easy to access element of a structure regardless of nesting levels
array_path use '/' as default path seperator,if you want use other character, define ARRAY_PATH_SEPERATOR before include array_path
sample:
<?php
$player = array(
'level' => 10,
'silver' => 20,
'building' => array(
'blacksmith' => array(
'level' => 2,
'store' => array(
'sword' => 2,
),
),
),
'heroes' => array(
array(
'id' => 1,
'name' => 'jack',
'attr' => array(
'str' => 10,
'def' => 20,
),
),
array(
'id' => 2,
'name' => 'jane',
'attr' => array(
'str' => 13,
'def' => 26,
),
),
),
);
array_path_get($player, 'level'); // return 10
array_path_get($player, 'building/blacksmith/level'); // return 2
//combine with any params
array_path_get($player, 'building', 'blacksmith/level'); // return 2
array_path_get($player, 'building/blacksmith', 'level'); // return 2
array_path_get($player, 'building', 'blacksmith', 'level'); // return 2
array_path_get($player, 'heroes', 0, 'attr'); // return array('str' => 10, 'def' => 20)
//last param is the value been set
array_path_set($player, 'heroes/0/attr/str', 15);
array_path_set($player, 'heroes', 0, 'attr', 'str', 15);
array_path_set($player, 'heroes', 2, array('id' => 3));
array_path_unset($player, 'heroes', 1); //this will make heroes node a dict
array_path_walk($player, function($key, $value) {
echo $key . ":" . $value . "\n";
});
//will output as follow:
// level:10
// silver:20
// building:
// heroes/0/id:1
// heroes/0/name:jack
// heroes/0/attr/str:15
// heroes/0/attr/def:20
// heroes/1/id:2
// heroes/1/name:jane
// heroes/1/attr/str:13
// heroes/1/attr/def:26
// heroes/2/id:3
