How can knowledge of the metasprache for PHP syntax benefit developers in creating their own code generators or editors?

Understanding the metasprache for PHP syntax can benefit developers in creating their own code generators or editors by allowing them to parse and manipulate PHP code programmatically. This knowledge enables developers to automate repetitive tasks, generate code templates, and perform complex refactoring operations more efficiently. 

// Example PHP code snippet demonstrating how to parse and manipulate PHP code using the metasprache

$code = '<?php echo "Hello, World!"; ?>';

$tokens = token_get_all($code);

foreach ($tokens as $token) {
    if (is_array($token)) {
        list($id, $text) = $token;
        echo "Token ID: $id, Text: $text\n";
    } else {
        echo "Text: $token\n";
    }
}
