content-length: '. $size); Header (' Content-range:bytes 0-'. $size 2. '  /'. $size);  } header (' Accenpt-ranges:bytes ');  Header (' Application/octet-stream ');  Header ("Cache-control:public");  Header ("Pragma:public");  Solve the problem of Chinese garbled when downloading 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);}
