Question

这是我的数组

Array
(
[0] => Array
    (
        [0] => SC1MTTCS6J1WK
    )

[1] => Array
    (
        [0] => SC1MTTCSHJ1WK
    )
)

但是当我尝试使用

进行内爆时

$in_text = implode(",", $myArray3);

我无法获得价值，而是得到了这个：

Array,Array

请帮忙谢谢。

Answer 1

这是简单的代码，试试这个

services.AddMvc()
                .AddJsonOptions(opt => {
                    opt.SerializerSettings.ContractResolver = new DefaultContractResolver();
                })

Answer 2

试试这段代码，

$in_text = '';
foreach ($myArray3 as $key=>$val){
    if(is_array($val)) {
        $in_text .= ($in_text != '' ? ',' : ''). implode(",", $val);;
    } else {
        $in_text .= ($in_text != '' ? ',' : ''). $val;
    }
}
echo $in_text;

PS ：这将达到二维数组。

Answer 3

或者，如果您想获得幻想，请在爆炸前使用RecursiveIteratorIterator和RecursiveArrayIterator展平数组。

<?php
$array = [
    ['SC1MTTCS6J1WK'],
    ['SC1MTTCSHJ1WK']
];

$it = new RecursiveIteratorIterator(new RecursiveArrayIterator($array));
$flat = [];
foreach ($it as $value) {
    $flat[] = $value;
}

echo implode(', ', $flat); //SC1MTTCS6J1WK, SC1MTTCSHJ1WK

Answer 4

您在数组数组上调用implode，结果为Array, Array。你可以这样打电话，

implode(",", array_column($myArray3, 0));

内爆后无法返回值
