Really what do you need an internal function for something simple like

It may be simple, but it's 60 characters I have to type over and over,
or a user defined function I have to include() from a library file (and
I have to ensure that library file is up to date on 30+ web
applications).
My view of internal functions is that they solve common, repetitive
problems. Sure, some of those problems are quite complex, but others
are not. A perfect example would be array_walk() -- it can be solved
in a one liner too:
foreach ($in as $k = $v ) { $in[$k] = myFunction($v); }
... but someone decided it was useful as an internal function. My hope
was that there was such a function to delete empty array elements
already defined in PHP, but since it appears there isn't, I'll just
keep including my own from a library file.

How about array_filter()? From the docs: If the callback function is
not supplied, array_filter() will remove all the entries of input
that are equal to FALSE.
$a = array ('a' = 'foo', 'b' = '', 'c' = null, 'd' = 99, 'e' = 0);
print_r (array_filter ($a));
// Output:
Array
(
[a] = foo
[d] = 99
)
As a previous poster noted, though, this will only work for you if 0
and the empty string et al. are not significant in your application.

The problem with your function you want is that it is very
specific, the name would have to be something like:
unset_array_items_only_if_val_is_empty($array);

First, let me assure you that this is not one of those shady pyramid schemes
you've been hearing about. No, sir. Our model is the trapezoid!

What about:
array_unset_empty_values() or array_remove_empty_values()
:-)
