将数组值分配给PHP变量

I have some code which checks to see whether a certain variable is an array. If it is, I would like to assign all the array values to a single, comma-separated PHP variable. Here is the code:

我有一些代码检查某个变量是否是一个数组。如果是，我想将所有数组值分配给一个逗号分隔的PHP变量。这是代码：

if (is_array($value)) {         
    //Need to assign the array variables to the PHP variable $files, but how?
    $postdata.=$files;          
} else {
    $postdata.=$value;
}  

I have tried to use $files = print_r(array_values($value)); but it does not seem to work for me. What am I doing wrong? Thanks.

我试过使用$ files = print_r（array_values（$ value））;但它似乎对我不起作用。我究竟做错了什么？谢谢。

Add this line: $files= implode(',', $value);
