| 0:00 | Hi guys. This is a basic PHP tutorial. |
| 0:03 | I'm just going to run through how to use the echo function and how to set your tags up. |
| 0:08 | Right, those of you that are familiar with html, will know that there are your html tags to start your page, 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 your tags. This starts, this ends, and that's basically the standard notation for it. |
| 0:29 | However, our content goes in between here. |
| 0:32 | Right, I've already saved my file, that's 'helloworld.php'. |
| 0:36 | So, let's give that a save and have a look in here. |
| 0:41 | Right, 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 speech marks and we've got a line terminator which is the semicolon on your keyboard. |
| 0:57 | And, our text goes in between here. Let's save that out 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 slightly, because we're going to be using it quite a lot) these bits here don't represent line breaks, for that you need to add your own html in, so ' ' 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, what we've got at the moment is we've got 'echo', 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. So instead of these, we'll need inverted commas – basically, that will let us show our image there. 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 that's pretty much the end of the tutorial. |
| 2:13 | Right, we've got 'parse error' – 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 rubbish. So, just keep them as inverted commas. |
| 2:30 | Okay, that's the basics of the echo function and the PHP tags, that's all you really need to know for now. Thanks for watching! |
