やりたいこと

同じ名前のレコードのデータがあったら、それぞれデータが異なるので復数欲しい

※名前が昇順である前提

<?php
$data = [
    ['name' => '田中',  '国語の点数' => 777],
    ['name' => '渡部',  '国語の点数' => 62],
    ['name' => '品川',  '国語の点数' => 23],
    ['name' => '品川',  '国語の点数' => 4343],
    ['name' => '滝谷',  '国語の点数' => 93],
    ['name' => '川原田','国語の点数' => 55],
    ['name' => '一色',  '国語の点数' => 27],
    ['name' => '一色',  '国語の点数' => 89],
    ['name' => '高橋',  '国語の点数' => 555],
    ['name' => '高橋',  '国語の点数' => 9999],
];



    foreach ($data as $cnt => $row) {
        if($cnt === 0){
            $key = $row['name'];
            $store[] = $row['国語の点数'];
        }
        if($key === $row['name']){
            $key = $row['name'];
            $store[] = $row['国語の点数'];
        }else{
            $result[$key] = implode(',', array_unique($store));
            $key = $row['name'];
            $store = [];
            $store[] = $row['国語の点数'];
        }
    }

    $result[$row['name']] = implode(',', array_unique($store));

var_dump($result);


結果

array(7) {
  ["田中"]=>
  string(3) "777"
  ["渡部"]=>
  string(2) "62"
  ["品川"]=>
  string(7) "23,4343"
  ["滝谷"]=>
  string(2) "93"
  ["川原田"]=>
  string(2) "55"
  ["一色"]=>
  string(5) "27,89"
  ["高橋"]=>
  string(8) "555,9999"
}
