How can PHP be used to automatically adjust the layout of images based on their dimensions to create a cohesive design?

When displaying images on a webpage, it's important to ensure a cohesive design by adjusting the layout based on the dimensions of the images. One way to achieve this is by using PHP to dynamically resize images and set their dimensions based on predefined criteria. By calculating the aspect ratio of each image and adjusting its size accordingly, you can create a visually appealing layout that maintains consistency across different image sizes. 

<?php
// Define the maximum width and height for the images
$maxWidth = 300;
$maxHeight = 200;

// Get the dimensions of the image
$image = "image.jpg";
list($width, $height) = getimagesize($image);

// Calculate the aspect ratio
$aspectRatio = $width / $height;

// Determine the new dimensions based on the aspect ratio
if ($width > $maxWidth || $height > $maxHeight) {
    if ($width > $height) {
        $newWidth = $maxWidth;
        $newHeight = $maxWidth / $aspectRatio;
    } else {
        $newHeight = $maxHeight;
        $newWidth = $maxHeight * $aspectRatio;
    }
} else {
    $newWidth = $width;
    $newHeight = $height;
}

// Output the resized image with the new dimensions
echo "<img src='$image' width='$newWidth' height='$newHeight'>";
?>
