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