Array rsort()

Array rsort() (function) sits in a viva board. Arun’s job is Arun walking through Array rsort function. Write that first.

Do Array rsort() (function) once by hand. one Array rsort function step Arun can write from memory. Change one input. Say the new result out loud.

Without Array rsort() (function), a viva board gets messy and Arun walking through Array rsort function is hard to trust.

Arun ships Array rsort() (function) in a viva board. That is the use case worth saying.

Array rsort() (function) trap: skipping the failure case for Array rsort function. Arun loses marks for that every viva.

Place Array rsort() (function) next to nearby PHP work — one Array rsort function step Arun can write from memory is the link.

One breath for Array rsort() (function), then Arun walking through Array rsort function, then skipping the failure case for Array rsort function. Sit down.

Exam tip

Board: Arun walking through Array rsort function. Dry-run Array rsort() (function). Name the trap: skipping the failure case for Array rsort function.

Example

<?php
$langs = ["PHP", "JS", "SQL"];
$langs[] = "Python";
foreach ($langs as $i => $lang) {
  echo "$i: $lang\n";
}

Array rsort() — pHP arrays are ordered maps. foreach walks key and value.

Short notes

DefArray rsort() (function) — Arun uses it for Arun walking through Array rsort function in a viva board.
RuleArray rsort() (function) → one Array rsort function step Arun can write from memory.
RememberArray rsort() (function) + the PHP runtime (a viva board).
