Question

I have the following array:

$my_array = array ( 
                 'city'     => $this->input->post('city'),
                 'country'  => $this->input->post('country'),
                 'state'    => $this->input->post('state'),
                 'miles'    => $this->input->post('miles')
                 );

Which short php function or method can I use to check if all array items are set? Right now I’m using the following code

$my_array = array_filter($my_array);

if (!empty($my_array['city']) && !empty($my_array[['miles']) && !empty($my_array[['state']) && !empty($my_array['country']))
{
     //do something
}

note: I’m using the array_filter() function to remove all entries from a query that equal FALSE.

Answer 1

It seems like you can just count the number of elements left after filtering:

if(count($my_array) == 4){
    // all 4 still set
}
