$data = array('s'=>1, 's2'=>2, 's3'=>3);
$lrn_tool_array_picker = new lrn_tool_array_picker();

//[ENG]Simple method, only return specific index value from array
//[CHS]简单的获取某些索引
$result = $lrn_tool_array_picker->by_index($data, 's,s3');
var_export($result);

//[ENG]Simple method, exclude specific index value from array
//[CHS]简单的排除某些索引
$result2 = $lrn_tool_array_picker->exclude_index($data, 's,s3');
var_export($result2);

//[ENG]Exclude or return specific index value from array by rule
//[CHS]根据某些规则获取某些索引值
/*
[ENG]rules array or string. If it is string, use and delimiter(&) between rule.
Format of each rule:
    [path to array, delimited by "/". If next path is circular array or want to match any name of index, use "*" instead]/(_return|_return_exclude)=xx,xx,xx,xx,xx

[CHS]规则组合。如果不是数组，规则之间请使用半角&连接。
每条规则格式如下：
    [数组路径，索引名之间使用/分割。如果是循环数组、或匹配任意数组索引键，请使用*]/(_return|_return_exclude)=xx,xx,xx,xx,xx
