Q
What will be the output of the following PHP code?
<?php
$arr1 = array('a', 'b', 'c');
$arr2 = array(1, 2, 3);
$result = array_merge($arr1, $arr2);
foreach ($result as $item) {
echo $item . ' ';
}
?

Answer & Solution

Answer: Option A
Solution:
The output of the code will be a b c 1 2 3 because the array_merge() function merges the elements of $arr1 and $arr2 into a single array $result. The foreach loop then iterates over the merged array, printing each item, resulting in the output a b c 1 2 3.
