I want to create a graph that the data are from oracle by using php. I did not found example that use oracle as a database. Mostly are from mysql. The data is like this
I have made this code but it's not working.
its show like this
data.php
<?php
header('Content-Type: application/json');
$conn = oci_connect('***', '***', '127.0.0.1/orcl');
$graph=sprintf("SELECT count(pm.packagename) as quantity,pm.packagename
FROM packagemenu pm
INNER JOIN orderdetail od ON od.packageid=pm.packageid
inner join orders o on o.orderid = od.orderid
group by pm.packagename");
$parse=oci_parse($conn,$graph);
oci_execute($parse);
$data=array();
while($row1 = oci_fetch_array($parse)){
$data[]=$row1;
}
print json_encode($data);
?>
