What alternative methods can be used to determine the size of a file in PHP, besides using filesize()?

If you cannot use the filesize() function to determine the size of a file in PHP, you can use other methods such as reading the file into memory and then counting the number of bytes, using the stat() function to get the file information, or using the fseek() and ftell() functions to determine the file size. 

// Method 1: Read the file into memory and count the bytes
$file = 'example.txt';
$content = file_get_contents($file);
$fileSize = strlen($content);
echo "File size: $fileSize bytes";

// Method 2: Using the stat() function
$file = 'example.txt';
$fileSize = stat($file)['size'];
echo "File size: $fileSize bytes";

// Method 3: Using fseek() and ftell() functions
$file = 'example.txt';
$handle = fopen($file, 'r');
fseek($handle, 0, SEEK_END);
$fileSize = ftell($handle);
fclose($handle);
echo "File size: $fileSize bytes";
