Also dropped test_helpers in favor of uopz.

-This is an updated version of the php.vim syntax file distributed with VIM. The list of PHP constants, functions, and classes was updated to be current with PHP 5.3. Many new classes were added in the 5.2 branch and the distributed version only covers up to 5.1.4. In addition I simplified the file, removing several sections that are not often used (at least by me) such as automatic folding of all control structures and ASP tags support. I also removed several switches designed for b/c with VIM 5.X and 6.X. As an addition I have included the PHP file I used to generate the constant, function, class list. It uses reflection to mine out these items from your PHP installation and generate part of the php.vim script. Before running open up the file and adjust the output file location and the list of extensions to generate syntax for. Then run "php php_vimgen.php" from your shell.

+# php.vim
+
+This project is a fork of [php.vim][StanAngeloff] which is an improved version
+of [php.vim--Garvin][garvin] which in turn is an update of the
+[php.vim][php-vim] script which in turn is an updated version of the php.vim
+syntax file distributed with Vim.
+
+The point of this fork is to embrace the latest and greatest PHP has to offer
+and constantly update against the latest PHP release.
+
+Last updated against **5.5.17**
+
+## Improvements
+
+- Spell checking was enabled in strings and comments (both single and
+  multi-line).
+- Spell checking was enabled in heredocs, e.g., `<<<EOD`.
+- The PHP built-in and extension-provided functions list was updated for
+  PHP 5.3.
+- Compatibility with [html5.vim][html5].
+- Support for not-so-common extensions was turned off, e.g., `mssql_*`.
+- Basic support for PHP 5.4 syntax was added.
+- Support was added for PHP 5.5.7
+- New modules added: memcache, memcached, redis, test_helpers and xdebug
+- Support for static classes and docblock parameters (patched by @kris89)
+
+## Customising
+
+A script `update_syntax.php` is provided to re-generate the syntax file.
+A single variable `$allowed_extensions` can be customised to
+[turn on/off][defaults] certain extensions.
+
+When re-generating the syntax file, you must have allowed extensions
+installed.

+"  - A double-quoted string like this:

+ * This script works by loading up PHP extensions and using reflection to pull

+ * extensions below are ones included with PHP 5.3 source code. The ones
+ * commented out depend on an external library being installed, are Unix
+ * specific, or just not commonly used.
+ *
+ * Add, comment, or uncomment to fit your needs or particular PHP installation.
+ * Remember that some of these extensions are likely shared extensions and must
+ * be enabled in your php.ini file.
+ *
+ * NOTE: mysqlnd is not included because it exposes no functions, classes, or
+ * constants. The pdo_* extensions are not included in the list because they do
+ * not expose any functions, classes, or constants themselves. The constants
+ * and methods specific to that driver are exposed though the PDO extension
+ * itself. The pdo_* extensions must still be enabled (compiled in or loaded as
+ * shared) for these constants to show up.
