How can PHP be used to integrate PDF.js or pdfobject.com for displaying PDF files on websites across different browsers and devices?

To integrate PDF.js or pdfobject.com for displaying PDF files on websites across different browsers and devices using PHP, you can use the following approach: You can use PHP to dynamically generate the necessary HTML and JavaScript code to embed PDF.js or pdfobject.com on your webpage. This allows you to display PDF files seamlessly across various browsers and devices without compatibility issues. 

```php
<?php
$pdffile = "path/to/your/pdf/file.pdf";

echo '<div id="pdfContainer"></div>';
echo '<script src="https://cdnjs.cloudflare.com/ajax/libs/pdf.js/2.8.335/pdf.min.js"></script>';
echo '<script>';
echo 'var pdfjsLib = window["pdfjs-dist/build/pdf"];';
echo 'pdfjsLib.GlobalWorkerOptions.workerSrc = "https://cdnjs.cloudflare.com/ajax/libs/pdf.js/2.8.335/pdf.worker.min.js";';
echo 'var loadingTask = pdfjsLib.getDocument("' . $pdffile . '");';
echo 'loadingTask.promise.then(function(pdf) {';
echo '  pdf.getPage(1).then(function(page) {';
echo '    var scale = 1.5;';
echo '    var viewport = page.getViewport({ scale: scale, });';
echo '    var canvas = document.createElement("canvas");';
echo '    var context = canvas.getContext("2d");';
echo '    canvas.height = viewport.height;';
echo '    canvas.width = viewport.width;';
echo '    document.getElementById("pdfContainer").appendChild(canvas);';
echo '    var renderContext = {';
echo '      canvasContext: context,';
echo '      viewport: viewport,';
echo '    };';
echo '    page.render(renderContext);';
echo '  });';
echo '});';
echo '</script>';
?>
```

Make sure to replace `"path/to/your/pdf/file.pdf"` with the actual path to your PDF file. This code snippet will dynamically load PDF.js, render the PDF file on a canvas element, and display it within the specified container on your webpage.
