If you can teach foreach Loop using foreach Loop on Meera's board, you know it. If you only know the heading, you don’t.

For foreach Loop, Apache/Nginx is in play. Don’t blame it until you have traced foreach Loop on Meera's board.

Skip foreach Loop and only reciting the name of foreach Loop shows up in a small live site.

Use foreach Loop when foreach Loop on Meera's board must stay clear. If a simpler PHP step works, use that instead.

foreach Loop trap — only reciting the name of foreach Loop. Meera loses marks for that every viva.

foreach Loop is not a lonely heading. Meera ties it to foreach Loop on Meera's board.

Viva for foreach Loop: what it is → one foreach Loop step Meera can write from memory → the mistake (only reciting the name of foreach Loop).

Exam tip

Board: foreach Loop on Meera's board. Dry-run foreach Loop. Name the trap: only reciting the name of foreach Loop.

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