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"; ?> ? ? <?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 $value) { <span style="white-space: pre;"> </span>if(!empty($value)) { <span style="white-space: pre;"> </span>$handle = fopen($value,"rb"); <span style="white-space: pre;"> </span>fwrite($fp,fread($handle,filesize($value))); <span style="white-space: pre;"> </span>fclose($handle); <span style="white-space: pre;"> </span>unset($handle); <span style="white-space: pre;"> </span>} } fclose($fp); ?>? |
