PHP 8.0 has just been released! This new major version adds several significant features and improvements to the language like attributes, match expressions, Just-In-Time compilation (JIT), and much more!

Here’s a brief guide on how to install PHP 8.0 on Linux, Windows, and Mac OS X:

Ubuntu

Although Composer 2 is mostly backward-compatible with projects using Composer 1, some users may need to continue using Composer 1 due to plugin incompatibilities. This article shows how to install both versions side-by-side.

As you may know, Git is not a single application, but rather a toolkit containing many small programs and scripts that can manipulate the repository. This makes it trivial to chain those components into more-powerful, custom commands which can be defined as git aliases.

Here are some of the more-useful aliases I use on a daily basis:

I recently upgraded my system from Ubuntu 16.04 with Unity to Ubuntu 17.10 with Gnome Shell 3. One of the “features” I found annoying was that my IDE PhpStorm was not popping to the front and receiving focus whenever breakpoints were hit. I eventually figured out a solution and wanted to document it in case others were also searching for a solution.

I first confirmed that “Focus application on breakpoint” was indeed enabled in my settings:

PKCS#12 archives (commonly known as .pfx files) usually contain both a certificate and its private key, sometimes with password protection. In order to use these with a server like nginx or Apache, we need to extract these objects and convert them using openssl.

(The commands below assume your file is named certificate.pfx.)

Extracting the private key

openssl pkcs12 -in certificate.pfx -out private.key -nocerts -nodes

Creating manual backups of a website can be a time-consuming task. Using Linux, you can automate the entire download/transfer using the handy utility known as wget (Ubuntu users: install it with sudo apt-get install wget)

Here’s the command to use for downloading your backup:

wget ftp://yourwebsite.com/some/directory -nv -r -N -l inf -nH --ftp-user='username' --ftp-password='password'
