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
?
<?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 ($file);echo "ok";?>?
join.php
?
<?php$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);?>?
