The tokenizer functions provide an interface to the PHP tokenizer embedded in the Zend Engine. Using these functions you may write your own PHP source analyzing or modification tools without having to deal with the language specification at the lexical level.
See also the appendix about tokens.
Deze functies zijn beschikbaar als onderdeel van de standaard module die altijd beschikbaar is.
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
.
Deze functies worden automatisch ingebouwd in de windows versie van PHP. Er zijn geen extra handelingen nodig om deze functies te gebruiken.
Opmerking: Built-in support for tokenizer is available as of PHP 4.3.0.
When the extension has either been compiled into PHP or dynamically loaded at runtime, the tokens listed in Bijlage S are defined as constants.
Here is a simple example PHP scripts using the tokenizer that will read in a PHP file, strip all comments from the source and print the pure code only.
