What documentation resources can help with understanding and implementing PHP functions for manipulating filenames?

When working with PHP functions for manipulating filenames, it is essential to refer to the official PHP documentation to understand the available functions and their usage. The PHP manual provides detailed explanations, examples, and user-contributed notes that can help in implementing these functions effectively. 

// Example code snippet using PHP functions to manipulate filenames
$filename = "example.txt";
$extension = pathinfo($filename, PATHINFO_EXTENSION);
$filenameWithoutExtension = pathinfo($filename, PATHINFO_FILENAME);

echo "Original Filename: " . $filename . "<br>";
echo "Extension: " . $extension . "<br>";
echo "Filename without Extension: " . $filenameWithoutExtension . "<br>";

$newFilename = "new_" . $filenameWithoutExtension . "_updated." . $extension;
echo "New Filename: " . $newFilename;
