说明

public static mixed Yaconf::get ( string $name [, mixed $default_value = NULL ] )

参数

name: Configuration key, the key looks like "filename.key", or "filename.sectionName,key".
default_value: if the key doesn't exists, Yaconf::get will return this as result.

返回值

Returns configuration result(string or array) if the key exists, return default_value if not.

范例

Example #1 INI()example

;filenmame foo.ini, placed in directory which is yaconf.directoy
[SectionA]
;key value pair
key=val
;hash[a]=val
hash.a=val
;arr[0]=val
arr.0=val
;or
arr[]=val

;SectionB inherits SectionA
[SectionB:SectionA]
;override configuration key in SectionA
key=new_val

以上例程的输出类似于：

php7 -r 'var_dump(Yaconf::get("foo.SectionA.key"));'
//string(3) "val"

php7 -r 'var_dump(Yaconf::get("foo.SectionB.key"));'
//string(7) "new_val"

php7 -r 'var_dump(Yaconf::get("foo")["SectionA"]["hash"]);'
//array(1)
