Well I dont know if this is what you want...But... What you are trying to find is
a blank element in an array and get rid of this:

Well there are 2 ways that come to mind: one is a bit simpler but I will do both. The first involves you creating a function and the using a builtin function called array_filter(). (http://www.php.net/manual/en/function.array-filter.php)

Ok so we make a function

function noBlanks($var) {

      return( $var != "");

}// end function

ok so now we use the builtin function

// We will say our array with blanks is
// $blankarray

$newarray = array_filter($blankarray,"noBlanks");

this should get rid of all the blanks but I havent tested it 🙁 . The other way to do it would be to do as follows

$i = 0;
while($i < sizeof($blankarray)) {

   if ($blankarray[$i] != "") 
     $newarray[$i] = $blankarray[$i];

       $i++;

}// end while

Either of these I think should work...
Hope that helps.

Partial success!

Thank you to Haji, who helped me construct this...

<?
$newArray=$arrayname;
function exportArray($inarray)
{
foreach( $inarray as $aKey => $aValue)
{
if(!empty($aValue)){
$var_name = $aKey;
$$var_name = $aValue;
echo "<tr><td width=100>".$aValue."</td></tr>\n";
};
};
echo " ";
}

exportArray($newArray);

// the rest of my script VVVV down there

Now, the NEW problem, grrr.

EVEN when i call exportArray(&$newArray); <-- by reference...it does not overwrite the "newArray" which was my hope so that I could export it to a file.

AND it seems inside the above function, i CANNOT write the variable "$aValue" to a file. I can echo it till the cows come home, LOL, but I cannot write it to a file?....what's up with that?

this is what I tried...

function exportArray($inarray)
{
@ $fp2 = fopen("$DOCUMENT_ROOT/fruitarray.txt", "a");
flock($fp2, 2);
if (!$fp2){
echo " The fruit array could not be processed at this time. "
."Please try again later.</body>";
exit;
}

foreach( $inarray as $aKey => $aValue) 
{ 
	if(!empty($aValue)){ 
		$var_name = $aKey; 
		$$var_name = $aValue; 
		echo "<tr><td width=100>".$aValue."</td></tr>\n"; // everything works up to here
		$teamString = "$aValue";  			// also tried $aValue bare w/ no quotes also...didn't work!
		fwrite($fp2, $teamString);			// tried $teamString bare and in quotes also
		fwrite($fp2, "goo\n");				// breakpoint DOES NOT WRITE... conclusion: cannot write to file INSIDE a funtion.  What's up with that????
		}; 
}; 
flock($fp2, 3); 
fclose($fp2);
echo "<br>";

}

Please help if you can....getting VERY frustrated!!!
