PHP - Arrays

Given two arrays:
$keys = ['name', 'age', 'city'];
$values = ['Alice', 30, 'Paris'];
Which PHP code correctly creates an associative array and then merges it with ['country' => 'France']?

A$assoc = array_combine($keys, $values); $final = array_merge($assoc, ['country' => 'France']);

B$assoc = array_merge($keys, $values); $final = array_combine($assoc, ['country' => 'France']);

C$final = array_combine($keys, $values, ['country' => 'France']);

D$final = array_merge(array_combine($values, $keys), ['country' => 'France']);

Step-by-Step Solution

Solution:

Step 1: Create associative array from keys and values
Use array_combine($keys, $values) to pair keys with values correctly.
Step 2: Merge associative array with another array
Use array_merge to add the 'country' key-value pair to the associative array.
Step 3: Check other options for errors
$assoc = array_merge($keys, $values); $final = array_combine($assoc, ['country' => 'France']); swaps functions incorrectly, C uses wrong parameter count, D swaps keys and values.
Final Answer:
$assoc = array_combine($keys, $values); $final = array_merge($assoc, ['country' => 'France']); -> Option A
Quick Check:
Combine keys-values, then merge extra array = A [OK]

Quick Trick: Combine keys-values first, then merge extra pairs [OK]

Common Mistakes:

Swapping keys and values in array_combine
Trying to combine more than two arrays at once
Using array_merge before array_combine
