Hi, I found this article https://www.devops.zone/tricks/install-php-5-6-on-debian-wheezy/ to replace php 5.4 by php 5.6 I use ispconfig 3 and i don't no if it is a good idea. What is your opition ? Best regards
Check backports before you mix in other sources. I would. Isconfig supports php5.6 in Jessie, should work but dont trust me.
Backports and Dotdeb shozld both work. But I would update to Jesse if possible instead of adding php 5.6 to Wheezy.
