The tap() Method in Laravel

One of Laravel's lesser-known yet powerful methods is tap(). This elegant utility allows you to work with a value, perform actions on it, and then return the original value regardless of the callback's return value.

The method signature is simple:

tap($value, $callback = null)

This helper is particularly useful when you want to perform actions on an object and continue chaining methods without breaking the flow. For example:

return tap(new User, function ($user) {
    $user->name = 'Taylor';
    $user->email = 'taylor@example.com';
    $user->save();
});

Instead of assigning the user to a variable, performing operations, and then returning it, tap() handles this cleanly in one expression.

When working with collections, it's invaluable for performing side effects while maintaining chainability:

return $users->filter(function ($user) {
    return $user->isActive();
})->tap(function ($filteredUsers) {
    Log::info('Filtered users: ' . $filteredUsers->count());
})->map(function ($user) {
    return $user->profile;
});

This simple method can significantly clean up your code by reducing variable assignments and improving readability in complex operations.
