ermm ‘ over "
Ok, so I heard that you only use ” when theres a variable involved, because it takes up time… other wise use ‘.. right? well.. what if you have n?.. THe ‘ doesn’t work with n.. so should I use ” or say ‘this text.. + new line ‘ . “n”; hm? This is probably a dumb question, but up until now, I thought I knew php pretty well, but it turns out theres much for me to learn, so thats why I’m asking.. I’m expecting that it wold be easier to use ” because then it doesn’t compute two different things..
hehe thanks..
