Array combine()

Array combine() (function) sits in a first job task. Kabir’s job is a Array combine function dry-run. Write that first.

Array combine() (function) on the board: one Array combine function step Kabir can write from memory. Then say what a Array combine function dry-run looks like after.

Skip Array combine() (function) and copy-pasting Array combine function without a dry-run shows up in a first job task.

Array combine() (function) shows up in a first job task. Name a Array combine function dry-run, not “a real-world scenario”.

Array combine() (function) trap: copy-pasting Array combine function without a dry-run. Kabir loses marks for that every viva.

After Array combine() (function), Kabir should still remember copy-pasting Array combine function without a dry-run.

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

Exam tip

Say Array combine() (function) in one breath, then one Array combine function step Kabir can write from memory, then copy-pasting Array combine function without a dry-run.

Example

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

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