PHP - Array Functions

Which of the following is the correct syntax to pad an array $arr to size 5 with the value 0 using array_pad?

A$padded = array_pad($arr, 5);

B$padded = array_pad(5, $arr, 0);

C$padded = array_pad($arr, 5, 0);

D$padded = array_pad($arr, 0, 5);

Step-by-Step Solution

Solution:

Step 1: Recall array_pad syntax
The correct syntax is array_pad(array, size, value), where the first argument is the array, second is the desired size, third is the padding value.
Step 2: Check each option
$padded = array_pad($arr, 5, 0); matches the correct order and arguments. Options B and C have wrong argument order. $padded = array_pad($arr, 5); misses the padding value.
Final Answer:
$padded = array_pad($arr, 5, 0); -> Option C
Quick Check:
array_pad(array, size, value) correct order [OK]

Quick Trick: Remember: array_pad(array, size, value) [OK]
