What are potential issues with using the <meta http-equiv="refresh" tag in PHP for a web-based slideshow?

Potential issues with using the <meta http-equiv="refresh" tag in PHP for a web-based slideshow include lack of control over slide timing and potential impact on SEO. To solve this, you can use JavaScript to create a more customizable and SEO-friendly slideshow. 

// PHP code snippet implementing a slideshow using JavaScript instead of meta refresh tag

&lt;!DOCTYPE html&gt;
&lt;html&gt;
&lt;head&gt;
    &lt;title&gt;Slideshow&lt;/title&gt;
    &lt;script&gt;
        var slideIndex = 0;
        showSlides();

        function showSlides() {
            var i;
            var slides = document.getElementsByClassName(&quot;mySlides&quot;);
            for (i = 0; i &lt; slides.length; i++) {
                slides[i].style.display = &quot;none&quot;;
            }
            slideIndex++;
            if (slideIndex &gt; slides.length) {slideIndex = 1}
            slides[slideIndex-1].style.display = &quot;block&quot;;
            setTimeout(showSlides, 2000); // Change slide every 2 seconds
        }
    &lt;/script&gt;
&lt;/head&gt;
&lt;body&gt;

&lt;div class=&quot;slideshow-container&quot;&gt;
