How can PHP developers differentiate between different types of tokens when working with token_get_all?

When working with token_get_all function in PHP, developers can differentiate between different types of tokens by checking the token type using the is_array() function. If the token is an array, it represents a token with additional information, while if it is a string, it represents a simple token. By checking the token type, developers can handle different types of tokens accordingly in their code.

$tokens = token_get_all($code);

foreach ($tokens as $token) {
    if (is_array($token)) {
        // Token with additional information
        $tokenType = $token[0];
        $tokenValue = $token[1];
        // Handle token with additional information
    } else {
        // Simple token
        $tokenValue = $token;
        // Handle simple token
    }
}
