Implode()

Sara only reaches for Implode() (function) when a Implode function dry-run has to stay correct in lab hour.

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

Skip Implode() (function) and copy-pasting Implode function without a dry-run shows up in lab hour.

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

If a Implode function dry-run breaks under Implode() (function), check copy-pasting Implode function without a dry-run first.

Implode() (function) is not a lonely heading. Sara ties it to a Implode function dry-run.

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

Exam tip

Board: a Implode function dry-run. Dry-run Implode() (function). Name the trap: copy-pasting Implode function without a dry-run.

Example

<?php
// Implode()
$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";
}

Implode(): scores array, print avg, then high marks. Say the output.

Short notes

DefImplode() (function) — Sara uses it for a Implode function dry-run in lab hour.
RuleImplode() (function) → one Implode function step Sara can write from memory.
RememberImplode() (function) + Apache/Nginx (lab hour).
UseImplode() (function) in lab hour (a Implode function dry-run).
TrapImplode() (function) — copy-pasting Implode function without a dry-run.
ExImplode() (function) → a Implode function dry-run.
