What resources or tools can be used to understand PHP tokens and their meanings in code?

To understand PHP tokens and their meanings in code, one can use the PHP Tokenizer extension, which allows for the parsing of PHP code into tokens. Additionally, tools like PHP CodeSniffer can be used to analyze code and identify tokens, providing information on their meanings and usage. PHP documentation also offers a comprehensive list of PHP tokens and their definitions, which can be referenced to better understand the language's syntax. 

// Example code snippet using PHP Tokenizer extension
$code = '<?php echo "Hello, World!";';
$tokens = token_get_all($code);

foreach ($tokens as $token) {
    if (is_array($token)) {
        echo "Token: " . token_name($token[0]) . " => " . $token[1] . PHP_EOL;
    } else {
        echo "Token: " . $token . PHP_EOL;
    }
}
