My script returns undefined value from my json_encode php
index.php
<?php
$returnThis['user'] = "Robin098";
$returnThis['id'] = "08465";
echo json_encode($returnThis);
?>
sample.html
<head>
<script>
function clickHere(){
$.get("index.php", function(data) {
alert(data.user);
});
}
</script>
</head>
<body>
<input type="button" onclick = "clickHere();" value="ClickHere!"/>
</body>
How can I fix this?

Where does the
$aReturnvariable e from in your PHP script? You go from$returnThisto$aReturnwith no explanation. – Jasper Commented Dec 9, 2011 at 18:09

Reset to default 3Use the jQuery.getJSON method instead of .get, if you want your JSON to be parsed. Also, make sure that the jQuery library is correctly loaded.
function clickHere(){
$.getJSON("index.php", function(data) {
alert(data.user);
});
}
Currently, you're using $.get(url, function(data){...}). In this context, data is a string containing the response from the server:
{"user":"Robin098","id":"80465"}
Using alert(data) inside the function will show this string.
It looks like you're setting up $returnThis, but then returning $aReturn. Don't you want:
$returnThis['user'] = "Robin098";
$returnThis['id'] = "08465";
echo json_encode($returnThis);
