$a= [
['id'=>1,'age'=>12],
['id'=>2,'age'=>13],
['id'=>3,'age'=>15]
];$b= [
['id'=>1,'money'=>100],
['id'=>3,'money'=>400],
['id'=>2,'money'=>200]
];怎么按照id值匹配合并到一個數(shù)組中，形成這樣。$c=[
['id'=>1,'age'=>12,'money'=>100],
['id'=>2,'age'=>13,'money'=>200],
['id'=>3,'age'=>15,'money'=>400]
];

$a = [
['id' => 1, 'age' => 12],
['id' => 2, 'age' => 13],
['id' => 3, 'age' => 15]
];
$b = [
['id' => 1, 'money' => 100],
['id' => 2, 'money' => 200],
['id' => 3, 'money' => 400],
];
$c = [];foreach ($a as $_a) {
$_c = $_a; foreach ($b as $_b) { if ($_a['id'] === $_b['id']) {
$_c['money'] = $_b['money'];
}
}
$c[] = $_c;
}
print_r($c);
