Are there any potential pitfalls or errors to watch out for when extracting parts of a filename in PHP?

When extracting parts of a filename in PHP, one potential pitfall to watch out for is assuming that the filename will always have a certain structure or format. It's important to handle cases where the filename may not match the expected format, to avoid errors or unexpected behavior. One way to mitigate this risk is to use PHP's built-in functions like pathinfo() or explode() to extract parts of the filename in a more robust and flexible way. 

// Example code snippet using pathinfo() to extract filename parts
$filename = "example_file.jpg";
$file_parts = pathinfo($filename);

$filename_without_extension = $file_parts['filename'];
$extension = $file_parts['extension'];

echo "Filename without extension: " . $filename_without_extension . "\n";
echo "Extension: " . $extension;
