Code

Code is a PHP idea you prove with Rohit walking through Code, not with a slogan.

For Code, the PHP runtime is in play. Don’t blame it until you have traced Rohit walking through Code.

Without Code, a campus project gets messy and Rohit walking through Code is hard to trust.

Code shows up in a campus project. Name Rohit walking through Code, not “a real-world scenario”.

If Rohit walking through Code breaks under Code, check skipping the failure case for Code first.

Place Code next to nearby PHP work — one Code step Rohit can write from memory is the link.

Close Code with — “If I skip it, Rohit walking through Code goes wrong like this: skipping the failure case for Code.”

Exam tip

Say Code in one breath, then one Code step Rohit can write from memory, then skipping the failure case for Code.

Example

<?php
// Code
$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";
}

Code: scores array, print avg, then high marks. Say the output.

Short notes

DefCode — Rohit uses it for Rohit walking through Code in a campus project.
RuleCode → one Code step Rohit can write from memory.
RememberCode + the PHP runtime (a campus project).
UseCode in a campus project (Rohit walking through Code).
TrapCode — skipping the failure case for Code.
ExCode → Rohit walking through Code.
