|Welcome to a basic tutorial on PHP variables.
|-
|0:04
|Let me quickly go through a few things first.
|-
|0:07
|PHP variables are very easy to use; I'm sure you'll understand them straight away.
|-
|0:14
|You don't need to declare them and they're quite easy to write.
|-
|0:18
|You can add a value to a variable half way through the script.
|-
|0:23
|Also, they automatically convert to the data type you require.
|-
|0:28
|So there's no need to declare them in a different way each time, or create a value for them each time.
|-
|0:36
|So, for example, let's create our PHP tags here and our content goes in between.
|-
|0:41
|Okay. Now we start with the dollar sign and then we have our variable name.
|-
|0:48
|Please note that you can't start with a "number". So I can't start with a '1'.
|-
|0:53
|What I can start with is an "underscore" or a "letter".
|-
|0:57
|No other special characters are allowed except underscores, letters and numbers, as long as it doesn't start with a number.
|-
|1:06
|So that would be perfectly acceptable here.
|-
|1:09
|Okay, so I'll create a variable called "name" and that's going to be equal to a string value contained within double quotes, just like we used for the "echo" function.
|-
|1:21
|'My name is Alex'.
|-
|1:23
|On the next line, we're going to create another variable using a dollar sign, called 'age'. That's going to be equal to '19', without double quotes.
|-
|1:33
|Now the reason for this is that this is an integer.
|-
|1:36
|You can use it for decimal values as well. So this could be '19.5' or nineteen and a half.
|-
|1:43
|That would also automatically convert this into a decimal.
|-
|1:48
|However, at the moment it's just an integer. That's how I want it - the variable 'name' is a string and the variable 'age' is an integer.
|-
|1:57
|So let's try echoing these out.
|-
|2:00
|What we need is "echo" and the variable name, not forgetting your line terminator.
|-
|2:06
|Okay, let's find our file named "variables".
|-
|2:11
|Okay, "Alex" has been echoed out, just like I've said here, "echo name".
|-
|2:16
|Let's try and echo out my age now.
|-
|2:19
|It's just an integer variable and that's been echoed out here.
|-
|2:24
|Okay so, the thing with variables is that they're very easy to concatenate into a string.
|-
|2:30
|In fact, probably, concatenation is the wrong word – they're very easy to include inside your string.
|-
|2:37
|If you don't know what concatenation is, it just means to join two things together or to join two strings together in a line.
|-
|2:46
|So, an example of concatenation would be, let's see, 'concat' and then I could say, '.' and then 'ination'.
|-
|2:56
|Now, this would echo out 'concatination'.
|-
|2:59
|Let's try this. Okay?
|-
|3:03
|But there is a completely different tutorial on that. So, what I'll say is, for now, you don't need to include this as one of your variables when you're echoing it out.
|-
|3:14
|If you can't follow this, don't worry. This is very, very simple.
|-
|3:18
|I'll say "My name is" name "and my age is" and put my age down.
|-
|3:24
|Now, it's all in one string, all in one echo, and we've just got 'My name is' – plain text.
|-
|3:32
|Variable is called. This is put here. And then when age is called, the value for age is put here.
|-
|3:40
|So, we can refresh that and you can see that "My name is Alex". That's our variable. "and my age is 19" and that's our variable.
|-
|3:48
|So they're really easy to put into strings.
|-
|3:52
|Okay, this is all you really need to know about variables.
|-
|3:56
|There are other types of variables, like boolean, decimal – which I've shown you, for example like '19.5'.
|-
|4:06
|You would declare them in the same way, with a dollar sign.
|-
|4:10
|So practice this and you can come back and learn some more advanced functionality later on, when I'm going through some other projects.
