Laravel - Request and Response

A$city = $request->input('user.address.city', 'Unknown');

B$city = $request->get('user')['address']['city'] ?? 'Unknown';

C$city = $request->query('user.address.city') ?: 'Unknown';

D$city = $request->input('user')['address']['city'] ?? 'Unknown';

Step-by-Step Solution

Solution:

Step 1: Use dot notation with input()
Laravel supports dot notation in input() to access nested data safely with a default value.
Step 2: Analyze other options
B uses valid get() but unsafe array access if 'user' missing, C uses query() which only reads URL params, D uses input('user') which may be null leading to array access error.
Final Answer:
$city = $request->input('user.address.city', 'Unknown'); -> Option A
Quick Check:
Use input('nested.key', default) for nested safe access [OK]

Quick Trick: Use input('nested.key', default) for nested values [OK]

Common Mistakes:

Trying to access nested arrays without checking existence
Unsafe manual array access after get('user') or input('user')
Using query() which only reads URL parameters
