Question

I’m trying to build a page which queries my database and then formats output so another webservice/page can access the data.

Ideally I wanted to explore having the data in JSON format, but that is not working. The other problem I have which is more major than the JSON not working is, if I have 3 records in $reportsResult, only the last one is displayed.

Anyone with some help please. Oh do I also need to print_r for the external webpage to retrieve the data or is there a better way?

class Pupil {
    public $FirstName = "";
    public $LastName  = "";
}

foreach($reportsResult->getRecords() as $reportRecord) {
    $Pupil = new Pupil();
    $Pupil->FirstName = $reportRecord->getField('FName');
    $Pupil->LastName = $reportRecord->getField('SName');
}
json_encode($Pupil);

OK managed to figure out how how to get all records from the loop, but its still not displaying in json format when I do a print_r – am I missing something?

$AllPupils = array();

foreach($reportsResult->getRecords() as $reportRecord)
{

$Pupil = new Pupil();
$Pupil->FamID = $reportRecord->getField('FName');
$Pupil->ChildName = $reportRecord->getField('SName');

array_push($AllPupils, $Pupil);
}

json_encode($AllPupils);

You will probably run into issues since json_encode wont handle the whole object. for that, you may want to serialize the $Pupil object.

Something like below may work for you though. It will assign the values to a returned array, which will allow json_encode to execute gracefully:

class Pupil {
    public $FirstName = "";
    public $LastName  = "";

    public function getAttr(){
        return array("FirstName" => $this->FirstName, "LastName" => $this->LastName);
    }
}

$json = array();

foreach($reportsResult->getRecords() as $reportRecord) {
    $Pupil = new Pupil();
    $Pupil->FirstName = $reportRecord->getField('FName');
    $Pupil->LastName = $reportRecord->getField('SName');

    $json[] = $Pupil->getAttr();
}

echo json_encode($json);
