「Array a b」より「Array c」を作成
コード
$a = array(
"3" => 3,
"42" => 15,
"4" => 22,
"88" => 6,
);
$b = array(
"0" => array(
"id" => 42,
"area" => "東京",
),
"1" => array(
"id" => 88,
"area" => "大阪",
)
);
print_r($a);
print_r($b);
$c = array();
for($i = 0;$i < count($b);$i++){
$c[$b[$i]['id']]['num'] = $a[$b[$i]['id']];
$c[$b[$i]['id']]['area'] = $b[$i]['area'];
}
print_r($c);
foreach($c as $key => $val){
echo $key." ";
}結果

[3] => 3
