Those on OSX using PHP via Homebrew may be wondering how they can upgrade their systems to the latest version of the language, PHP 7.2. Fortunately, as Freek Van der Herten shows in this new post the upgrade process is just a few quick commands away.

PHP 7.2 was released almost two months ago. I decided to wait a bit until a stable version of Xdebug with PHP 7.2 compatibility was available. And that happened yesterday with the release of Xdebug 2.6.

To make the switch over to PHP 7.2 from 7.1 (or really any other PHP version) it's a simple matter of unlinking the current version and installing PHP 7.2 with the matching Xdebug package. He also includes the commands for installing the packages for Imagick and Redis handling.

The Total PHP site has another introductory tutorial posted showing you how to correctly delete files in your PHP scripts.

Following our tutorials on uploading files and listing files, this tutorial will walk you through deleting files from a directory. This is done using the unlink() function.

Their example is pretty simple (as is the concept) - they show how to check to be sure that the file you want to remove isn't in use/open and then issue the unlink to remove it from the file system.
