php斷點續傳之檔案分割合并執行個體詳解

這篇文章主要為大家詳細介紹了php斷點續傳之檔案分割合并，具有一定的參考價值，感興趣的小夥伴們可以參考一下

php實現斷點續傳，就需要把大檔案分割成多個小檔案，然後單個上傳。傳完後在合并。

│ merge.php –合并檔案指令碼
│ merge.zip –合并後檔案
│ socket.zip –需要分割的檔案
│ split.php –分割檔案指令碼
│
└─split –分割後小檔案目錄

下面是源碼

split.php

<?php$fp = fopen("socket.zip", "rb");$filesize = 10;$i = 0;$no = 1;while(!feof($fp)){  $file = fread($fp, $filesize);  $fp2 = fopen("./split/socket.port".sprintf("%04d",$no).".".$i."-".($i+$filesize).".tmp", "wb");  fwrite($fp2, $file, $filesize);  fclose($fp2);  $i+=$filesize+1;$no++;}fclose($fp);

merge.php

<?php$filelist = glob('./split/*socket*.tmp');$filesize = 10;//print_r($filelist);$mergeFileName = 'merg.zip';unlink($mergeFileName);  $fp2 = fopen($mergeFileName,"w+");foreach($filelist as $k => $v){  $fp = fopen($v, "rb");   $content = fread($fp, $filesize);   fwrite($fp2, $content, $filesize);   unset($content);   fclose($fp);   echo $k,"\n";}  fclose($fp2);
