PHP create API connecting 2 Applications on same server

Imagine 2 Applications running with different mysql-databases on the same server. I need a way to exchange data between both applications. One Application has no permission to access the database of the other application. The exchange is only backend related (automatic stuff), no user interaction needed.

What would be the best and safest way to do this using php?

You could use named pipes - they're well suited for interprocess communication.

http://my.opera.com/zomg/blog/2007/08/29/php-and-named-pipes

You can try it out in the interactive php:

Davids-MacBook-Air:~ dearlbry$ php -a
Interactive shell

php > posix_mkfifo("test-pipe", 0644);
php > $pipe = fopen('test-pipe','r+');
php > print fgets($pipe);

Let that sit there waiting, then open another terminal:

Davids-MacBook-Air:~ dearlbry$ php -a
Interactive shell

php > $pipe = fopen('test-pipe','r+');
php > fwrite($pipe, "Hello World\n");
php > fclose($pipe);

Watch the "Hello World" show up in the first process. Make sure you put in the "\n", as pipes are buffered and the newline signals to flush it.

You could use a RESTful API where by one application could POST and GET data to and from the other.

// From application2.com

$id = $curl->post('http://application1.com/users/save/', array(
    'name' => 'Matt',
    'bio' => 'I am a person.'
));

// $id is generated from a DB insert

$user = $curl->post('http://application1.com/users/bio/', array(
    'id' => $id
));

// $user contains an array or object of information about Matt
