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
<?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($filelistas$k=>$v) { $fp=fopen($v,"rb"); $content=fread($fp,$filesize);
fwrite($fp2,$content,$filesize); unset($content); fclose($fp); echo$k,"\n"; } fclose($fp2); |
