Working with arrays

[kf4pfw]

Hi:

I have a form with 4 arrays in it. Each array can contain up to 11
elements.

I am using the following code (this is for proof of concept):

<?

if($submit) {

foreach ($_POST['doc'] as $doc1) {
}
foreach ($_POST['doctype'] as $doctype1) {
}
foreach ($_POST['nomen'] as $nomen1) {
}
foreach ($_POST['cage'] as $cage1) {
}
$docstr=implode (",",$doc);
$doctypestr=imp lode(",",$docty pe);
$nomenstr=implo de(",",$nomen) ;
$cagestr=implod e(",",$cage);

print_r(array_u nique($doc));
echo "<BR>Number of elements in DOC: ".count($doc)." <BR>";
print_r($doctyp e);
echo "<BR>Number of elements in DOCTYPE: ".count($doctyp e)."<BR>";
print_r($nomen) ;
echo "<BR>Number of elements in NOMEN: ".count($nomen) ."<BR>";
print_r($cage);
echo "<BR>Number of elements in CAGE: ".count($cage). "<BR>";

}
else
{
?>

<INPUT TYPE=submit NAME=submit VALUE=Submit>

</form>

<?
}
?>

My question is how can I NOT have blank elements counted/displayed?
