I am not sure if I got the terms right in my title, but I am trying to do a php array_push like so
array_push($countryList, "US" => "United States");
but this gives me a syntax error.
Am I not doing this properly?

Adding like
$countryList["US"] = "United States";
Pushing a value into an array automatically creates a numeric key for it.
When adding a key-value pair to an array, you already have the key, you don't need one to be created for you. Pushing a key into an array doesn't make sense. You can only set the value of the specific key in the array.
// no key
array_push($array, $value);
// same as:
$array[] = $value;
// key already known
$array[$key] = $value
;

Try using this array merge method :
$countryList = array_merge($countryList, array("US" => "United States"));

If you want to push a value with key in an array then you may use the following function:
function array_push_assoc($array, $key, $value){
$array[$key] = $value;
return $array;
}
Usage: $array= array_push_assoc($array, 'US', 'United States');

Refer to online php doc ...
"US" => "United States" is not a var !
