Publisher review:PHP for "PHP: Hypertext Preprocessor", is an extremely popular programming language, primarily on the Internet. The PHP language can be incorporated into the source code of an HTML page, but scripts programmed in PHP focus mainly on the server side. So you can do everything that a CGI program is able to do, such as collecting forms, generating dynamic pages or send and receive cookies, for example. The language differs from Perl and C, since instead of coding a program with many commands to generate an HTML page, you can edit an HTML script containing the necessary code.
What also distinguishes PHP from a client oriented language like JavaScript is that the code is executed on the server. The language is relatively simple to understand making it accessible to beginners, but has many advanced features for professional programmers. Finally, one of the strengths of PHP is its open-source license, which can significantly reduce the cost of developing an infrastructure for a website, for example.
This "release candidate", in addition to the correction of hundreds of bugs in previous versions, includes new features such as namespaces (namespaces), the "anonymous functions" or "lambda functions", the Late Static Bindings (LSB), the MySQL native driver for PHP mysqlnd, a "garbage collector" as well as improvements in the Standard PHP Library.
Operating system:Mac OS X
