What role does the Modulo-Operator play in determining when to insert a line break after a certain number of images displayed on a webpage using PHP?
The Modulo-Operator is used to determine when to insert a line break after a certain number of images displayed on a webpage in PHP. By using the Modulo-Operator with a specific number (e.g., 3) and checking if the current image index is divisible by that number, we can insert a line break to create a grid-like layout for the images.
<?php
$images = ["image1.jpg", "image2.jpg", "image3.jpg", "image4.jpg", "image5.jpg"];
foreach ($images as $index => $image) {
echo '<img src="' . $image . '" alt="Image ' . ($index + 1) . '">';
if (($index + 1) % 3 === 0) {
echo '<br>';
}
}
?>
