A certain kind of developer loves to hate on PHP. They are really going to hate where PHP’s custodians are taking it next.
PHP was created by Danish programmer Rasmus Lerdorf in 1995. In 1997, Israeli programmers Andi Gutmans and Zeev Suraski rewrote the parser, creating the base for PHP 3. By 1999, they had built the Zend Engine, which is still the interpreter for PHP.
Gutmans and Suraski continued their partnership with Zend Technologies, a commercial entity that creates add-on products and services for PHP developers, particularly developers in the enterprise.
Today, after multiple massive iterations to the codebase, 35 percent of web traffic is handled by PHP, says Gutmans. Wikipedia says 75 percent of websites use PHP. Facebook, Wikipedia, Yahoo, and Photobucket are all built in PHP. WordPress, the most popular blogging platform in the world, runs on PHP and probably accounts for half of that 35 percent. Most of the other major content management systems, such as Drupal and Joomla, are also built in PHP.
