What are some common pitfalls when trying to implement a slideshow feature with PHP on a website?

One common pitfall when implementing a slideshow feature with PHP is not properly handling the transition between images, leading to a choppy or abrupt display. To solve this, you can use JavaScript to create a smooth transition effect when switching between images in the slideshow.

<script>
  var slideIndex = 0;
  showSlides();

  function showSlides() {
    var i;
    var slides = document.getElementsByClassName("mySlides");
    for (i = 0; i < slides.length; i++) {
      slides[i].style.display = "none";  
    }
    slideIndex++;
    if (slideIndex > slides.length) {slideIndex = 1}    
    slides[slideIndex-1].style.display = "block";  
    setTimeout(showSlides, 2000); // Change image every 2 seconds
  }
</script>
