安装

在Linux中编译Yaconf

• Yaconf是一个PECL扩展，简单安装

$ pecl install yaconf

• 或者你可以自己编译

http://pecl.php.net/package/yaconf

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

运行时配置

• 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.

Api

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

bool Yaconf::has(string $name)

示例

配置文件目录

在php.ini里我们设置配置文件目录

yaconf.directory=/tmp/yaconf

INI配置文件

在/tmp/yaconf中设置2个配置文件

foo.ini

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

bar.ini

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

[children:base]
children="set"

运行

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"
  }
}
