二维数组根据相同值组成新数组？
旧数组：
$orders=array(
array(
"ordersn"=>'2019564842348',
"proName"=>'拖鞋',
"name"=>'张三',
"phone"=>"1800952442",
"proNum"=>2,
"proPrice"=>35.85
),
array(
"ordersn"=>'2019564842348',
"proName"=>'棉签',
"name"=>'张三',
"phone"=>"1800952442",
"proNum"=>1,
"proPrice"=>12
),
array(
"ordersn"=>'25451548412487',
"proName"=>'电脑',
"name"=>'李四',
"phone"=>"1564845487",
"proNum"=>1,
"proPrice"=>4600
),
);
如何通过相同的ordersn组装成新数组:
$orders=array( array( "ordersn"=>'2019564842348', "product"=>array( array( "proName"=>'拖鞋', "proNum"=>2, "proPrice"=>35.85 ), array( "proName"=>'棉签', "proNum"=>1, "proPrice"=>12 ), ), "name"=>'张三', "phone"=>'1800952442' ), array( "ordersn"=>'25451548412487', "product"=>array( array( "proName"=>'电脑', "proNum"=>1, "proPrice"=>4600 ), ), "name"=>'李四', "phpone"=>"1564845487", ), );
$orders=array(
array(
"ordersn"=>'2019564842348',
"proName"=>'拖鞋',
"name"=>'张三',
"phone"=>"1800952442",
"proNum"=>2,
"proPrice"=>35.85
),
array(
"ordersn"=>'2019564842348',
"proName"=>'棉签',
"name"=>'张三',
"phone"=>"1800952442",
"proNum"=>1,
"proPrice"=>12
),
array(
"ordersn"=>'25451548412487',
"proName"=>'电脑',
"name"=>'李四',
"phone"=>"1564845487",
"proNum"=>1,
"proPrice"=>4600
),
);
$returnData = [];
foreach($orders as $k => $v){
if(isset($returnData[$v['ordersn']])){
$returnData[$v['ordersn']]['product'][] = [
'proName' => $v['proName'],
'proNum' => $v['proNum'],
'proPrice' => $v['proPrice']
];
}else{
$returnData[$v['ordersn']] = [
'ordersn' => $v['ordersn'],
'product' => [[
'proName' => $v['proName'],
'proNum' => $v['proNum'],
'proPrice' => $v['proPrice']
]],
'name' => $v['name'],
'phone' => $v['phone']
];
}
}
print_r(array_values($returnData));die;
