This is the code I always used with PHP prior to 4.2.X and 4.3.0:
function ExcelSheet($filein,$tmpdir) {

   $fileout = substr(tempnam($tmpdir, "tmp"), 0, -4);
   $ex = new COM("Excel.sheet") or Die ("Cannot find excel!");
   $ex->Application->Visible = 0;
   $wkb = $ex->Application->Workbooks->Open($filein) or Die ("Cannot open excel!");
   $ex->Application->ActiveWorkbook->SaveAs($fileout, -4143);
   $ex->application->ActiveWorkbook->Close("False");    
   unset($ex);
   return($fileout . ".xls");
}

The excel function works, but afterwards the excel process remains in memory, as other people have already argued.

I see this behaviour on 4.2.3 but not with 4.3.0 on Win2Kpro SP3 Apache 1.3.27 (PHP running as module).
On 4.2.3 the same Excel.exe is reused each time I run a
script very similar to this one. I end up with one Excel.exe left in taskmanager after running this script "1 to n" times.
In 4.3.0 Excel.exe appears for a moment while the script runs then disappears.

I get exactly the same behaviour on Win2k server SP2.

I solved the problem changing the default printer on the server! It seems strange (and it is not) but if I change the printer and put a simple (native and not plugged to the server...) printer as the default printer, rather than a hand-installed one, EXCEL seems to act in the right way. (the printer in question is a Canon Laser SHOT LBP-1210)
EXCEL does not show any strange behavior if it run normally by opening it via the menu. But if it is run via PHP and COM the thing happens
