How can i format a file size using php?

August 31, 2023

I have a form where i am uploading a file after successfully file uploaded i want to show a size of each file with KB, MB, GB depends on the file size.

Like this

<div class="d-flex align-items-center gap-3">
  <img src="{{asset('images/icons/file-icon.svg')}}" alt="" style="width: 70px;height: 70px;border-radius: 10px;">
  <div>
    <p class="font-weight-bold m-0 text-primary-dark">{{ $media->name }}</p>
    <p class="m-0 font-weight-bold text-primary-dark">{{ formatFileSize($media->size) }}</p>
  </div>
</div>

I have create a function in which i am sending a size like this in my blade

{{ formatFileSize($media->size) }}

this should give me a proper format with the unit

>Solution :

You can acheive this by using a helper function like this

function formatFileSize($size): string
{
  $units = ['B', 'KB', 'MB', 'GB', 'TB'];
  $base = 1024;
  $unitIndex = 0;

  while ($size >= $base && $unitIndex < count($units) - 1) {
    $size /= $base;
    $unitIndex++;
  }

  return round($size, 2) . ' ' . $units[$unitIndex];
}
