PHP is a scripting language that runs on a web server, producing output in the form of HTML pages. PHP has many features that simplify collaboration with databases such as MySQL and allow you to build rich web applications such as content management systems.

Since PHP is an open source project, it has become very widespread and is used on many websites. Applications range from simple forms to complex management systems and shops.

Files with the extension PHP5 can contain pure PHP source code as well as this embedded in an HTML. It is similar to ASP, CGI or JSP.

All you need to do to edit a PHP5 file is a text editor. But there are also complete development environments that greatly simplify the development of PHP scripts.

The suffix PHP5 or php in a URL (in the address line of a browser) indicates that PHP is being used on the website. The user of the website receives only the PHP script generated HTML document, not the actual PHP script.

The usual extension for PHP files is php. The version in the extension is not obligatory. However, if used for referencing, it must of course persist. Note, however, that some providers only support PHP up to version 4.

How to open a PHP5 file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the PHP5 file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a PHP5 file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support PHP5 files. At this point we are looking for disk space where the application was installed in and we can link it with a PHP5 file. Since then, our operating system will use the selected program to support all PHP5 files.

Other issues

Despite the described problem with PHP5 there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the PHP5 file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the PHP5 file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
