PHP filesize () In files> 2 GB

Question

I am doing how to get a valid file for s> = 2 GB file in PHP.

Example
Here I check the size of a file that has 3,827,394,560 bytes with the filesize () function:

echo "The file is " . filesize('C:\MyFile.rar') . " bytes.";

Result
This is what it returns:

The file has a size of -467572736 bytes.

PHP Background uses signed integers, which means that the maximum number that it can represent is 2,147,483,647 (+/- 2 GB).
Here it is limited.

Answer 7

To get the correct file size, I often use this piece of code that I wrote a few months ago. My code uses: exec/ com/ statwhere possible. I know its boundaries, but it is a good starting point. The best idea is to use it filesize()on a 64-bit architecture.

<?php

  function showsize($file) {
    if (strtoupper(substr(PHP_OS, 0, 3)) == 'WIN') {
      if (class_exists("COM")) {
        $fsobj = new COM('Scripting.FileSystemObject');
        $f = $fsobj->GetFile(realpath($file));
        $size = $f->Size;
      } else {
        $size = trim(@exec("for %F in (\"" . $file . "\") do @echo %~zF"));
      }
    } elseif (PHP_OS == 'Darwin') {
      $size = trim(@exec("stat -f %z " . $file));
    } else {
      $size = trim(@exec("stat -c %s " . $file));
    }
    if ((!is_numeric($size)) || ($size < 0)) {
      $size = filesize($file);
    }
    if ($size < 1024) {
      echo $size . ' Byte';
    } elseif ($size < 1048576) {

<?php include("php/size.php"); ?>

<?php showsize("files/VeryBigFile.tar"); ?>

Hope this helps.
