How do I import PHP array in a JSON array? - php

Question

So I have a PHP script where I ask a simple query and then I put it in an array.
<?php
$query = mysql_query('SELECT ATX12V FROM results');
$resultSet = array();
while($row = mysql_fetch_array($query)){
$resultSet['ATX12V'] = $row['ATX12V'];
$data[] = $resultSet;
}
print json_encode($data);
?>
The outcome of print json_encode($data) is:
[{"ATX12V":"10"},{"ATX12V":"65"},{"ATX12V":"64"},{"ATX12V":"96"}]
Below I have a javascript code and my question is how do I add $data to the data[]??
<script>
var buyerData = {
labels : ["January","February","March","April","May","June", "July", "August"],
datasets : [
{
fillColor : "#9DB86D",
strokeColor : "#ACC26D",
pointColor : "#9DB86D",
pointStrokeColor : "#9DB86D",
data : []
}
]
}
</script>

Answer 1

What about simple:
data : <?php echo json_encode($data); ?>

Answer 2

you can use ajax like :
(home.html):
<script type="text/javascript">
window.onload = function() {
$.ajax({
type: "POST",
url: "request.php",
dataType: "json",
success: function (data) {
alert(data[0].ATX12V);
}
});
}
</script>
<script type="text/javascript" src="js/jquery.js"></script>
and server side (request.php) :
<?php
$query = mysql_query('SELECT ATX12V FROM results');
$resultSet = array();
while($row = mysql_fetch_array($query)){
$resultSet['ATX12V'] = $row['ATX12V'];
$data[] = $resultSet;
}
print json_encode($data);
?>
note: Add jquery.js in your project
