Learning php part 1

[[]] is a selfnotation of php coding

[[$Name = ''The variable under the [name]'' ]] for example ''Bob''
This one will be in the form of a string variable meaning it can't be combined with numbers or actual value.
You can combine strings using:[ ''String part, '' . $name; ] and that will result in:[ String part, Bob] .

[+] Means add on numbers
[-] Means minus number
[/] Divide
[*] Multiply
example: $A == $B     means variable A has the same value as variable B.
This will be a question to see if the value is true or fals. If the value for instance A = 3 + 5 and B = 3 then it's fals.
while A = 5 + 3 while B = 8 then it did be true.
Checking if it's not equal would be with[$A !== $B]
Logical rythems like [ $A and $B ] if both are true
[ $A or $b] if one of them is true or both.

The ''if true'' system:
[  $LoggedIn = true;
if ($LoggedIn == true) {
Echo ''You are logged in'';
} else {
   echo '' Please log in''
}								]
Now in this example it would suggest you are logged in because $LoggedIn is set to true. So the result is ''You are Logged in''
if we did change that to false it did look like this:
[ $LoggedIn = false;
if ($LoggedIn == true) { 		] etc. so this one would result into ''Please Log in''
