#Yaconf - Yet Another Configurations Container

A PHP Persistent Configurations Container

Requirement

• PHP 7+

Introduction

Yaconf is a configurations container, it parses ini files, and store the result in PHP when PHP is started.

###Features

• Fast, Light
• Zero-copy while accesses configurations
• Support sections, sections inheritance
• Configurations reload automatically after changed

Install

Compile Yaconf in Linux

Yaconf is an PECL extension, thus you can simply install it by:

Or you can compile it by your self:

$ /path/to/php7/bin/phpize $ ./configure --with-php-config=/path/to/php7/bin/php-config $ make && make install

### Runtime Configure

- yaconf.directory    

path to directory which all ini configuration files are placed in

- yaconf.check_delay  

in which interval Yaconf will detect ini file's change(by directory's mtime), if it is set to zero, you have to restart php to reloading configurations.

### APIs

#### mixed Yaconf::get(string $name, mixed $default = NULL)
#### bool  Yaconf::has(string $name)

### Example

#### Directory
 
   Assuming we place all configurations files in /tmp/yaconf/, thus we added this into php.ini

yaconf.directory=/tmp/yaconf

#### INI Files

   Assuming there are two files in /tmp/yaconf

foo.ini
````ini
name="yaconf"
year=2015
features[]="fast"
features.1="light"
features.plus="zero-copy"
features.constant=PHP_VERSION
features.env=${HOME}

and bar.ini

[base]
parent="yaconf"
children="NULL"

[children:base]
children="set"

Run

lets access the configurations

foo.ini

php7 -r 'var_dump(Yaconf::get("foo"));'
/*
array(3) {
  ["name"]=>
  string(6) "yaconf"
  ["year"]=>
  string(4) "2015"
  ["features"]=>
  array(5) {
    [0]=>
    string(4) "fast"
    [1]=>
    string(5) "light"
    ["plus"]=>
    string(9) "zero-copy"
    ["constant"]=>
    string(9) "7.0.0-dev"
	["env"] =>
	string(16) "/home/huixinchen"
  }
}
*/

As you can see, Yaconf supports string, map(array), ini, env variable and PHP constants.

you can also access configurations like this:

php7 -r 'var_dump(Yaconf::get("foo.name"));'
//string(6) "yaconf"

php7 -r 'var_dump(Yaconf::get("foo.features.1"));'
//string(5) "light"

php7 -r 'var_dump(Yaconf::get("foo.features")["plus"]);'
//string(9) "zero-copy"

bar.ini

Now lets see the sections and sections inheritance:

php7 -r 'var_dump(Yaconf::get("bar"));'
/*
array(2) {
  ["base"]=>
  array(2) {
    ["parent"]=>
    string(6) "yaconf"
    ["children"]=>
    string(4) "NULL"
  }
  ["children"]=>
  array(2) {
    ["parent"]=>
    string(6) "yaconf"
    ["children"]=>
    string(3) "set"
  }
}
*/

Children section has inherited values in base sections, and children is able to override the values they want.
