在javascript中将数组转换为字符串并在php中返回到数组？

I have an array in javascript, when click a button, I need to print the array as html input value. I did this and it works:

myString = JSON.stringify(results);

After I got the string in php, json_decode($results,true) got null return; How to get the string back to array in php? Or, should I use other ways to convert array to string in javascript at the first place?

update:

This solution works:

$results= preg_replace('/\\\"/',"\"", $results);
$results = json_decode( $results,true );

How ever, I hope there's a better way.

Looks like you have magic quotes on. Disable it to stop the massive multitude of backslashes.
