PHP Basics Welcome to the php basics tutorial! In this tutorial we will help you understand how to use php.

First off, you need to know how to open php tags and close them.

Code:

Thats opening a tag.

Code:

And thats closing a tag.

All you're php work goes inside those tags.
Now, if you want to print something onto the page you use this.
Code:

echo 'Hello world!';
?>

That would output the words Hello world.

Next we are going to create a variable.
Variable's hold data.
For example:
Code:

$variable = 'Hello world!';
echo $variable;
?>

As for checking we would use an if statement.
Code:

$one = 1;
$two = 2;
if($one==$two){
echo 'one is equal to two.';
}
else{
echo 'one is not equal to two.';
}
?>

what this does is it checks if the data in variable $one is the same as the data in variable $two.
If it was it would have output one is equal to two but because it isnt, the else statement returned one is not equal to two instead.
