Detailed explanation of file segmentation and merge of php breakpoints

When PHP implements breakpoint continuous transmission, it requires dividing large files into multiple small files and uploading them individually. Merge after the transmission.

│ – Merge file scripts
│ – Merged files
│ – Files that need to be split
│ – Segment file script
│
└─split – Small file directory after splitting

Below is the source code

<?php

$fp = fopen("", "rb");
$filesize = 10;
$i = 0;
$no = 1;
while(!feof($fp))
{
  $file = fread($fp, $filesize);

  $fp2 = fopen("./split/".sprintf("%04d",$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 = '';

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);
