|Hi and welcome to a basic PHP tutorial.
|-
|0:03
|I'll just go through how to use the "echo" function and how to set up your tags .
|-
|0:08
|Those of you that are familiar with "html" will know that there are html tags to start your page and to end your page.
|-
|0:15
|They're not vital in an html page. As long as you've got an html extension, you're fine.
|-
|0:20
|However, in PHP, you need the tags. This starts and this ends.
|-
|0:25
|That's basically the standard notation for it.
|-
|0:29
|However, our content goes in between here.
|-
|0:32
|Now, I've already saved my file as "helloworld.php".
|-
|0:36
|So, let's save that and have a look in here.
|-
|0:41
|Okay, there's nothing in the page at the moment but we've got our page set up. It's absolutely fine.
|-
|0:47
|The "echo" function works like this: we've got echo, we've got some double quotes and we've got a line terminator which is the semicolon mark.
|-
|0:57
|And our text goes in between here. Let's save that and we'll refresh. And there we go.
|-
|1:05
|Right, you can – and I find this very useful – write your "echo" function like this.
|-
|1:10
|Because when you put an html code inside your echo function (and just to let you know, if you haven't learnt html yet I suggest you pick it up, at least the basics, because we're going to be using it quite a lot) these bits here don't represent line breaks.
|-
|1:22
|For that you need to add your own html in. So '<br>' for line break and then 'New line'.
|-
|1:28
|We'll refresh this and there you go! Our html has been incorporated.
|-
|1:33
|Okay, just to let you know, this is one thing that a lot of people run into: 'image source equals' and your file goes there.
|-
|1:42
|However, at the moment we've got 'echo'.
|-
|1:46
|This shows that we're going to start our output and this here will show that we're ending our output.
|-
|1:52
|We don't end it here; we're going to end it here.
|-
|1:55
|So instead of these, we'll need inverted commas.
|-
|1:58
|Basically, that will let us show our image there.
|-
|2:02
|There's no file specified, but you get the picture.
|-
|2:05
|So, let me just show you what would happen if we keep these in and then with that I'll end the tutorial.
|-
|2:13
|Right, we've got 'Parse error'.
|-
|2:15
|We either need a comma or a semicolon to end, which proves that as we're coming up to here, we need a semicolon after this.
|-
|2:23
|But in actual fact, that's not true.
|-
|2:25
|So, just keep them as inverted commas.
|-
|2:30
|Okay, that's the basics of the echo function and the PHP tags. Hope you enjoyed learning them.
