What is the role of a parser in PHP and how does it interact with the interpreter?

The parser in PHP is responsible for analyzing the syntax of the code and converting it into a format that the interpreter can understand. It checks for errors and ensures that the code is written correctly before passing it on to the interpreter for execution. 

// Example code snippet demonstrating the role of a parser in PHP
$code = '<?php echo "Hello, World!"; ?>';
$parser = new Parser();
$parser->parse($code);
$interpreter = new Interpreter();
$interpreter->execute($code);
