Pass json object from php to javascript

Question

I have a json array in php and I want to pass it to javascript so I can use it with google charts.

If I do this:

var a = <?php echo((json_encode($data))); ?>;

I get the data in the format Name,Value,PHP,78,JAVA,1000,HTML,129 but I want to keep it in the json format that it was in

[["Name","Value"],["PHP",78],["JAVA",1000],["HTML",129]]​

because google charts needs to receive it like this. Any idea how to do this?

• Andrei P.: You can't. Only workaround would be using AJAX or something.

<?php
$book = array(
 "title" => "JavaScript: The Definitive Guide",
 "author" => "David Flanagan",
 "edition" => 6
);
?>
<script type="text/javascript">
var book = <?php echo json_encode($book, JSON_PRETTY_PRINT) ?>;
/* var book = {
 "title": "JavaScript: The Definitive Guide",
 "author": "David Flanagan",
 "edition": 6
}; */
alert(book.title);
</script>

try it hope this will help...

• Vickie: no error just still getting it in the wrong format when I test. I think because I am changing it to a javascript variable but I just want to keep it as a json array
• Vickie: <?php $data = Array (); $data [] = Array ("Name", "Value"); $data [] = Array ("PHP", 78); $data [] = Array ("JAVA", 1000); $data [] = Array ("HTML", 129); $table = json_encode($data); echo $table ; ?>
• Vickie: sorry about how it looks, new to stackoverflow, don't really know how to use it
