| 00:00 | In this PHP tutorial we will learn about Comparison Operators. |
| 00:05 | Comparison Operators can compare 2 values, 2 strings or 2 variables that can contain any of them and will act upon that. |
| 00:15 | For this I am going to use an IF statement. |
| 00:19 | Lets start by creating the IF statement structure. |
| 00:25 | My condition is if 1==1. |
| 00:30 | echo. |
| 00:33 | True. |
| 00:37 | and then else. |
| 00:42 | echo. |
| 00:44 | False. Remember I don't need these brackets so I'm going to take them out. |
| 00:51 | Lets indent it |
| 00:56 | Never mind the indenting. |
| 00:59 | This is the first comparison operator. |
| 01:02 | Two = to means comparison operator. We've seen this in the IF statement before. |
| 01:08 | 1 does equal to 1 so this will echo True. Lets try it. |
| 01:13 | We got True. |
| 01:15 | Let me change this. IF 1 is greater than 1 then lets see what result we get. |
| 01:27 | False, because 1 is equal to 1 and not greater than 1. |
| 01:33 | Now lets change this to 1 greater than or equal to 1 |
| 01:37 | IF 1 greater than or equal to 1, echo True else echo False. |
| 01:45 | Here we should get True. |
| 01:48 | You can also do the same with less than or equal to. So for example less than |
| 01:55 | would be False, less than or equal to would be True. |
| 02:01 | We can also say not equal. So if 1 is not equal to 1 echo True |
| 02:11 | Refresh. We'll get False here because 1 is equal to 1. Now lets say if 1 isn't equal to 2 |
| 02:20 | We get True because 1 is not equal to 2 |
| 02:25 | These are the basic Comparison Operators that you will be using for our tutorials |
| 02:33 | Expand on this - practice them - and you'll understand them better |
| 02:40 | You can also compare variables using these operators. So for example num1 = 1 |
| 02:48 | num2 = 2. All we now do is replace these values and there we go |
| 03:01 | 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 |
| 03:11 | 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 |
| 03:24 | These here are the simple Comparison Operators. Play around with them. See what you can do. Thanks for watching. |
