how to stick with php5 5.3.x ?

["J. Bakshi" <bakshi12@gmail.com>]

Dear list,

This is a debian wheezy and have php 5.4.x.
I need to stick with php 5.3.x and to achieve this I have added
the following at my sources list

` ` ` `
deb http://ftp.debian.org/debian squeeze main contrib non-free
deb http://security.debian.org squeeze/updates main contrib non-free

` ` ` `

After apt-get update; I get both 5.3 and 5.4 of php5. But every time
it calls the 5.4.x of php5. How can I install the 5.3.x series then ?

Any alternative way is also welcome.

Thanks
