Parameterized

Don’t start Parameterized (function) with jargon. Start with Parameterized function on Farhan's board. That is the whole point.

Keep Parameterized (function) small. Farhan should finish Parameterized function on Farhan's board in a few lines, not a 40-line dump.

Without Parameterized (function), a small live site gets messy and Parameterized function on Farhan's board is hard to trust.

Use Parameterized (function) when Parameterized function on Farhan's board must stay clear. If a simpler PHP step works, use that instead.

Don’t do this with Parameterized (function): copy-pasting Parameterized function without a dry-run. Interviewers spot it in ten seconds.

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

One breath for Parameterized (function), then Parameterized function on Farhan's board, then copy-pasting Parameterized function without a dry-run. Sit down.

Exam tip

Board: Parameterized function on Farhan's board. Dry-run Parameterized (function). Name the trap: copy-pasting Parameterized function without a dry-run.

Example

<?php
// Parameterized
$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";
}

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

Short notes

DefParameterized (function) — Farhan uses it for Parameterized function on Farhan's board in a small live site.
RuleParameterized (function) → one Parameterized function step Farhan can write from memory.
RememberParameterized (function) + a .php page (a small live site).
UseParameterized (function) in a small live site (Parameterized function on Farhan's board).
TrapParameterized (function) — copy-pasting Parameterized function without a dry-run.
ExParameterized (function) → Parameterized function on Farhan's board.
