This updates php-mode with features to make it more friendly to use with PHP 5.4. It is based on the work of:

1. Turadg Aleahmad
2. Aaron S. Hawley
3. Lennart Borgman
4. Eric James Michael Ritz
5. Michele Bini

And all those mentioned in the ‘Contributors’ section below.

Please email any bugs or feature requests to lobbyjones at gmail dot com or submit them as Issues here on the Github page. Also please include the output of php-mode-version in bug reports.

28 July 2012: I will not be working on any PHP projects in the forseeable future. Therefore I have not worked on adding any new features. However, the project is not dead. I am still accepting bug requests and will try to address them in a timely manner. I also welcome any improvements in functionality from other developers. Updates to php-mode may be infrequent, but I will continue to maintain it as best as possible.

Now php-mode supports syntax highlighting for new keywords which were added as part of PHP 5.4, e.g. those related to traits, such as insteadof. Also supported are the older keywords clone and default.

Every magic constant and predefined constant listed on the official PHP site is included in syntax highlighted.

Traits, interfaces, and namespaces now appear under Imenu listings. Fontification works properly for namespaces as well, so that code like namespace Foo\Bar\Baz no longer looks like a warning. This is also true for namespace aliases, e.g. use <namespace> as <alias>; currently the aliased name is not listed in Imenu, but that will be addressed in the future.

Underscores are treated as ‘symbol constituents’ (in Emacs terminology) so that you can use keys like M-f and M-b to move through the individual parts of a variable name like $foo_bar_baz.

A series of method calls over multiple lines will now be aligned with the -> operator, e.g.:

$object->foo()
       ->bar()
       ->baz();

Nested function calls and array() structures now look better by default (or at least in my opinion). Here is an example of the style:

$results = Post::model()->find(
    array(
        'select'    => 'title',
        'condition' => 'postID=:postID',
        'params'    => array(':postID' => 10),
    )
);

(Note: The alignment of the => operators is not part of these changes.)

Anonymous functions such as

$greet = function($name) { … };

will now appear on Imenu; in this case the name will be $greet.

By customizing the variable php-executable you can enable Flymake mode in order to see warnings and errors in real-time as you write code.

The key command C-c C-f will search the PHP website for documentation on the word under the cursor. However, if you have a local copy of the PHP documentation then php-mode will try searching that documentation first. All you need to do is customize the variable php-manual-path and give it the path to your copy of the documentation. If php-mode cannot find something locally then it will still fallback on searching the PHP website.

The command php-send-region, which is bound to C-c C-r by default, will execute the selected region of PHP code. In conjunction with the Emacs command C-x h you can use this to execute an entire file. Any output will appear in a buffer called *PHP*.

All contributions to php-mode are welcome. But please try to do the following when sending improvements or bug fixes:

1. Add your name to the list of ‘Contributors’ in this README.md file if it is not there already. If you have a Github page then please link your name to it, so people can see your other work. (=^･^=)

2. If your contribution addresses an issue on the Github project page then include a single line like Github-issue: 16 with the appropriate issue number.

3. Make sure to update the constant php-mode-modified.

4. However, please do not modify php-mode-version-number. I will decide what constitutes a bump in the version number.

5. Send me a pull request here on Github. Or if you do not have a Github account then email the patches to me at lobbyjones at gmail dot com. Please try to make sure the patches are acceptable input to the comand git am. Please note that even if you send a pull request it is very likely that I will not simply merge your branch through Github; I prefer to go through commits and cherry-pick them so I can review the commit messages and sign-off on them. You can see which commits I did or did not merge by using the git-cherry command.

If you are fixing a bug related to a Github issue, then first of all, thank you for the help improving php-mode. Second, there is a tests/ directory which contains PHP scripts for each issue (although not all of them). Please consider adding a test script to that directory that documents the expected behavior and provides code that allows others to see if said behavior works properly. Please try to follow the format of the existing tests.

The code for php-mode is covered by the GNU General Public License 3.
