What are the potential performance issues or limitations when using PHP to display Powerpoint slides in a browser?

One potential performance issue when using PHP to display Powerpoint slides in a browser is the large file size of Powerpoint files, which can slow down the loading time of the slides. To solve this issue, you can convert the Powerpoint slides to a more web-friendly format like images or PDFs before displaying them in the browser. 

// Convert Powerpoint slides to images using a library like PHPPresentation
require 'vendor/autoload.php';

// Load the Powerpoint file
$objPHPPowerPoint = new PhpOffice\PhpPresentation\PhpPresentation();
$objPHPPowerPoint->getLayout()->setDocumentLayout(PhpOffice\PhpPresentation\DocumentLayout::LAYOUT_SCREEN_16X9);

// Loop through each slide and save as an image
foreach ($objPHPPowerPoint->getSlides() as $slide) {
    $slide->getThumbnail()->setResizeProportional(false);
    $slide->getThumbnail()->setResizeOnOverflow(false);
    $image = $slide->getThumbnail()->getImage()->getBinaryData();
    file_put_contents('slide_' . $slide->getSlideNumber() . '.jpg', $image);
}

// Display the converted images in the browser
foreach (glob("slide_*.jpg") as $image) {
    echo '<img src="' . $image . '" />';
}
