简单示例:

?

split.php

?

<?php
$i    = 0;                               //分割的块编号
$fp   = fopen("abc.wmv","rb");     //要分割的文件
$file = fopen("split_hash.txt","a");     //记录分割的信息的文本文件
while(!feof($fp))
{
        $handle = fopen("abc.wmv.{$i}","wb");
        fwrite($handle,fread($fp,5000000));            //5000000 可以自定义.就是每个所分割的文件大小
        fwrite($file,"qqdjz_002.wmv.{$i}\r\n");
        fclose($handle);
        unset($handle);

foreach($list as $value)
{
<span style="white-space: pre;">	</span>if(!empty($value)) {  
      <span style="white-space: pre;">		</span>$handle = fopen($value,"rb");
