get image size before upload image php

Question

I want to know the image size in mb but before ulpload do the same. I have:

$errors =       array();
$image =        $_FILES[\'image\'][\'name\'];
$file_tmp =            


        

Answer 1

Before upload you can check like so:

$file_tmp = $_FILES['image']['tmp_name'];
$size = filesize($file_tmp);

But do you realize you are expecting the image to be less than a kilobyte in your code example?
