What potential issues can arise when trying to determine the file size of jpgs in PHP?

One potential issue when trying to determine the file size of JPGs in PHP is that the file size may exceed the maximum integer value that PHP can handle, resulting in inaccurate calculations. To solve this issue, you can use the `filesize()` function in PHP, which returns the size of a file in bytes. 

$filename = 'image.jpg';
$filesize = filesize($filename);
echo "File size of $filename is: $filesize bytes";
