Is it recommended to separate HTML code with embedded PHP code into a separate file and include it using the include function in PHP?

It is generally recommended to separate HTML code with embedded PHP code into a separate file for better organization and maintainability. This can be achieved by creating a separate PHP file containing the HTML code with embedded PHP, and then including it using the `include` function in PHP.

<?php
// main.php
// This is the main PHP file where you want to include the HTML code with embedded PHP

include 'html_with_php.php';
?>
```

```php
<?php
// html_with_php.php
// This is the separate file containing the HTML code with embedded PHP

echo "<html>";
echo "<head>";
echo "<title>Embedded PHP</title>";
echo "</head>";
echo "<body>";
echo "<h1>Embedded PHP Example</h1>";
echo "<p><?php echo 'Hello, World!'; ?></p>";
echo "</body>";
echo "</html>";
?>
