    It stands for "token". PHP source code is split into tokens, then interpreted. This process is known as tokenization.

    See this page for a list of PHP tokens.

    You can see for yourself how tokenization works by running token_get_all() on a piece of PHP code.

    The reason why these often come up in basic troubleshooting questions is that the OP has made a syntax error, and the parser encounters an unexpected token as a result of that.
