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.

Can you please provide the detailed step by step process for Upgrading the PHP4 to PHP 5.?
Also the system requirements for this like Zend Engine, Apache server version required or MySQL version required ?
Just run up2dat/yum or apt-get command to update version. If you need more help join our forum
Hello there,
Actually when I run ‘yum update php’ on CentOS 5, it does not update the php to the latest version of 5.2.3 and remains to version 5.1.6 only and says that it can not find any updates.
Anything am I missing?
Regards,
Naresh Khokhaneshiya
Naresh,
5.1.6 is latest and stable for RHEL / CentOS. PHP 5.2.3 won’t be available for CentOS 5.0. You have to wait or compile from source code.
I to in a way have the same problem as Naresh
however a little defferant. I have version 5.1.6
and am trying to install ffmpeg.php it needs the comand phpize to be ran and there is no sush program on my server !
which phpize / it says none
Why would this not get installed with my version of php (any ideas ?) Also if you have any thoughts as to how I can install this please let me no. I realy do not want to have to reinstall php or upgrade.
have you hurd of a patch for this or something?
Thanks Mars
Mars,
Install php-devel package to get phpize binary:
yum install php-devel
Hi,
Thanks for your guide. I ran the update command using yum and my PHP was updating to a version of Nov 2005. My system is Redhat. Can you tell me how to upgrade to the latest PHP version? Do I have to first uninstall the old version or something?
Thanks
John,
If you are using RHEL 4, there is no offical PHP 5 exists. Redhat only provides updates for RHEL 4. I strongly recommend to update your box to RHEL 5.x
HEllo all
I ran this and it installed the phpize
Install php-devel package to get phpize binary:
yum install php-devel
However now when i try to use phpize it says?
make sure you run ‘usr/bin/phpize’ in the top level source directory of the module
I have looked everywhere on the net and there is no help on this that i could find. Do you have any thoughts on what this means?
Thank You
I tryed the command on Ubuntu:
sudo apt-get install php5-cgi php5-cli
Ant it installed the version 5.2.3 of php but the last version is 5.2.6.
It’s not so important, but how upgrade to the last version using apt-get ?
Thanks for this post
Hey, I have the same questions. How is it easier to get the latest version installed, and not the patches. I ran configure make and make install, and I still get the previous version.
It would be great if apt-get would install php 5.2.6
I am on Fedora Core 6 and currently on PHP 5.1.6. When I ran “yum update php” it didn’t pick up the new 5.2 version, any ideas?

fail to update..anyone can help?
What if you want to update PHP that isn’t supported by the vendor? You would need to either build yourself from source or find a pre-packaged PHP. I’ve encountered this with new bleeding edge applications that want the newest PHP 5.2 or 5.3. How do you integrate those versions of PHP with a currently existing Apache?
To update php-4 to php-5 edit your repositories located in (/etc/yum.repos.d), then open CentOS-Base.repo using your favourite editor find [centosplus] below it you will find enable=0 change it to enable=1 an then run yum update php if have any issue do let me know.
