Are there any specific PHP functions that can help with manipulating file paths?

When working with file paths in PHP, it is important to use the correct functions to manipulate them to ensure compatibility across different operating systems. PHP provides several built-in functions that can help with manipulating file paths, such as `dirname()`, `basename()`, `realpath()`, and `pathinfo()`. These functions can be used to extract directory names, file names, resolve symbolic links, and retrieve path information respectively.

// Example of using PHP functions to manipulate file paths
$file_path = '/path/to/file.txt';

// Get the directory name
$directory = dirname($file_path);
echo "Directory: $directory\n";

// Get the base name
$filename = basename($file_path);
echo "Filename: $filename\n";

// Get the real path
$real_path = realpath($file_path);
echo "Real Path: $real_path\n";

// Get path information
$path_info = pathinfo($file_path);
echo "Path Info: ";
print_r($path_info);
