What resources or tools can be used to better understand and utilize the metasprache for PHP syntax?

To better understand and utilize the metasprache for PHP syntax, developers can use tools like PHP Parser or PHP-Parser. These tools allow for parsing and analyzing PHP code, providing insights into the structure and syntax of the code.

// Example of using PHP-Parser to parse and analyze PHP code
require_once 'vendor/autoload.php';

use PhpParser\ParserFactory;

$parser = (new ParserFactory)->create(ParserFactory::PREFER_PHP7);
$stmts = $parser->parse($code);

var_dump($stmts);
