I wonder if you have any way to install PHP 5.4 on Debian 7.5 via
apt-get, adding some URL in
I added the following lines however it asks a lot of dependencies:
deb http://packages.dotdeb.org/ squeeze-php54 all deb-src squeeze-php54 all http://packages.dotdeb.org
apt-cache search php-- as suggested in any Debian handbook?
