PHP trying to add a value with a key to an existing array

  • 772

I have this array:

$datos = array(
        'titulo' => $titulo, 
        'contenido' => $contenido, 
        'usuario' => $usuario
    );

And I want to add a new element but not only the value but also a key to be able to identify it, as it is in the array $datos that I have already created.

So I try this:

array_push($datos, 'url_img' =>$fileNameNew);

but basically it tells me that it cannot have a key , but I would be interested in saving it with its key so that I can deal with it later in certain functions

    Where I know there is no function to add arraya new key and value.

    So I've created one:

    function addKeyAndValue( &$array, $key, $value ) {

    $array[$key] = $value;
}
