Passing array to PHP

bigpondtinyfish · 06-12-2012, 06:30 PM

Hi, I want to use ajax to pass an array from the javascript in my web page to PHP so that the php can then use it, I want to do this without reloading the page and the array could be quite large so I think i need to use POST. I have been doing one searches and have only seen GET used. Can someone give me a very simple example of how you would pass an array using ajax-POST to PHP? Thanks

Code:

<!doctype html>
<head>
</head>
<body>
 
<script> 
myArray=[];
myArray[0]="zero";
myArray[1]="one";
req=new XMLHttpRequest;
req.open("post","arrayto.php",true)
req.onreadystatechange=function(){
  if (req.readyState==4){
    alert(req.responseText)
    }
  }
params='myArray='+myArray;
req.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
req.setRequestHeader("Content-length", params.length);
req.setRequestHeader("Connection", "close");
req.send(params);
 
</script>
</body>
</html>

on the server ...
$myArray=explode(",",$_POST["myArray"]);
echo "Got it";
