Q
What will be the output of the following PHP code?
<?php
$numbers = array(10, 20, 30, 40, 50);
array_pop($numbers);
foreach ($numbers as $number) {
echo $number . ' ';
}
?

Answer & Solution

Answer: Option C
Solution:
The output of the code will be 10 20 30 40 because the array_pop() function removes the last element (50) from the $numbers array. The foreach loop then iterates over the modified array, printing each remaining number, resulting in the output 10 20 30 40.
