How to get size of an image in PHP?

Question

I want to know how many Kb,Mb an image is by PHP

Answer 1

Use the filesize function:

$size = filesize('image.jpg'); // Returns size in bytes

To find out the size in Kilobytes or Megabytes:

$size_in_kb = round($size / 1024, 2);
$size_in_mb = round($size / (1024 * 1024), 2);
