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
;
