|Hello and welcome to this PHP tutorial on the SWITCH statement.
|-
|0:06
|I'm going to show you a new exercise on this because its an important feature of PHP
|-
|O:13
|Let's create the syntax quickly
|-
|0:16
|The SWITCH statement is a substitute for the IF statement. Its a lot more neater and formattable choice although the input is an expression.
|-
|0:29
|So, now let's input the value of something and then let's save the value equal to this
|-
|0:36
|Then we can execute the code if it equals or matches this value
|-
|0:43
|It's not a comparing technique. So, for comparing an IF statement for matching values and outputs that depend on the input, we're going to say SWITCH
|-
|00:55
|Let's start
|-
|00:57
|SWITCH is the basic code for it
|-
|1:00
|Let's put an expression in here, for example, I will say Alex here
|-
|1:09
|Let's create a mini program and I will explain it as we go
|-
|1:15
|Just like the IFstatement we will put curly brackets here
|-
|1:21
|Now let's look at the way to call each sort of check
|-
|1:26
|We want to check the value here
|-
|1:29
|Now we will put this in quotation marks
|-
|1:32
|You can't even number obviously
|-
|1:35
|So what we type is - case - the value of the case that we want to match. For example- Alex
|-
|1:44
|Then we type a colon or a semi colon
|-
|1:48
|And then the condition if the case has matched with the SWITCH expression you have picked
|-
|1:56
|So, I will type - echo you have blue eyes
|-
|2:05
|To end our case comparison we're going to use break and a semi colon
|-
|2:11
|Remember that we've used the semi colon here but not here
|-
|2:18
|Now the second case. Lets see how to do it
|-
|2:23
|I'll type Billy and echo you have brown eyes
|-
|2:30
|Okay, and then break and semi-colon
|-
|2:36
|This is like an integrated IF. That is I could say - IF your name is Alex then echo you have blue eyes or ELSE IF your name is Billy you have brown eyes
|-
|2:53
|Probably for some people it's easy to do it this way. It's a lot more readable but it's a matter of choice
|-
|3:02
|Okay we got no more cases, I'm just going to use Alex and Billy for this example
|-
|3:10
|Here I will say default which will echo out - I don't know what color your eyes are
|-
|3:19
|Okay, we don't need a break after this because there are no more cases
|-
|3:26
|Obviously, there's no break after it cause there are no more options to chose from
|-
|3:34
|Okay, so, we've got our SWITCH here. Let's give it a go
|-
|3:39
|Now I'm going to replace this ALEX here with a variable, to build our program
|-
|3:46
|So I'll type name equals, and I will let you decide that
|-
|3:53
|Then I'll say name, here
|-
|3:57
|So you see this is how we incorporate a variable here
|-
|4:01
|You should know how to do that by now
|-
|4:04
|So, let's start and see how this will work
|-
|4:08
|You'll say switch, you'll take this expression, which is equal to Alex
|-
|4:13
|Basically, this is the case which equals to Alex and it'll echo this. The break is to end it
|-
|4:22
|If the name is say, Rahul, the default will echo - I don't know what colour your eyes are
|-
|4:29
|Okay, so let's try running this
|-
|4:37
|Just to revise
|-
|4:39
|We can see that Alex matches to Alex matches to the output
|-
|4:44
|What you can do is you can enter as many lines of code here as you like. This break determines where the case ends
|-
|4:54
|An IF statement needs curly brackets to end a block
|-
|4:59
|However, here break determines the end of the block. These are called blocks, by the way.
|-
|5:06
|So, let's change this to Billy and let's see what happens
|-
|5:10
|You have brown eyes - exactly what we determined here
|-
|5:16
|Okay, now I'll change this to Kyle.....and refresh, I don't know what colour your eyes are, because there is no block that states Kyle's eye colour in our program feature
|-
|5:31
|So, that's basically the SWITCH statement
|-
|5:34
|Try it out. Some people don't like using it, some prefer using it
|-
|5:38
|It's probably much faster than the IF statement. It's easier to control. It looks a lot better. So really its up to your personal choice
|-
|5:48
|Thanks for watching. This is Arvind for the Spoken Tutorial Project, signing off. Goodbye.
