How to split the merged file by the PHP breakpoint continuation

  This article mainly introduces how to split the file of PHP breakpoint, the need for friends can refer to the following

  Code as follows: <?php  ini_set ("Memory_limit", "50M");/must, according to the actual situation of your environment as large as possible, to prevent errors   ini_set ("Max_execution_ Time ",";  ") the//file_exists () function checks whether a file or directory exists, returns True if it exists, or returns false. The  //fread () function reads files (which are safe for binary files). Fread () reads up to length bytes from file pointer files. The  //filesize () function returns the size (in bytes) of the specified file. The result of this function is cached. Please use Clearstatcache () to clear the cache.   $orgFile = ' fireworks8-chs.exe ';//source file   $cacheFileName = ' vbcache ';//Split temporary file block   function Cutfile ($ FileName, $block) {//split   global $cacheFileName;  if (!file_exists ($fileName)) return false;  $num = 1;& nbsp $file = fopen ($fileName, ' RB ');  while ($content = Fread ($file, $block)) {  $cacheFile = $cacheFileName. $num + + . '. Dat ';  $cfile = fopen ($cacheFile, ' WB ');  fwrite ($cfile, $content);  fclose ($cfile); }  Fclose ($file); }  function Mergefile ($targetFile) {//merge   global $cacheFileName;  $num = 1;  $ File = fopen ($targetFile, ' WB ');  while ($num > 0) {  $cacheFile = $cacheFileName. $num + +. '. Dat ';  if (file_exists ($cacheFile)) {  $cfile = fopen ($cacheFile, ' RB ');  $content = fread ($cfile, files Ize ($cacheFile));  fclose ($cfile);  fwrite ($file, $content); }  else {  $num = -1; }& nbsp }  fclose ($file); } //Call   Cutfile ($orgFile, pow (2,20)); The * POW (2,20) equals the 10M Pow () function returns X's y   mergefile (' Ok.exe '); ?>
