<?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);

<?php$filelist = glob('./split/*socket*.tmp');$filesize = 10;//print_r($filelist);$mergeFileName = 'merg.zip';unlink($mergeFileName);  $fp2 = fopen($mergeFileName,"w+");foreach($filelist as $k => $v){  $fp = fopen($v, "rb");   $content = fread($fp, $filesize);   fwrite($fp2, $content, $filesize);   unset($content);   fclose($fp);   echo $k,"/n";}  fclose($fp2);
