If function in php

Question

Help me to understand abuot *if* in php

Answer 1

It's like this :
if(condition){
#do it
}
In condition you can check any thing! If condition was true #do it code will run. but if condition was false #do it code will not run!

In this case if we write :
if(4 == 5)
It's not true so your #do it code will not run.
