object(simpleXMLElement) = simplexml_load_string(xmlchar)

xml文字列を作成し、その文字列をsimplexml_load_string()関数で、オブジェクトに代入。
そのオブジェクトを展開することで、xmlデータを取得できる。

無名関数とは?

名前付けされずに定義された関数のこと

<?php

$pension = array(
	"こだわり個人年金"=>'1.186',
	"年金かけはし"=>'1.063',
	"たのしみワンダフル"=>'1.081'
);

print_r(array_map(function($a){$pay = 500;return $a*$pay;}, $pension));

Array ( [こだわり個人年金] => 593 [年金かけはし] => 531.5 [たのしみワンダフル] => 540.5 )

array_filter

配列の値に閾値を設けてフィルタリングする。

<?php

$track = array(
	"みずほFG"=> '2.1',
	"三菱UFJ"=> '3.6',
	"ティアック"=> '0',
	"ランド"=> '0',
	"富士通"=> '-1.0',
	"住友化"=> '22',
	"日産自"=> '2.5',
	"アカツキ" => '1.2'
);

$rate = 1;

$filter_func = function ($value) use ($rate) {
	return ($value >= $rate);
};

$result = array_filter($track, $filter_func);

arsort($result);
var_dump($result);

array(5) { [“住友化”]=> string(2) “22” [“三菱UFJ”]=> string(3) “3.6” [“日産自”]=> string(3) “2.5” [“みずほFG”]=> string(3) “2.1” [“アカツキ”]=> string(3) “1.2” }

$rate = 2の時
array(4) { [“住友化”]=> string(2) “22” [“三菱UFJ”]=> string(3) “3.6” [“日産自”]=> string(3) “2.5” [“みずほFG”]=> string(3) “2.1” }

SORT_NUMERIC, SORT_STRING

並び替えを数値としてするか文字列としてするか支持するためのオプションです。

<?php

$track = array(
	"みずほFG"=> '2.1',
	"三菱UFJ"=> '3.6',
	"ティアック"=> '0',
	"ランド"=> '0',
