write a php script to insert text into an image based on filename

I have a set of jpg images named xyz .jpg and I need to insert a white rectangle into the image and a text "xyz" on top of it. The size of the rectangle is 163x55 pixels, the font of the text is Gotham medium, size of the font is 10px, color of the font is black. position of the rectangle is 1563x620, text in in the center of the rectangle. The UI is simple, just specify path for input files and specify path for output files. output files will be PNG format. I have a similar script so I can provide you with the code. see attached images for clear understanding. the script will run on a localhost server
