| 00:01 | Hi and welcome to a basic PHP tutorial. |
| 00:05 | I'll just go through how to use the "echo" function and how to set up your tags . |
| 00:10 | Those of you that are familiar with "html" will know that there are html tags to start your page and to end your page. |
| 00:18 | They're not vital in an html page. As long as you've got an html extension, you're fine. |
| 00:25 | However, in PHP, you need the tags. This starts and this ends. |
| 00:30 | That's basically the standard notation for it. |
| 00:34 | However, our content goes in between here. |
| 00:39 | Now, I've already saved my file as "helloworld.php". |
| 00:43 | So, let's save that and have a look in here. |
| 00:47 | Okay, there's nothing in the page at the moment but we've got our page set up. It's absolutely fine. |
| 00:54 | 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. |
| 01:03 | And our text goes in between here. Let's save that and we'll refresh. And there we go. |
| 01:09 | Right, you can – and I find this very useful – write your "echo" function like this. |
| 01:16 | Because when you put an html code inside your echo function, these bits here don't represent line breaks. (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). |
| 01:34 | For that, you need to add your own html in. So for line break and then 'New line'. |
| 01:43 | We'll refresh this and there you go! Our 'html' has been incorporated. |
| 01:48 | 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. |
| 01:57 | However, at the moment we've got 'echo'. |
| 02:01 | This shows that we're going to start our output and this, here, will show that we're ending our output. |
| 02:07 | We don't end it here; we're going to end it here. |
| 02:11 | So instead of these, we'll need inverted commas. |
| 02:14 | Basically, that will let us show our image here. |
| 02:18 | There's no file specified but you get the picture. |
| 02:21 | So, let me just show you what would happen if we keep these in and then with that I'll end the tutorial. |
| 02:28 | Right, we've got Parse error. |
| 02:31 | 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. |
| 02:40 | But in actual fact, that's not true. |
| 02:42 | So, just keep them as inverted commas. |
| 02:45 | Okay, that's the basics of the echo function and the PHP tags. Hope you enjoyed learning them. |
