To declare a variable it is sufficient to choose a name, through which the
variable will be identified, and then initialize it. It is not necessary, as
it happens for other programming languages, to declare the type of the
variable. PHP is able to deduce the type of a variable from the value with
which it has been initialized. For instance, if we write
$var1 = 7;
PHP will create a variable of integer type with the name ' *$var1* ' and
store the value of *7* in it.
If instead we write
$var2 = "This is a variable";
PHP will create a variable of string type named ' *$var2* ' and store the
value "*This is a variable*" in it.
The type of a variable indicates what kind of data the variable will store.
The concept of datatypes is particularly important, not only in PHP, but in
all programming languages.
