PHP Linux installation or php upgrade howto

Q. How do I install PHP under Red Hat enterprise Linux?


A. PHP (Hypertext Preprocesso) is a server-side web programming language that you can embed into HTML pages. When a user accesses a PHP-based page, PHP dynamically creates a web page that is then passed to the browser.

PHP works with Apache, Lighttpd and other webservers. PHP offers built-in database integration for several commercial and non-commercial database management systems. It also has the ability to perform many useful Web-related tasks using a large set of built-in functions.

PHP generally runs on a web server, taking PHP code as its input and creating Web pages as output, but command-line scripting and client-side GUI applications are part of the three primary uses of PHP as well. PHP can be deployed on any web server and on almost every OS platform free of charge.

Installing PHP is easy these days.

    Is it me or everyone is kind of trying NOT to answer the question? It’s like: I know how to update PHP but I don’t really care to help anyone else because I spent hours googling and some noob wants it on a plate.

    Don’t you just love the Open Source community spirit?

    At the end of the day, yum update php is NOT the solution. Because the problem is upgrading to a version of PHP that you actually want…

    Goodness, I wasn’t trying to garner any awe. I was venting because developing on a closed network RHEL server is a major pain in the ass! No repo’s make me cry hard.

    I forgot I even made this post haha. I’m faced with more of the same and started looking for a PHP upgrade procedure via BASH landed me back here…

    PHP 5.0 on the production server but my dev server is using 5.2 so when I went to stand up a Flex application today the DateTime function bit me.

    By the way, the network is still SECRET and will always be regardless if I speak of it or not.

    /google on MOAR!

    You must have a way to download files, if you can get a .gz source file.

    For example: at home, find the RPM for the package you want to use, burn it to a CD, take it to work, mount the CD, then use the rpm command to install the package.

    If bringing a file from home isn’t permitted, then ask your network admins to get the rpm file for you from the ‘net and copy it to your secret network. Then use rpm to install it.

    I have difficulty to upgrade my Red hat 5.6 Server’s Php version 5.1.6 to 5.5. Can anyone guide me the steps which I should follow.
    I have downloaded .tar file, unzipped then ran the configure and make install commands. Then it shows php 5.5 when I’m running php -v command. But running the script for finding php details in browser its still showing 5.1.6 .
