[RESOLVED] Strip empty values from array

anthill

I did actually find a solution to this at the link below:

http://phpbuilder.com/board/showthread.php?t=10249848&highlight=strip+array+empty+values

yet i can't seem to get it to work with the array i have. Using var_dump($array) i get the following:


array(4)  {
                   [0]=> array(2)
                                      {
                                      [0]=> 1 [1]=> "dog"
                                      }
                   [1]=> bool(false)
                   [2]=> bool(false)
                   [3]=> array(2)
                                      {
                                      [0]=> 2 [1]=> "cat"
                                      }
               }

Now i want to strip out $array[1] and $array[2] as they are giving me bool(false). I don't know much about bool(false) as using isset for the values in the array is returning as true! Does anyone know how i can strip out these two "empty" (bool(false)) values??

Any help is much appreciated!

You need to read more on [man]isset/man and [man]empty/man to decide which you actually want to use.

Thanks for your help.

It's bool(false) i'm not understanding. Is bool(false) a value that's false, empty or 0?? Would isset() or empty() actually pick these up if the value is 0?

As it turns out it is empty() i need.

Cheers again!

bool(false)

It's a boolean that has a value of false.

You might want to look at [man]array_filter[/man].
