Array flip()

Don’t start Array flip() (function) with jargon. Start with a Array flip function dry-run. That is the whole point.

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

Array flip() (function) exists so Riya can keep a Array flip function dry-run correct in a first job task.

Use Array flip() (function) when a Array flip function dry-run must stay clear. If a simpler PHP step works, use that instead.

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

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

Close Array flip() (function) with: “If I skip it, a Array flip function dry-run goes wrong like this: copy-pasting Array flip function without a dry-run.”

Exam tip

Board: a Array flip function dry-run. Dry-run Array flip() (function). Name the trap: copy-pasting Array flip function without a dry-run.

Example

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

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