What are some best practices for implementing size limits for images in PHP applications?

When working with image uploads in PHP applications, it's important to implement size limits to prevent users from uploading large files that could potentially slow down the server or cause other issues. One way to do this is by setting a maximum file size limit in the PHP code that handles the image uploads. 

// Set maximum file size limit for image uploads (in bytes)
$maxFileSize = 5242880; // 5 MB

// Check if the uploaded file exceeds the maximum file size limit
if ($_FILES['image']['size'] > $maxFileSize) {
    echo 'Error: File size exceeds the maximum limit of 5 MB.';
    exit;
}

// Continue with the image upload process if the file size is within the limit
// Your image upload code here...
