What are common challenges when using PHP on mobile devices like smartphones or tablets?

Common challenges when using PHP on mobile devices include issues with responsiveness, as PHP is primarily a server-side language and cannot directly interact with the user interface on the client side. To address this, developers often use JavaScript frameworks like jQuery or AngularJS to handle client-side interactions and make the website more mobile-friendly. 

// Example of using jQuery to handle mobile responsiveness in PHP
<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
<script>
  $(document).ready(function(){
    // Add responsive design functionality here
  });
</script>
