What alternative method can be used to check for the existence of a file with dynamic paths in PHP?

When dealing with dynamic paths in PHP, the file_exists() function may not work as expected due to the changing nature of the paths. To check for the existence of a file with dynamic paths, you can use the is_file() function along with the realpath() function to resolve the dynamic path to its absolute form before checking if the file exists. 

// Example code to check for the existence of a file with dynamic paths in PHP
$dynamic_path = "path/to/dynamic/file.txt";

$absolute_path = realpath($dynamic_path);

if ($absolute_path && is_file($absolute_path)) {
    echo "File exists at path: " . $absolute_path;
} else {
    echo "File does not exist at path: " . $dynamic_path;
}
