How to safely commit vendor dir with php Composer

Composer is great tool, but sometimes you will need avoid all external dependencies. Sometimes you will need have all source codes in your git repository. Should I commit the dependencies in my vendor directory, and still have all benefits of using Composer? Here are my requirements: - Everything need to be automatically.

I will work on application and my packages together.
I need a simple way how to commit and publish new version of packages.
Workflow need to be simple (mimimum of commands)

How to commit vendor dir?

Remove vendor dir from your .gitignore and add follow lines to root of composer.json

"scripts": {
 "post-update-cmd": ["echo [WARNING] Delete all .git dirs", "rm -rf vendor/**/**/.git"],
 "post-install-cmd": ["echo [WARNING] Delete all .git dirs", "rm -rf vendor/**/**/.git"]
},

That's automatically remove the .git directory of every dependency after the installation or update. You can safely commit everything to your git repo and avoid mistakes with fake git "submodules". Run: composer update and commit everything to your repo. ### How make changes in packages?

When you are using tagged releases (no dev versions) of package then run:

rm -rf vendor/some/package && composer update some/package --prefer-source --no-scripts

For dev versions (dev-master) it's simpler:

rm -rf vendor/some/package && composer update some/package --no-scripts

Now, when you go to vendor/some/package dir it's common git repository - you can make changes, commit and publish new versions of package. But don't forgot run composer update before commit main repo, becouse there is still .git dir in package! ### Disadvantages

Large VCS repository size and diffs when you update code.
Duplication of the history of all your dependencies in your own VCS.
There can be conflicts in commits especially when you work in larger team.
Still not avoid commit .git directory after running composer with --no-scripts param.

Setup email sending from PHP on Mac

First write in terminal: which sendmail wlll return path to sendmail app (in my case /usr/sbin/sendmail). Then open php.ini file and setup:

sendmail_path = /usr/sbin/sendmail -t -i

Create necessary folder and setup postfix permissions:

sudo mkdir -p /Library/Server/Mail/Data/spool
sudo /usr/sbin/postfix set-permissions
sudo /usr/sbin/postfix start

And check if emails will come:

php -r "mail('youremail@domain.com', 'subject', 'message', 'From: <youremail@domain.com>' . PHP_EOL);"

Wordpress - How to get user by metadata

Getting user by field name is easy, #Wordpress have function for that get_user_by. Getting user by his metadata is a little bit complicated. You can found on the Internet some complex procedures how to get user by metadata using WP_Query object. Forget about them! You need prepare correct meta query as array or string and call get_users. Thats all!

function get_user_by_meta($meta_key, $meta_value) {
 return reset(
  get_users(
   array(
    'meta_key' => $meta_key,
    'meta_value' => $meta_value,
    'number' => 1,
    'count_total' => false
   )
  )
 );
}

Wodpress constants for human-readable intervals

Constants for expressing human-readable intervals in new #Wordpress are very useful:

define( 'MINUTE_IN_SECONDS', 60 );
define( 'HOUR_IN_SECONDS',   60 * MINUTE_IN_SECONDS );
define( 'DAY_IN_SECONDS',    24 * HOUR_IN_SECONDS   );
define( 'WEEK_IN_SECONDS',    7 * DAY_IN_SECONDS    );
define( 'YEAR_IN_SECONDS',  365 * DAY_IN_SECONDS    );

Example:

wp_cache_add($key, $data, 'default, 5 * DAY_IN_SECONDS);

Make WordPress globals more accessible

Wordpress using a lot globals variables. These variables are used throughout WordPress code for various reasons. Great example is database connection object wpdb. Here is common example how to use wpdb in some function:

function something() {
  global $wpdb;
  /** @var wpdb $wpdb */
  $wpdb->query('SQL...');
}

It's highly uncomfortable and long! Therefore, I have prepared a simple object which make all global variables much more accesible from anywhere: https://gist.github.com/OzzyCzech/4737518 (PHP 5.3+ only)

function something() {
 Globals::wpdb()->query('SQL...');
}
