you need to make the html into a php like this:thanks but i cant echo PHP in a html script
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.0/jquery.min.js" type="text/javascript"></script>
<script language="javascript">
$.ajax({
url: [i]url[/i],
dataType: 'json',
data: [i]data[/i],
success: [i]callback[/i]
});
<?php
$_SESSION['arr'] = $arr
echo $arr;
session_destroy(); //If you want to remove the global variable again
?>
</script>
so if you test this php file you shouldn't see the php but the php results when you check the page source from within the browser.
<input class="input" type="text" name="name" <?php if(preg_match('/(?i)msie [6-9]/',$_SERVER['HTTP_USER_AGENT'])) { echo 'value'; } else { echo 'placeholder'; }?>="Name" />

yes that is it now i have the array how do i get it globalAre you trying to access the array/json returned by test.php inside test.html?
If so, the PHP part is correct, but you need to access the json returned inside the callback:<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.0/jquery.min.js" type="text/javascript"></script> <script language="javascript"> $.ajax({ url: "test.php", dataType: 'json', success: function(json) { // json now holds the array ["foo", "bar", "baz", "blong"] console.log(json); } }); </script>

by global i mean this
works$.getJSON("test.php", function(data){ userCoor = data; document.write(data); });Dont work$.getJSON("test.php", function(data){ userCoor = data; }); document.write(data);
document.write(data);
$.getJSON("test.php",
function(data){
userCoor = data;
// Do something with the data, like pass it off to another function which modifies the DOM.
});
