PHP Token names with values

This is a list of all PHP 8.0 tokens and their represented values in decimal and hexadecimal. The list exists in the php.net site here https://www.php.net/manual/en/tokens.php but there are no values because these values may change for new releases. When writing token parsing code, we need token names and values, and I don't want to dig into the source code to get the values.

Beware that many, if not all values, may be different along version; PHP 7 may not have the same values with PHP 8. Always use the constants, this is just for reference mainly for debugging.
