Answer / Rajesh Srivastava
"array_pop() removes the last element from an array and returns it, while array_push() adds one or more elements to the end of an array. For example:
1. $arr = [1, 2, 3];
2. $lastElement = array_pop($arr); echo $lastElement; // Outputs '3' and $arr contains (1, 2)
3. array_push($arr, 4, 5); echo implode(', ', $arr); // Outputs '1, 2, 4, 5'"
