how to get a hidden file size in php - php

Question

I am uploading image files in PHP but I found out that I was unable to get a file size of some images captured from one mobile device. I can get the file name but not the size so can anyone tell what likely will be the problem or how to fix it to be able to get the file size?
When I check the size in my system its size is in MB while other of my images are in KB.
<?php
if (isset($_FILES["file"]["name"][1]) && !empty($_FILES["file"]["name"])) {
$fileext = ["jpg", "jpeg", "png", "bif", "gif", "bmp"];
for ($i = 1; $i < count($_FILES["file"]["name"]); $i++) {
$name = $_FILES["file"]["name"][$i];
$type = $_FILES["file"]["type"][$i];
$size = $_FILES["file"]["size"][$i];
$path = $_FILES["file"]["tmp_name"][$i];
$ext = end(explode('.', strtolower($name)));
//checking file supported type
if (in_array($ext, $fileext)) {
echo $name . "<br>";
} else {
echo "file type not supported!";
}
}
}
?>

As for the file upload error:
You need to set the value of upload_max_filesize and post_max_size in your php.ini :
; Maximum allowed size for uploaded files.
upload_max_filesize = 40M
; Must be greater than or equal to upload_max_filesize
post_max_size = 40M
After modifying php.ini file(s), you need to restart your HTTP server to use new configuration.
if you'r unable to access your php.ini you can try:
ini_set('upload_max_filesize', '10M');
ini_set('post_max_size', '10M');
ini_set('max_input_time', 300);
ini_set('max_execution_time', 300);
also incressing memory_limit might be usefull..
