Excel 2 csv using Excel

[sticks]

I am trying to use PHP to create a comma seperated value file from an excel file. I can open the excel file and save it back to the server but I have not been able to change the file format to csv.

This is the code I am using

<?php
echo "Opening Excel...";
// create an object instance
$excel = new COM("Excel.Application") or die("Excel could not be
started");

// pop open the Excel application
$excel->Visible = 0;

// turn off alerts
$excel->DisplayAlerts = 0;

// add a workbook
echo "<br>Open Excel File...";
//echo com_get($excel, FileFormat);

//c:\documents and settings\all users\documents\htdocs\forsale\foreclosure
$excel->Workbooks->open("c:\documents and settings\all users\documents\htdocs\forsale\forclosure\pnwlist.xls");

// save
echo "<br>Saving CSV File...";

/ This is the line that doesn't work /
$excel->Workbooks[1]->SaveAs.FileFormat=="xlCSV"; //, "FileFormat:=xlCSV"

$excel->Workbooks[1]->SaveAs("C:\pnwlist.csv");

// close the application
echo "<br>Quiting Excel...";
$excel->Quit();

echo "<br>Clear Memeory Excel...";
$excel = null;

?>

Shouldn't the == be just = ?

$excel->Workbooks[1]->SaveAs.FileFormat=="xlCSV"; //, "FileFormat:=xlCSV"

I tried that and get the following error message:

Parse error: parse error, unexpected '=' in c:\documents and settings\all users\documents\htdocs\forsale\exceltest.php on line 22

I believe the problem is how I set the value for FileFormat, but I cannot figure out how to set it correctly.

Thanks for your thoughts.
