I have problem with array in PHP.
I've got that code in my Ajax handler PHP page:
if(isset($_GET['dataa']))
{
$dataa = $_GET['dataa'];
$dataa = preg_replace('/\\\"(.*?)\\\"/', '"$1"', $dataa);
$dataa = json_decode($dataa);
echo $dataa[0];
echo $dataa[1];
}
I tried to send data array in JavaScript to the Ajax handler but it's not working so I want to to pass param in the URL.
When I try to put this URL:
...AjaxHandler.php?dataa=["test1","test2"]
I get this: test1test2 and that's ok.
But I don't really understand why I need to use preg_replace and json_decode.
I tried to delete the preg_replace but then it didn't show me anything.
I tried to delete the json_decode too but then I get only [/ on the screen.
I need to send multiple data so I do that with array.
Why I have to use preg_replace?
Is it common to use preg_replace like that? All time when I send data array?
