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?

Answer: Use the Square Bracket [] Syntax php // Sample array $array = array("a" => "Apple", "b" => "Ball", "c" => "Cat"); // Adding key-value pairs to an array $array["d"] = "Dog"; $array["e"] = "Elephant"; print_r($array); ?>
We can get the array index by using the array_search() function. This function is used to search for the given element.
The array_push() function inserts one or more elements to the end of an array. Tip: You can add one value, or as many as you like. Note: Even if your array has string keys, your added elements will always have numeric keys (See example below).
Using the array_push method: The array_push is another inbuilt function that can be used in PHP to add to arrays. This method can be used to add multiple elements to an array at once.
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
;
