|In this PHP tutorial we will learn about Comparison Operators.
|-
|0:04
|Comparison Operators can compare 2 values, 2 strings or 2 variables that can contain any of them and will act upon that.
|-
|0:12
|For this I am going to use an IF statement.
|-
|0:19
|Lets start by creating the IF statement structure.
|-
|0:30
|My condition is if 1==1.
|-
|0:33
|echo.
|-
|0:36
|True.
|-
|0:39
|and then else.
|-
|0:43
|echo.
|-
|0:46
|False. Remember I don't need these brackets so I'm going to take them out.
|-
|0:51
|Lets indent it
|-
|0:53
|Never mind the indenting.
|-
|0:58
|This is the first comparison operator.
|-
|1:02
|2 = to means comparison operator. We've seen this in the IF statement before.
|-
|1:06
|1 does equal to 1 so this will echo True. Lets try it.
|-
|1:11
|We got True.
|-
|1:13
|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
|-
|1:36
|IF 1 greater than or equal to 1, echo True otherwise echo False.
|-
|1:43
|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
|-
|2:12
|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
|-
|2:41
|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
|-
|2:58
|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
|-
|3:05
|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
|-
|3:21
|These are the simple Comparison Operators. Play around with them. See what you can do. Thanks for watching.
