array_push()

If you can teach array_push() (function) using Zara walking through array_push function, you know it. If you only know the heading, you don’t.

Keep array_push() (function) small. Zara should finish Zara walking through array_push function in a few lines, not a 40-line dump.

array_push() (function) exists so Zara can keep Zara walking through array_push function correct in a viva board.

array_push() (function) shows up in a viva board. Name Zara walking through array_push function, not “a real-world scenario”.

array_push() (function) miss: copy-pasting array_push function without a dry-run. Fix it before you talk about advanced PHP.

After array_push() (function), Zara should still remember copy-pasting array_push function without a dry-run.

One breath for array_push() (function), then Zara walking through array_push function, then copy-pasting array_push function without a dry-run. Sit down.

Exam tip

For array_push() (function): definition + a viva board + one failure.

Example

<?php
// array_push()
$scores = [80, 90, 70];
$avg = array_sum($scores) / count($scores);
echo "avg=" . number_format($avg, 1) . "\n";
foreach ($scores as $s) {
  if ($s >= 80) echo "high: $s\n";
}

array_push(): scores array, print avg, then high marks. Say the output.

Short notes

Defarray_push() (function) — Zara uses it for Zara walking through array_push function in a viva board.
Rulearray_push() (function) → one array_push function step Zara can write from memory.
Rememberarray_push() (function) + a .php page (a viva board).
Usearray_push() (function) in a viva board (Zara walking through array_push function).
Traparray_push() (function) — copy-pasting array_push function without a dry-run.
Exarray_push() (function) → Zara walking through array_push function.
