Array current()

Array current() (function) sits in lab hour. Neha’s job is Neha walking through Array current function. Write that first.

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

Array current() (function) exists so Neha can keep Neha walking through Array current function correct in lab hour.

Array current() (function) shows up in lab hour. Name Neha walking through Array current function, not “a real-world scenario”.

If Neha walking through Array current function breaks under Array current() (function), check copy-pasting Array current function without a dry-run first.

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

Viva for Array current() (function): what it is → one Array current function step Neha can write from memory → the mistake (copy-pasting Array current function without a dry-run).

Exam tip

Board: Neha walking through Array current function. Dry-run Array current() (function). Name the trap: copy-pasting Array current function without a dry-run.

Example

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

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