Since these look like Laravel collections converted to arrays, I would suggest using the inbuilt implode()method.
由于这些看起来像转换为数组的 Laravel 集合，我建议使用内置implode()方法。
As per the docs:
根据文档：
$collection = collect([
['account_id' => 1, 'product' => 'Desk'],
['account_id' => 2, 'product' => 'Chair'],
]);
$collection->implode('product', ', ');
// Desk, Chair
Reference: https://laravel.com/docs/master/collections#method-implode
参考：https: //laravel.com/docs/master/collections#method-implode
However, if they're ordinary arrays, and since it's not a single array, you'd have to write a foreach or flatten it with array_column()before running PHP's ordinary implode()function.
但是，如果它们是普通数组，并且由于它不是单个数组，则必须array_column()在运行 PHP 的普通implode()函数之前编写 foreach 或将其展平。

U could try a simple foreach and add a comma value after every iteration.
你可以尝试一个简单的 foreach 并在每次迭代后添加一个逗号值。
$string='';
foreach ($your_array as $value){
$string .= $value.',';
}

Use a foreachloop twice to segregate the array and use substrto remove the last character
使用foreach循环两次来隔离数组并用于substr删除最后一个字符
$string = '';
foreach($your_array as $a)
{
foreach($a as $b=>$c)
{
$string .= $c.',';
}
}
$solution = substr($string,0,-1);
print_r($solution);
