Stripping out empty elements from arrays

[trooper]

Hi All

I have 3 arrays (1,2,3)

Now i perform some sql query to generate populate each array.

Then later on i merge them together to create a single large array. The problem is that if any of the sql queries results in one of the arrays being empty then that will be in the final array.

Unfortunately i need to merge all 3 arrays together.

I'm then emailing the people in this final array. Obviuosly if the array contains empty values then it'll bounce back to the mailer daemon.

How do i get it so that the final array will only contain values from the arrays that actually have data in them?

Thanks

$new_array = array();
foreach ($old_array as $value)
{
if ($value != '')
$new_array[] = $value;
}

$new_array will contain all values from $old_array except those that are blank.

Thanks a lot

i ended up putting

foreach($sorted_emails AS $user_email)
if($user_email)
{
send email etc
}
}

Note: that may work for strings, but you'll get serious trouble if your array contained numbers?
why? because:

if (0) is false.
So the number zero would never cause a hit, even if you wanted it to.
