What are some best practices for utilizing the PHP Tokenizer in code analysis?

When utilizing the PHP Tokenizer for code analysis, it is important to follow best practices to ensure accurate and efficient parsing of PHP code. One key practice is to use the `token_get_all()` function to tokenize the PHP code, which returns an array of tokens representing the code. Another best practice is to handle different token types appropriately, such as identifiers, keywords, operators, and literals. Additionally, it is recommended to use the token constants provided by PHP for easier token type identification. 

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

$tokens = token_get_all($code);

foreach ($tokens as $token) {
    if (is_array($token)) {
        $tokenType = token_name($token[0]);
        $tokenValue = $token[1];
        echo "Token Type: $tokenType, Token Value: $tokenValue\n";
    } else {
        echo "Token Value: $token\n";
    }
}
