PHP - Array Functions

Given two arrays $names = ['Anna', 'Bob'] and $scores = [85, 92], which code correctly uses array_map to create an array of strings like "Anna scored 85"?

A$results = array_map(fn($name, $score) => "$name scored $score", $names, $scores);

B$results = array_map(fn($name) => "$name scored $score", $names, $scores);

C$results = array_map(fn($name, $score) => '$name scored $score', $names, $scores);

D$results = array_map(fn($name, $score) => $name + ' scored ' + $score, $names, $scores);

Step-by-Step Solution

Solution:

Step 1: Check callback parameters
The callback must accept both name and score to combine them.
Step 2: Verify string interpolation
Double quotes allow variable interpolation, so "$name scored $score" works correctly.
Final Answer:
$results = array_map(fn($name, $score) => "$name scored $score", $names, $scores); -> Option A
Quick Check:
Correct parameters and string interpolation [OK]

Quick Trick: Use double quotes for variable interpolation in strings [OK]

Common Mistakes:

Using single quotes which don't interpolate variables
Missing second parameter in callback
Using + for string concatenation instead of .
