Work with variables PHP
Work with variables in PHP is easy.
If you need a sum of numbers – use “+”
If we concatenate two lines – use “+”
$x = 3;
$y = 4;
$z = $x + $y;
$i = "Hello";
$y = "World";
$k = $i + $k;
Learn, develop, play.

Variables in PHP are defined very simply. It is not necessary to define the types of variables.
all that you need write next
Here we define a variable like 4
Now like string.
To show this variable you can write this lines
So it’s time to start writing about PHP
Now we’ll write the first line of code in PHP.
[cc lang=”php”]
[/cc]
And now look at the code
< ? php – this is a sign for the server: the PHP code starts
echo “Hello world! This my first program!”; – echo command says display string.
? > – this is a sign for the server: the PHP code ends
