What are the advantages of using absolute paths over relative paths in PHP?

When working with file paths in PHP, using absolute paths is preferred over relative paths because absolute paths provide a fixed reference point from the root directory of the file system. This ensures that the file will be located correctly regardless of the current working directory or context of the script. Relative paths can be ambiguous and may lead to errors if the script is executed from a different directory.

// Absolute path example
$absolutePath = '/var/www/html/project/file.txt';
file_get_contents($absolutePath);
