Yaconf::get
(PECL yaconf >= 1.0.0)
Yaconf::get — Retrieve a configuration value by name
Description
Retrieves the configuration value stored under
name. Names use dot notation to traverse
nested keys: "app" addresses the whole parsed
app.ini file,
"app.name" a key inside it, and since Yaconf
1.2.0 "users.database.master" a key in the
file database.ini placed in the
users/ sub-directory. The dot notation
supports up to 64 levels of nesting.
Parameters
name
-
The configuration name to look up, using dot notation to
traverse nested keys, for example
"app.name", "app.features.1"
or, since Yaconf 1.2.0, "users.database.master"
for files in sub-directories.
default
-
The value to return when name is not
found. When omitted, null is returned.
Return Values
The stored configuration value, a string or an
array, when name exists;
otherwise the default (or null when no
default was given).
Examples
The examples below assume the following two files placed in the
directory configured with yaconf.directory.
; app.ini
name="shop" ; scalar value
debug=0 ; number
features[]="checkout" ; array entries, both notations
features.1="wishlist"
; users/database.ini, in a sub-directory (Yaconf 1.2.0+)
master="192.168.0.10"
replica="192.168.0.20"
Example #1 Yaconf::get() example
<?php
// fetch a whole parsed file as an array
var_dump(Yaconf::get("app"));
// dot notation traverses nested keys
var_dump(Yaconf::get("app.name")); // string(4) "shop"
var_dump(Yaconf::get("app.features.1")); // string(8) "wishlist"
// since 1.2.0: files in sub-directories are namespaced by the
// directory name
var_dump(Yaconf::get("users.database.master")); // string(12) "192.168.0.10"
// when the key is missing, the default is returned
var_dump(Yaconf::get("app.missing")); // NULL
var_dump(Yaconf::get("app.missing", "fallback")); // string(8) "fallback"
?>
