“As you can see it’s very simple. First we have a string
variable that holds a name. Then we have the “if” statement which
says ‘if the variable called name holds a value that is equal to
peter then perform the program lines in the first set of curly
brackets, otherwise perform the commands in the second set of
brackets’“The first question you might ask is why do we have a double ==
sign, good question. This is because in PHP everything in a
decision has to result in either true or false, and since we use =
to give a value to a variable, then = will always be true (trust
me, computers work that way 😉 ) and thus we would not be able to
get a false. There are some cases where you have to use === (3 = in
succession) but for most of the time == will do just fine.”
