I am building a simple PHP gallery that dynamically scans folders and displays images. Currently, the script works well for standard image formats like JPG, PNG, and GIF. However, I want to extend this functionality to include PDF files.
The Goal: When the script encounters a PDF file in the directory, I don't want it to just show a broken image link or a text URL. Instead, I want it to display a specific "PDF icon" image that acts as a thumbnail, which users can click to open the document.
The Logic:
Update the glob or extension filtering to recognize .pdf files.
In the foreach loop, check the file extension.
If it's an image, render the file itself.
If it's a PDF, render a local pdf-icon.png.
