Introduction
In this tutorial, you will learn about PHP, i will start with this and then make more parts to it until i have completed a few parts which will cover the whole range of PHP. I hope you will learn lots from this tutorial and when you finish you will know loads. I have benefited from learning this way and that's why i have written it out as a tutorial for others to learn from.
Start Off PHP
Now to start off create a page with any name, it doesn't really matter. However you need to make the page end it .php
When you are using PHP, you need to define it and tell the page you are using it, so this is kind of like :
CODE
<html>
and
CODE
</html>
However in PHP, to start off a PHP script you use:
CODE
<?
or
CODE
<?php
and to close it you use
CODE
?>
In this case we will be using the first choice so inside your page place this code.
CODE
<?
?>
?>
Inside these brackets with question marks you can place any php stuff you like.
Echo
Then let's say you want to input some text, in PHP there are 4 ways
CODE
echo 'text';
print 'text';
return 'text';
die 'text';
print 'text';
return 'text';
die 'text';
(Note that die will shut down the rest of your script so nothing else below it will run, making it useful for errors and things.)
But for now you do not need to know them so we will be using echo.
So in between the brackets insert the echo which would look like this.
CODE
<?
echo "Hello";
?>
echo "Hello";
?>
You can also change the quotations to single's eg
CODE
<?
echo 'Hello';
?>
echo 'Hello';
?>
These both would show up like this:
CODE
Hello
but don't worry about that for now.
Variables
In PHP there are such things called variables, these define a certain object.
To cut it down into baby language imagine you have a file in your "My Documents" folder, then, placing the variable into a echo is like making a shorcut on your desktop.
In This example we will be changing the "Hello" text into a variable then place the variable into the echo to show on the page, i have broken this down into steps to explain it.
Step 1: Open the PHP brackets
CODE
<?
Step 2: Make a variable called greeting
CODE
$greeting = "";
Step 3: Define whats happening in the variable so in this case we would say we want text to show up saying "Hello"
CODE
$greeting = "Hello";
Step 4: Echo this variable
CODE
echo $greeting;
Step 5: Close the PHP Brackets
CODE
?>
So, altogether that would look like this:
CODE
<?
$greeting = "Hello";
echo $greeting;
?>
$greeting = "Hello";
echo $greeting;
?>
This to would end up looking like this on a page
CODE
Hello
That's the end for part 1, look out for part 2 where i will more like the if command and if..else command as well as more in depth explanations of PHP.
Enjoy!
