How can PHP variables be effectively used in conjunction with file creation tasks to ensure proper naming and handling of text files?

When creating text files in PHP, it's important to ensure that the file names are unique and handled properly. One way to achieve this is by using PHP variables to dynamically generate file names based on specific criteria, such as timestamps or user input. This can help prevent overwriting existing files and organize the files in a logical manner. 

// Generate a unique file name using a timestamp
$filename = 'file_' . time() . '.txt';

// Create a new text file with the generated filename
$file = fopen($filename, 'w');
fwrite($file, 'Hello, world!');
fclose($file);

echo "File created successfully with name: $filename";
