A simple PHP script that automatically downloads and unzips the latest version of Wordpress in the current directory (./), so that I don't have to download it and upload it to my server through FTP manually.
<?php
echo '<pre>';
echo '<span style="color:blue">DOWNLOADING...</span>'.PHP_EOL;
// Download file
file_put_contents('wp.zip', file_get_contents('https://wordpress.org/latest.zip'));
$zip = new ZipArchive();
$res = $zip->open('wp.zip');
if ($res === TRUE) {

CI with Travis, github Releases API, gh-pages and npm publish

CI with Travis, GitHub Releases API and gh-pages

When hosting a project on GitHub, it's likely you'll want to use GitHub Pages to host a public web site with examples, instructions, etc. If you're not using a continuous integration service like Travis, keeping your gh-pages site up to date requires continuous wrangling.

The steps below outline how to use Travis CI with GitHub Releases and GitHub Pages to create a "1-button" deployment workflow. After testing and running a release build, Travis will upload your release assets to GitHub. It will also push a new version of your public facing site to GitHub Pages.

Organize your project

Let's assume you are hosting a JavaScript project that will offer a single JavaScript file as a release asset. It's likely you'll organize your files like this.
