Are there any performance considerations to keep in mind when retrieving file sizes in PHP?

When retrieving file sizes in PHP, it is important to consider the performance implications, especially when dealing with large files or a large number of files. One way to optimize performance is to use the `filesize()` function, which directly retrieves the file size without reading the entire file into memory. This can help prevent memory exhaustion and improve the overall efficiency of your script. 

$file_path = 'path/to/your/file.txt';

// Get the file size using the filesize() function
$file_size = filesize($file_path);

echo "File size: " . $file_size . " bytes";
