Track previous link of a site in PHP

I just spotted through Google that Raj Shekhar has quoted my post to comp.lang.php in his Blog Ideas page:

Add this line in the beginning of every script or possibly using a
global-common include file say config.php

Converting PSD with PHP/ImageMagick

After seeing feature rich options in Imagick PECL extension at Mikko Koppanen 's (the author) website and also impressed with ImageMagick 's features, I have decided to use it for the PSD to XHTML conversion website that I'm architecting and managing. Since, the team wants programming help for converting PSD images, I have tried it (documentation is sparse on PSD handling) Converting PSD to PNG/JPEG/etc Note that, flattenImages() is needed for layered/multi-page PSD file. <?php $im = new Imagick('test.psd'); $im->flattenImages(); $im->setImageFormat('png'); $im->writeImage('test.png'); ?> Extracting PSD layers One by one <?php $im = new Imagick('test.psd'); $im->setImageFormat('png'); for ($i = 0, $num_layers = $im->getNumberImages(); $i $im->setImageIndex($i); $im->writeImage('layer' . $i .

Even the Ports-related options are missing from the Command Palette. Solution After a lot of trial and error, here's what worked: Run npx serve in the VS Code terminal. It will output a URL such as http://localhost:3000/ . Click the link (or use the Follow Link option). This will open the app in your default browser. You may notice that it opens on a different port (for example, http://localhost:64198 ). At this point, the Ports tab becomes available in VS Code. After this initial trigger, the Ports tab seems to remain available in future VS Code...
