How can a PHP developer ensure that a lightbox function works properly across different sections of a website?

To ensure that a lightbox function works properly across different sections of a website, a PHP developer can create a reusable function that can be called from any section where the lightbox functionality is needed. This function should handle the opening of the lightbox and display the appropriate content based on the specific context. By centralizing the lightbox functionality in a single function, the developer can ensure consistency and ease of maintenance across the website.

// Reusable function for displaying a lightbox
function displayLightbox($content) {
    // Add code here to display the lightbox with the provided content
}

// Example usage of the displayLightbox function
$lightboxContent = "<img src='image.jpg'>";
displayLightbox($lightboxContent);
