Question

In a constructor of a object, I would like to be able to pass an int variable (representing a id to then fetch to database) or an array (when i already fetched to database)

I tried something like this:

__construct($var){
     if(isset($var['id'])){ /*tried also if($var['id']) != '')*/
        $this->id = $var['id'];
     }else{
        $this->id = $var;
      }
}

The thing is that by passing a int value parameter as $var, it will enter to the first case on the if.

So how can i propper check that $var is an (asociative) array ?

Answer 1

You can use is_int ($var) to check if it is an int and is_array ($var) if it is an array
