What are some best practices for ensuring cross-browser compatibility when developing PHP applications?

Cross-browser compatibility can be ensured by using standardized HTML, CSS, and JavaScript code that is supported by all major browsers. Additionally, testing the application on different browsers and devices can help identify and fix any compatibility issues that may arise. 

<?php
// Example PHP code for detecting the user's browser
$browser = get_browser(null, true);
if($browser['browser'] == 'Chrome'){
    echo 'You are using Chrome browser';
} elseif($browser['browser'] == 'Firefox'){
    echo 'You are using Firefox browser';
} else {
    echo 'You are using a different browser';
}
?>
