What are best practices for linking pages in PHP to display content in specific sections?

When linking pages in PHP to display content in specific sections, it is best practice to use query parameters in the URL to indicate which section of the page to display. This can be achieved by passing a parameter in the URL and then using PHP to check for that parameter and display the corresponding content accordingly. 

```php
<?php
// Check for the section parameter in the URL
if(isset($_GET['section'])) {
    $section = $_GET['section'];

    // Display content based on the section parameter
    switch($section) {
        case 'section1':
            echo "Content for section 1";
            break;
        case 'section2':
            echo "Content for section 2";
            break;
        default:
            echo "Invalid section";
            break;
    }
}
?>
```

In this code snippet, we check if a 'section' parameter is present in the URL using $_GET. We then use a switch statement to determine which section of content to display based on the value of the 'section' parameter. This allows for linking to specific sections within a page using PHP.
