Time	Narration
0:00	In this PHP tutorial we will learn about Comparison Operators.
0:05	Comparison Operators can compare 2 values, 2 strings or 2 variables that can contain any of them and will act upon that.
0:15	For this I am going to use an IF statement.
0:19	Lets start by creating the IF statement structure.
0:25	My condition is if 1==1.
0:30	echo.
0:33	True.
0:37	and then else.
0:42	echo.
0:44	False. Remember I don't need these brackets so I'm going to take them out.
0:51	Lets indent it
0:56	Never mind the indenting.
0:59	This is the first comparison operator.
1:02	Two = to means comparison operator. We've seen this in the IF statement before.
1:08	1 does equal to 1 so this will echo True. Lets try it.
1:13	We got True.
1:15	Let me change this. IF 1 is greater than 1 then lets see what result we get.
1:27	False, because 1 is equal to 1 and not greater than 1.
1:33	Now lets change this to 1 greater than or equal to 1
1:37	IF 1 greater than or equal to 1, echo True else echo False.
1:45	Here we should get True.
1:48	You can also do the same with less than or equal to. So for example less than
1:55	would be False, less than or equal to would be True.
2:01	We can also say not equal. So if 1 is not equal to 1 echo True
2:11	Refresh. We'll get False here because 1 is equal to 1. Now lets say if 1 isn't equal to 2
2:20	We get True because 1 is not equal to 2
2:25	These are the basic Comparison Operators that you will be using for our tutorials
2:33	Expand on this - practice them - and you'll understand them better
2:40	You can also compare variables using these operators. So for example num1 = 1
2:48	num2 = 2. All we now do is replace these values and there we go
3:01	This will produce exactly the same result as we've got earlier - which is True. Now all we need to do is change these values
3:11	Please note this will now read as num1 = 1 num2 = 1 so if num1 doesn't equal 1 it is False because 1 does equal 1 therefore we get False
3:24	These here are the simple Comparison Operators. Play around with them. See what you can do. Thanks for watching.
3:33	This is Mad Madhur dubbing for the Spoken Tutorial Project.
