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"
