php实现断点续传，就需要把大文件分割成多个小文件，然后单个上传。传完后在合并。
│ merge.php –合并文件脚本
│ merge.zip –合并后文件
│ socket.zip –需要分割的文件
│ split.php –分割文件脚本
│
└─split –分割后小文件目录
下面是源码
split.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
//print_r($filelist);
$mergeFileName = ‘merg.zip’;
$mergeFileName = ‘merg.zip’;
unlink($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);
