How can absolute file paths be used in PHP to avoid path not found errors?

When working with file paths in PHP, using absolute file paths can help avoid path not found errors by providing the full path from the root directory. This ensures that the file is located regardless of the current working directory. Absolute file paths start with the root directory, such as "/var/www/html/file.txt" instead of just "file.txt". 

$file_path = '/var/www/html/file.txt';
if (file_exists($file_path)) {
    // File exists, proceed with operations
    $file_contents = file_get_contents($file_path);
    echo $file_contents;
} else {
    echo 'File not found';
}
