Feature Guide

Variable Expanding

myconfig.ini:

db_driver = "mysql"
db_host   = "localhost"
db_name   = "my_database"
db_dsn    = "[db_driver]:host=[db_host];dbname=[db_name]"

myapp.php:

$c = new Container('myconfig.ini');
echo $c->db_dsn; //mysql:host=localhost;dbname=my_database

Note that this works only for variables without ini [sections].

Sequences

myconfig.ini:

allowed_users = [foo,bar,baz]

myapp.php:

$c = new Container('myconfig.ini');
print_r($c->allowed_users); //array('foo', 'bar', 'baz')

Variable expanding also works on sequences. You can express something like this:

myconfig.ini:

admin_user = foo
allowed_users = [[admin_user],bar,baz]

myapp.php:

$c = new Container('myconfig.ini');
print_r($c->allowed_users); //array('foo', 'bar', 'baz')

Constant Evaluation

myconfig.ini:

error_mode = PDO::ERRMODE_EXCEPTION

Needless to say that this would work on sequences too.

Instances

Using sections

myconfig.ini:

[something stdClass]

myapp.php:

$c = new Container('myconfig.ini');
echo get_class($c->something); //stdClass

Using names

myconfig.ini:

date DateTime = now

myapp.php:

$c = new Container('myconfig.ini');
echo get_class($c->something); //DateTime

Callbacks

myconfig.ini:

db_driver = "mysql"
db_host   = "localhost"
db_name   = "my_database"
db_user   = "my_user"
db_pass   = "my_pass"
db_dsn    = "[db_driver]:host=[db_host];dbname=[db_name]"

myapp.php:

$c = new Container('myconfig.ini');
$c->connection = function() use($c) {
    return new PDO($c->db_dsn, $c->db_user, $c->db_pass);
};
echo get_class($c->connection); //PDO

Instance Passing

myconfig.ini:

[myClass DateTime]

[anotherClass stdClass]
myProperty = [myClass]

myapp.php:

$c = new Container('myconfig.ini');
echo get_class($c->myClass); //DateTime
echo get_class($c->anotherClass); //stdClass
echo get_class($c->myClass->myProperty); //DateTime

Obviously, this works on sequences too.

Instance Constructor Parameters

Parameter names by reflection:

myconfig.ini:

[connection PDO]
dsn      = "mysql:host=localhost;dbname=my_database"
username = "my_user"
password = "my_pass"

Method call by sequence:

myconfig.ini:

[connection PDO]
__construct = ["mysql:host=localhost;dbname=my_database", "my_user", "my_pass"]

Using Names and Sequences:

myconfig.ini:

connection PDO = ["mysql:host=localhost;dbname=my_database", "my_user", "my_pass"]

Instantiation by Static Factory Methods

myconfig.ini:

[y2k DateTime]
createFromFormat[] = [Y-m-d H:i:s, 2000-01-01 00:00:01]

Instance Method Calls

myconfig.ini:

[connection PDO]
dsn             = "mysql:host=localhost;dbname=my_database"
username        = "my_user"
password        = "my_pass"
setAttribute    = [PDO::ATTR_ERRMODE, PDO::ATTR_EXCEPTION]
exec[]          = "SET NAMES UTF-8"

Instance Properties

myconfig.ini:

[something stdClass]
foo = "bar"
