PHP can use the json_encode function and the json_decode function to convert the js array into a php string array

The code example is as follows:

```php
// js 数组
$js_array = array('apple', 'banana', 'orange');
// 使用 json_encode 函数将 js 数组转化为 PHP 字符串
$php_string = json_encode($js_array);
// 输出转化结果（输出：["apple","banana","orange"]）
echo $php_string;
// 将字符串转化为 PHP 数组
$php_array = json_decode($php_string);
// 输出转化结果（输出：Array ( [0] => apple [1] => banana [2] => orange ) ）
print_r($php_array);
```

In the above code , the `json_encode` function converts a JS array into a JSON format string. JSON format strings are often well suited for data transfer or cross-language data exchange. Then, use the `json_decode` function to convert the JSON format string back into a PHP array.

Finally, you can use functions such as print_r or var_dump to print the converted PHP array.
