PHP

PHP is a server-side scripting language designed for web development but also used as a general-purpose programming language. Originally created by Rasmus Lerdorf in 1994, the PHP reference implementation is now produced by The PHP Group. PHP originally stood for Personal Home Page, but it now stands for the recursive backronym PHP: Hypertext Preprocessor.

PHP code may be embedded into HTML code, or it can be used in combination with various web template systems, web content management systems and web frameworks. PHP code is usually processed by a PHP interpreter implemented as a module in the web server or as a Common Gateway Interface (CGI) executable. The web server combines the results of the interpreted and executed PHP code, which may be any type of data, including images, with the generated web page. PHP code may also be executed with a command-line interface (CLI) and can be used to implement standalone graphical applications.

The standard PHP interpreter, powered by the Zend Engine, is free software released under the PHP License. PHP has been widely ported and can be deployed on most web servers on almost every operating system and platform, free of charge.

The PHP language evolved without a written formal specification or standard until 2014, leaving the canonical PHP interpreter as a de facto standard. Since 2014 work has gone on to create a formal PHP specification.

During the 2010s there have been increased efforts towards standardisation and code sharing in PHP applications by projects such as PHP-FIG in the form of PSR-initiatives as well as Composer dependency manager and the Packagist repository.

“pre_get_posts” is a WordPress hook that allows you to modify the current query. Just a quick reminder: when you’re visiting any page of a WordPress install, the system creates a query that depends on the url you’re visiting. This is basically what the template hierarchy does.   (more…)

The WordPress search function is much maligned and there are numerous plugins available to add enhancements but they don’t always provide what you want, especially if you are trying to build a secondary search engine that has specific requirements. (more…)

Organizing your content is one of the core features of a content-management system like WordPress. As such, it creates what are called “taxonomies” to help you keep your content easy to find for both your and your visitors. Today we’re focused on why and how you make a custom taxonomy. (more…)

What seems like one of the most complicated bits of functionality in WordPress is adding meta boxes to the post editing screen. This complexity only grows as more and more tutorials are written on the process with weird loops and arrays. Even meta box “frameworks” have been developed. I’ll let you in on a little secret though: it’s not that...
