合并二进制文件:PHP大文件存储示例，各种文件分割和合并(二进制分割与合并)

简单示例：

split.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);
$i++;
}
fclose ($fp);
fclose ($file);
echo "ok";
?>
join.php
$mov = file_get_contents("abc.txt"); //读取分割文件的信息
$list = explode("\r\n",$mov);
$fp = fopen("split.wmv","ab"); //合并后的文件名
foreach($list as $value)
{
if(!empty($value)) {
$handle = fopen($value,"rb");
fwrite($fp,fread($handle,filesize($value)));
fclose($handle);
unset($handle);
}
}
fclose($fp);
?>
