a customer contacted me site being slow , still run on php 5.3 instead of php 7. read somewhere, how faster php 7 , of course wants me upgrade server php 7.

the problem see, website running on old symfony 2.1 installation. far, found out, symfony >= 2.3 run on php 7. know symfony 2.1 php 7 compatibility or has actual hands on knowledge?

if ain't possible, i'll suggest update website symfony 2.3 shouldn't big pain in ass.
