我已经通过ajax jQuery代码传递了json字符串，然后将其转换为多维关联数组。现在，我在打印此多维关联数组时遇到问题。
// Retrieve the string, which was sent via the POST parameter "user"
$user = $_POST['user'];
// Decode the JSON string and convert it into a PHP associative array.
$decoded = json_decode($user,true,10);
// var_dump the array so that we can view it's structure.
var_dump($decoded);
var userStr = JSON.stringify(connections);
$.ajax({
url: base_url+"ajax/add_google_user",
type: 'post',
data: {user: userStr},
success: function(response){
appendPre(response);
}
});
我正在通过var_dump（$ decoded）进行打印； 我需要用回声打印怎么办？

由于需要打印多维数组，因此可以使用for之类的任意迭代语句，使用echo挖掘和打印数组的所有级别。

如果将true作为第二个参数传递，则可以使用var_export，可以将内容放入变量。
$a = var_export([ 1 => 2 ], true);
echo $a;
如果出于某些晦涩的原因要使用var_dumps，则可以使用缓冲区来捕获输出：
ob_start();
var_dump([ "a" => "1" ]);
$a = ob_get_contents();
ob_end_clean();
echo $a;
