how to solve anonymous array? - php

Question

this is my php sql code
//fetch table rows from mysql db
$sql = "select * from tbl_sample";
$result = mysqli_query($connection, $sql) or die("Error in Selecting " . mysqli_error($connection));
//create an array
$emparray = array();
while($row =mysqli_fetch_assoc($result))
{
$emparray[] = $row;
}
$info = json_encode($emparray);
echo $info;
//close the db connection
mysqli_close($connection);
?>
when I run this code i'm getting an an anonymous json array like this.
[{"id":"1","country":"india","domain":"MBA"},{"id":"2","country":"england","domain":"cricket"},{"id":"3","country":"pakistan","domain":"MTECH"},{"id":"4","country":"newzeland","domain":"bba"}]
is there a way to give this array a name because without a named array I don't know how to use this json data for dust.js template. If not suggest me how I can use this data for my templating. thank you.

//fetch table rows from mysql db
$sql = "select * from tbl_sample";
$result = mysqli_query($connection, $sql) or die("Error in Selecting " . mysqli_error($connection));
//create an array
$emparray = array();
while($row =mysqli_fetch_assoc($result))
{
$emparray[] = $row;
}
$mydata['my_data'] = $emparray;
$info = json_encode($mydata);
echo $info;
//close the db connection
mysqli_close($connection);
Try this. Your data will look like this
{"my_data":[{"id":"1","country":"india","domain":"MBA"},{"id":"2","country":"england","domain":"cricket"},{"id":"3","country":"pakistan","domain":"MTECH"},{"id":"4","country":"newzeland","domain":"bba"}]}

When building your array, you need to setup your keys using whichever unique value you want. For example:
while($row =mysqli_fetch_assoc($result)) {
$key = $row['domain'];
$emparray[$key] = $row;
}
This will result in your JSON being keyed with the domain value.
