How important is performance optimization in PHP code, especially when it comes to micro-optimizations like string concatenation for HTML output?

Performance optimization in PHP code is crucial, especially when dealing with micro-optimizations like string concatenation for HTML output. Inefficient string concatenation can lead to unnecessary memory usage and slower processing times, impacting the overall performance of your application. To improve performance, it's recommended to use alternative methods like output buffering or template engines for generating HTML output efficiently. 

<?php
ob_start();
?>
<html>
<head>
    <title>Example Page</title>
</head>
<body>
    <h1>Welcome to our website!</h1>
</body>
</html>
<?php
$html = ob_get_clean();
echo $html;
?>
