A variable starts with the

$

sign. For instance:

$firstname = "Levani"; 
$lastname = "Makhareishvili";
$age = 19;

• Assignment Operator (=) is used to assign the value to a variable. • the variable $firstname will hold the value "Levani", • the variable $lastname will hold the value "Makhareishvili" and so on. To output the variable on the screen, we write the name of the variable:

echo $age;

When we want to output the value of the variable together with the text, we write the name of the variable in double quotes or after the text we write a comma or a dot and then the name of the variable:

echo "My name is $firstname $lastname, I am $age years old";
echo "My name is ",$firstname," ",$lastname,", I am ".$age. " years old.";

! PHP statements end with semicolons (;).
