Warning: filesize(): stat failed for img.jpg

Question

I am trying to get the file size of an image and I keep getting Warning: filesize(): stat failed for img.jpg

This is what I did:

Answer 1

echo "---- NULL ---------------\n";
$path = null;
echo "File size is: " . filesize($path) . "\n";

echo "---- FILE EXISTS --------\n";
$path = '/home/luca/Scrivania/file_that_exists.jpg';
echo "File size is: " . filesize($path) . "\n";

echo "---- FILE NOT EXISTS ----\n";
$path = 'file/does/not/exists.jpg';
echo "File size is: " . filesize($path) . "\n";

Would result in:

---- NULL ---------------
File size is: 
---- FILE EXISTS --------
File size is: 78953
---- FILE NOT EXISTS ----

Warning: filesize(): stat failed for file/does/not/exists.jpg in /home/luca/Scrivania/test.php on line 13

Call Stack:
    0.0001     642120   1. {main}() /home/luca/Scrivania/test.php:0
    0.0002     642448   2. filesize() /home/luca/Scrivania/test.php:13

This means that your variable

$_FILES['profile']['name'];

is NOT pointing to a valid file location on the SERVER and is instead one among:

1. The file path on the client PC (not on the server) and in that case for sure you have not access to it directly
2. Something that is not a string
3. BUT it is not null (otherwise you simple would have returned null (see first example)

Please next time post valid PHP code.

UPDATE

As Marc B suggested you have to use $_FILES['profile']['tmp_name'];
