Since you are running from the command line, the most you should expect is a text display in the terminal. &nbsp;That will not launch a browser that will show you a web page. &nbsp;And if the PHP command line is not installed or enabled, it may not show you anything but an error.

<div>
PHP command line is installed already. How to run the .php file?
</div>


<div>
This is all I have to do.<br />
<br />
[root@dibscos6 html]# php phpinfo.php
</div>


<div>
I'm running that in the same way like you. Why can't the .php file be displayed on browser?
</div>


<div>
That command runs the PHP program in the terminal and the web browser (Firefox) does not run in the terminal. &nbsp;To run Firefox from the command line to view that page, you would have to start Firefox, not PHP. &nbsp;I'll show you in the next comment.

I get the current problem when issuing<br />
firefox <a href="http://localhost/info5.php" rel="ugc">http://localhost/info5.php</a><br />
<br />
while info5.php does exist within<br />
/var/www/html/

<div>
Can you connect to any other page like index.html?

PHP is a widely-used server-side scripting language especially suited for web development, powering tens of millions of sites from Facebook to personal WordPress blogs. PHP is often paired with the MySQL relational database, but includes support for most other mainstream databases. By utilizing different Server APIs, PHP can work on many different web servers as a server-side scripting language.

Web development includes all aspects of presenting content on intranets and the Internet, including delivery development, protocols, languages and standards, server software, browser clients, databases and multimedia generation.

Web Development

A scripting language is a programming language that supports scripts, programs written for a special run-time environment that automate the execution of tasks that could alternatively be executed one-by-one by a human operator. Scripting languages are often interpreted (rather than compiled). Primitives are usually the elementary tasks or API calls, and the language allows them to be combined into more complex programs. Environments that can be automated through scripting include software applications, web pages within a web browser, the shells of operating systems (OS), embedded systems, as well as numerous games. A scripting language can be viewed as a domain-specific language for a particular environment; in the case of scripting an application, this is also known as an extension language.

Scripting Languages

Kernel programming for Linux operating systems can be done with many different languages; C, C++, Python, Perl and Java, which are some of the most common languages used.There are also many different varieties of Linux, such as Ubuntu, Fedora and OpenSUSE.

Web development can range from developing the simplest static single page of plain text to the most complex web-based internet applications, electronic businesses, and social network services using a wide variety of languages and standards, including the familiar HTML, JavaScript and jQuery, ASP and ASP.NET, PHP, ColdFusion, CSS, PHP, Flex and Flash, but also the implementation of a broad list of standards including XML, WSDL, SSDL, VoiceXML and many more.
