How can PHP developers ensure cross-browser compatibility when implementing progress bars?

To ensure cross-browser compatibility when implementing progress bars in PHP, developers can use CSS for styling and JavaScript for updating the progress bar dynamically. By using CSS properties that are supported across different browsers and JavaScript functions that handle the progress updates uniformly, developers can create a consistent user experience regardless of the browser being used. 

<!DOCTYPE html>
<html>
<head>
    <style>
        .progress {
            width: 100%;
            background-color: #f1f1f1;
        }

        .progress-bar {
            width: 0%;
            height: 30px;
            background-color: #4caf50;
            text-align: center;
            line-height: 30px;
            color: white;
        }
    </style>
</head>
<body>

<div class="progress">
    <div class="progress-bar" id="progress-bar">0%</div>
</div>

<script>
    var progressBar = document.getElementById('progress-bar');
    var width = 0;
    var interval = setInterval(updateProgress, 1000);

    function updateProgress() {
        if (width >= 100) {
            clearInterval(interval);
        } else {
            width += 10;
            progressBar.style.width = width + '%';
            progressBar.innerHTML = width + '%';
        }
    }
</script>

</body>
