The PHP language has been around for over 20 years and is clearly one of the most popular programming languages in the world. PHP is definitely the lingua-franca for server-side Web programming.
While there is extensive user documentation, the PHP language has always been missing a language specification. That is not to say a specification hasn’t been thought about or discussed. It is just that one has never really come to fruition.
The Chinese philosopher Lao Tzu stated, “A journey of 1,000 miles begins with a single step.” We are excited to announce the initial draft of a specification for PHP.
