Since I couldn’t just install the php53 packages as they would conflict with the php packages, I had to remove all the existing PHP packages and install the new ones. This meant that I had to take stock of exactly what packages I had to remove and replace.
I used the yum commands list command to quickly get this information:
[user@server ~]$ yum list installed | grep php | cut -d’ ‘ -f1
php.x86_64
php-cli.x86_64
php-common.x86_64
php-devel.x86_64
php-gd.x86_64
php-mbstring.x86_64
php-mysql.x86_64
php-mcrypt.x86_64
php-pdo.x86_64
php-pear.noarch
php-pgsql.x86_64
php-xml.x86_64
php-xmlrpc.x86_64
[user@server ~]$
The | cut -d’ ‘ -f1 part at the end is just some fanciness to show only the package name and not the extra cruft.
Next I checked to make sure that those packages were available for php53:
[user@server ~]$ yum search php53 | cut -d’ ‘ -f1 | grep php
php53.x86_64
php53-bcmath.x86_64
php53-cli.x86_64
php53-common.x86_64
php53-dba.x86_64
php53-devel.x86_64
php53-gd.x86_64
php53-imap.x86_64
php53-intl.x86_64
php53-ldap.x86_64
php53-mbstring.x86_64
php53-mysql.x86_64
php53-odbc.x86_64
php53-pdo.x86_64
php53-pgsql.x86_64
php53-process.x86_64
php53-pspell.x86_64
php53-snmp.x86_64
php53-soap.x86_64
php53-xml.x86_64
php53-xmlrpc.x86_64
[use@server ~]$
I quickly noticed that neither php53-mcrypt.x86_64 nor php53-pear.noarch were available. I would have to install these manually.
First, I shut down the Apache server as I didn’t want people going to broken pages as I did these updates:
[user@server ~]$ sudo service httpd stop
Stopping httpd: [ OK ]
[user@server ~]$
Next, I remove the old PHP packages:
[user@server ~]$ sudo yum remove php php-cli php-common php-devel php-gd php-mbstring \
php-mysql php-mcrypt php-pdo php-pear php-pgsql php-xml php-xmlrpc

Now it’s time to get the other PHP elements that were not available as packages.
Install PHP mcrypt
The php53-mcrypt package wasn’t available, so we have to install it manually. The following steps will accomplish this.
We first need to install the development package for mcrypt:
[user@server ~]$ sudo yum install php53-devel libmcrypt-devel
PHP’s mcrypt extension can be compiled and installed from the source code, so we need to download and unpackage the PHP 5.3.3 source. You can find a download link on the PHP releases page. I used wget to make the process a bit quicker:
[user@server ~]$ wget http://museum.php.net/php5/php-5.3.3.tar.gz

[user@server ~]$ tar xf php-5.3.3.tar.gz
[user@server ~]$
Now we need to compile and install the mcrypt extension:
[user@server ~]$ cd php-5.3.3/ext/mcrypt/
[user@server mcrypt]$ phpize

[user@server mcrypt]$ sudo make install
Installing shared extensions: /usr/lib64/php/modules/
[user@server mcrypt]$
Now all we have to do is set up the mcrypt.ini file so that the mcrypt extension loads with PHP. This file needs to reside at /etc/php.d/mcrypt.ini.
[user@server mcrypt]$ echo -e “; Enable mcrypt extension module\nextension=mcrypt.so” | \
sudo tee /etc/php.d/mcrypt.ini
; Enable mcrypt extension module
extension=mcrypt.so
[user@server mcrypt]$
Install PHP Pear
Finally, I need to install PHP Pear. If you haven’t used it, it is essentially a code repository tool for easily installing, upgrading, and managing hosted code. It is basically PHP’s version of Perl’s CPAN.
Installing this is fairly straightforward.

PHP Warning: date(): It is not safe to rely on the system’s timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier.

Notice that ugly mess about the date() function. It’s PHP 5.3-specific. I posted how to fix it here.
