Without actually running it (I'm too lazy!), I'm pretty sure this won't work
correctly -- the count($array) is being recalculated each time round the

Not too much
crap - hit 'reply' by mistake.

that only works for numerical indices.
However, if you're sure that neither null values, nor false values are
supposed to be present in the array, (that means, they MIGHT be, but
should be removed anyway; or just not be there at all,) then you could
try array_filter with no callback-argument :)
use the unset() function.
for ($i = 0; $i < count($array); $i++) {
if (empty($array[$i]) {
unset($array[$i]);
}
}

Try it that way first. If not,

eg, this:
what does the value have to do with it??? other than that you want to
remove items where the value is 'empty'.
also 'no value' is vague, do you mean an empty string or do you mean NULL?

Try it that way first. If not,
$name = array_merge($name);
But I think I remember the first way working for me.
