Array uasort()

Array uasort() (function) sits in a campus project. Farhan’s job is a Array uasort function dry-run. Write that first.

For Array uasort() (function), the PHP runtime is in play. Don’t blame it until you have traced a Array uasort function dry-run.

Without Array uasort() (function), a campus project gets messy and a Array uasort function dry-run is hard to trust.

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

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

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

Viva for Array uasort() (function): what it is → one Array uasort function step Farhan can write from memory → the mistake (skipping the failure case for Array uasort function).

Exam tip

Say Array uasort() (function) in one breath, then one Array uasort function step Farhan can write from memory, then skipping the failure case for Array uasort function.

Example

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

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