此问题已在此处有答案：
Get count of each unique value in one column of a 2d array（2个答案）
2天前关闭。
我一直在使用一些测试数据，从MariaDB表中进行以下查询，以获取Google Charts中图表的值：
google.load("visualization", "1", {packages:["corechart"]});
google.setOnLoadCallback(drawChart);
function drawChart() {
var data = google.visualization.arrayToDataTable([
['Date', 'Calls'],
<?php
$query = "SELECT count(origin) AS count, start FROM outbound GROUP BY LEFT(start, 10) ORDER BY start";
$exec = mysqli_query($con,$query);
while($row = mysqli_fetch_array($exec)){
// Format Start Date
$start = date('Y/d/m', strtotime($row['start']));
echo "['".$start."',".$row['count']."],";
}现在，我尝试将其更改为通过API调用从远程服务获取实时数据，该API调用将值提供给名为$calls的数组
下面的代码按预期创建日期，但我无法像以前在select查询中那样按日期对呼叫进行分组以获得正确的计数：
foreach ($calls as $call) {
// Format Start date as Y-m-D to group by date instead of exact timestamp
$start = date_format($call->startTime, 'Y-m-d');
$count = count($calls);
echo "['".$start."',".$count."],";
}有谁能给我指个方向吗

你可以使用array_reduce函数作为方法：
试试PHP here
n7taea2i2#
您可以合并三个函数
array_count_values（计算值出现次数）、array_column（仅提取startTime）和array_map（格式化日期）结果：
试试看：https://3v4l.org/bTST2
