Exporting Excel Files to Client Downloads Using PHPExcel

When working with PHPExcel to generate Excel files, it is often desirable to provide the option for users to download these files without saving them on the server. Alternatively, you may want to delete the files after the download is complete.

To bypass saving the file on the server and redirect it directly to the client's browser for download, use the php://output stream as the target for saving:

<code class="php">$objWriter->save('php://output');</code>

Additionally, setting proper headers is crucial for file downloads:

<code class="php">// Set the MIME type for an Excel file
header('Content-type: application/vnd.ms-excel');

// Specify the filename for the downloaded Excel file
header('Content-Disposition: attachment; filename="file.xls"');

// Write the Excel file to the browser
$objWriter->save('php://output');</code>
