What are some potential pitfalls of using lines of code as a basis for measuring work in a PHP project?

Measuring work in a PHP project based solely on lines of code can be misleading as it does not account for the quality or complexity of the code. Instead, consider using more meaningful metrics such as functionality completed, user stories implemented, or bugs fixed. This will provide a more accurate representation of progress and productivity in the project.

// Example of tracking work based on functionality completed
$functionalityCompleted = [
    'login' => true,
    'registration' => true,
    'profile' => false,
    'search' => true
];

$completedFunctionalityCount = array_count_values($functionalityCompleted)[true];
echo "Functionality completed: $completedFunctionalityCount out of " . count($functionalityCompleted);
