PHP中的for循环问题，用于将数组中的相同元素分组为一个

I get some data in an associated array, see image for data,

Here I want to group all elements with party value. Each array may have different party name but arrays with a similar party to be grouped and displayed in the page.

What I tried is, Here I can successfully separate golaRate and rate, but I need specific party name for golaRate and rate

@foreach($data as $bill_data)
        @if(!$bill_data['golaRate'])
            {{-- @foreach($bill_data['party'] as $party) --}} --> this the problem here

@foreach($data as $bill_data)
        @if(!$bill_data['rate'])
            {{-- @foreach($bill_data['party'] as $party) --}}

am using laravel framework.

I am not sure this is your requirement or not, hope this may help

<?php
$array = array(
    array(
        "lotname"=>"456",
        "quantity"=>"456",
        "rate"=>"5",
        "golarate"=>null,
        "userId"=>null,
        "party"=>"fds",
        ),  
    array(
        "lotname"=>"456",
        "quantity"=>"456",
        "rate"=>"5",
        "golarate"=>null,
        "userId"=>null,
        "party"=>"fds",
        ),  
    array(
        "lotname"=>"456",
        "quantity"=>"456",
        "rate"=>"5",
        "golarate"=>null,
        "userId"=>null,
        "party"=>"bbb",
        ),  
    array(
        "lotname"=>"456",
        "quantity"=>"456",
        "rate"=>"5",
        "golarate"=>null,
        "userId"=>null,
        "party"=>"bbb",
        ),
    ); 

function groupParty($data)
{
    $grouped = [];
    foreach ($data as $value) {
        $grouped[$value['party']][] = $value;
    }
    return $grouped;
}

print_r(groupParty($array));
?>
