How can you troubleshoot issues with including text in a PHP file within an HTML page?

When including text in a PHP file within an HTML page, ensure that the PHP tags are correctly opened and closed. If the text is not displaying, check for any syntax errors in the PHP code that may be preventing the text from being processed. Additionally, make sure that the PHP file is being included properly in the HTML page using the include or require function.

<?php
// Example of including text in a PHP file within an HTML page
$text = "Hello, World!";
?>

<!DOCTYPE html>
<html>
<head>
    <title>PHP Text Inclusion</title>
</head>
<body>
    <h1><?php echo $text; ?></h1>
</body>
</html>
