Are there specific PHP coding practices that can help ensure consistent display of header graphics in different areas of a website?

To ensure consistent display of header graphics in different areas of a website, you can create a PHP function that outputs the header graphic HTML code. This function can be called in various template files to display the header graphic consistently across the site.

function display_header_graphic() {
    // Code to retrieve and display header graphic
    echo '<img src="path/to/header-graphic.jpg" alt="Header Graphic">';
}
```

You can then call this function in your header.php file or any other template file where you want the header graphic to appear:

```php
<?php display_header_graphic(); ?>
