We'd love your help in improving, correcting, adding to the specification. Please file an issue or submit a pull request.
The grammar listings and table of contents of the specification are automatically
generated. If you want to change the grammar, you need to modify the respective
<!--GRAMMAR block and run tools/grammar.php to regenerate the rendered listings.
If you add or change headings, you need to regenerate the TOC using tools/toc.php.
Additionally tools/check_refs.php can be run to verify that all cross-references
are valid.
To combine these three steps you can instead execute tools/pre-commit. To
automatically run it on every commit, create a symlink in the .git/hooks directory:
ln -s -f tools/pre-commit .git/hooks/pre-commitAny contribution you provide to the Specification for PHP must adhere to the same license as stated in the LICENSE.
