and (operator) sits in a campus project. Farhan’s job is Farhan walking through and operator. Write that first.

For and (operator), the PHP runtime is in play. Don’t blame it until you have traced Farhan walking through and operator.

Without and (operator), a campus project gets messy and Farhan walking through and operator is hard to trust.

Use and (operator) when Farhan walking through and operator must stay clear. If a simpler PHP step works, use that instead.

and (operator) miss — only reciting the name of and operator. Fix it before you talk about advanced PHP.

After and (operator), Farhan should still remember only reciting the name of and operator.

One breath for and (operator), then Farhan walking through and operator, then only reciting the name of and operator. Sit down.

Exam tip

Say and (operator) in one breath, then one and operator step Farhan can write from memory, then only reciting the name of and operator.

Example

<?php
// and
$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";
}

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

Short notes

Defand (operator) — Farhan uses it for Farhan walking through and operator in a campus project.
Ruleand (operator) → one and operator step Farhan can write from memory.
Rememberand (operator) + the PHP runtime (a campus project).
Useand (operator) in a campus project (Farhan walking through and operator).
Trapand (operator) — only reciting the name of and operator.
Exand (operator) → Farhan walking through and operator.
