What is the difference between an absolute path and a URL in PHP file handling?

An absolute path in PHP file handling refers to the complete path of a file on the server's filesystem, starting from the root directory. On the other hand, a URL is a web address that specifies the location of a resource on the internet. When working with file handling in PHP, it's important to distinguish between absolute paths and URLs to ensure proper file manipulation and access. 

// Absolute path example
$absolutePath = '/var/www/html/myfile.txt';

// URL example
$url = 'http://www.example.com/myfile.txt';
