PHP - adding an object with its properties to array

Question

I have a problem with modifying an array.

foreach ($page->getResults() as $lineItem) {
  print_r($lineItem->getTargeting()->getGeoTargeting()->getExcludedLocations());
}

This code gives a result:

Array
(
    [0] => Google\AdsApi\Dfp\v201611\Location Object
        (
            [id:protected] => 2250
            [type:protected] => COUNTRY
            [canonicalParentId:protected] =>
            [displayName:protected] => France
        )
)

I'm trying to add another, [1] , same type of object to this array.

I made a class to create and add an object:

class Location{
    public function createProperty($propertyName, $propertyValue){
        $this->{$propertyName} = $propertyValue;
    }
}

$location = new Location();
$location->createProperty('id', '2792');
$location->createProperty('type', 'COUNTRY');
$location->createProperty('canonicalParentId', '');
$location->createProperty('displayName', 'Turkey');    

array_push($lineItem->getTargeting()->getGeoTargeting()->getExcludedLocations(), $location);

Then, if I pass this into print_r() function

print_r($lineItem->getTargeting()->getGeoTargeting()->getExcludedLocations());

It shows the same result.

In the end, I need to send this updated whole $lineItem to this function

$lineItems = $lineItemService->updateLineItems(array($lineItem));

But seems like before sending I can't properly add an object to the array.

Thanks in advance.

Arrays in PHP can have elements of different types. Your code should work even if the objects in the array are different. Look for other problems in your code — Ahmad Essam

The line you're using to both array_push and print_r is a method that is read only and used to get the excluded locations from your object. It would suggest to me that your issue is you're reading from the object, and not saving anything to the object. Try assigning the ...getExcludedLocations() result to a variable, like $excludedLocations. Then array_push to that variable to update it. Then commit that variable back to ...setExcludedLocations() (used to set the locations on the object) to update the object. then you can commit the object back. — Luke

Hi Luke, Thnanks for your reply. I updated as you said $excludedLocations = $lineItem->getTargeting()->getGeoTargeting()->getExcludedLocations(); array_push($excludedLocations, $location); if I print this variable it shows two elements. Could you tell me, how do I need to set it to object to save it? — Geobo

PHP returns arrays as a value instead of as a reference. This means you must set the modified value back somehow.

Looking at the library apparently in question, there seems to be setExcludedLocations method for that purpose.

So your code should be something like:

$geo_targeting = $lineItem->getTargeting()->getGeoTargeting();
$excluded_locations = $geo_targeting->getExcludedLocations();
array_push($excluded_locations, $location);
$geo_targeting->setExcludedLocations($excluded_locations);
