php實現斷點續傳，就需要把大文件分割成多個小文件，然后單個上傳。傳完后在合并。
│ merge.php –合并文件腳本
│ merge.zip –合并后文件
│ socket.zip –需要分割的文件
│ split.php –分割文件腳本
│
└─split –分割后小文件目錄
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);
