建立這個延伸不需要任何外部程式庫。
Beginning with PHP 4.3.0 these functions are enabled by default. For older versions you have to configure and compile PHP with --enable-tokenizer. You can disable tokenizer support with --disable-tokenizer.
Windows 版本的 PHP 已內建此延伸的支援﹐所以你毋須再載入附加的延伸來使用這些功能。
注: Builtin support for tokenizer is available with PHP 4.3.0.
以下的常數由此延伸定義,只在這個延伸被編譯成PHP或實行時期被動態載入時有效。
注: T_ML_COMMENT is not defined in PHP 5. All comments in PHP 5 are of token T_COMMENT.
