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.
02:52 Thanks for watching! This script has been translated by ---------------------------(translator's name) and this is -----------------------------------(narrator's name) signing off.
