I have followed the wget method here hoping it was my solution:

Howto install php 5.2.17 on centos 6 x86_64

However I get the following error when trying to install:

# rpm -ivh php-5.2.17-1.x86_64.rpm
error: Failed dependencies:
        libaspell.so.15()(64bit) is needed by php-5.2.17-1.x86_64
        libcrypto.so.6()(64bit) is needed by php-5.2.17-1.x86_64
        libcurl.so.3()(64bit) is needed by php-5.2.17-1.x86_64
        libpspell.so.15()(64bit) is needed by php-5.2.17-1.x86_64
        libssl.so.6()(64bit) is needed by php-5.2.17-1.x86_64
        php-cli = 5.2.17-1 is needed by php-5.2.17-1.x86_64

Would be awesome if someone could help.

UPDATE:

I have now installed an instance of CentOS 5 and am attempting to install php 5.2.17 yet again...anyone know the best way to deal with the following dependencies:

 libaspell.so.15()(64bit) is needed by php-5.2.17-1.x86_64
    libgmp.so.3()(64bit) is needed by php-5.2.17-1.x86_64
    libpspell.so.15()(64bit) is needed by php-5.2.17-1.x86_64
    php-cli = 5.2.17-1 is needed by php-5.2.17-1.x86_64
    php-common = 5.2.17-1 is needed by php-5.2.17-1.x86_64

Wondering what libgmp, libaspell, php-cli and php-common are and where to get the proper versions for php 5.2.17.

Any help is most appreciated.

Thank you!
