Static Functions in php
Static methods in PHP 5
In PHP 5, we can also define a method as static, which means that it is called on a class and not on an object. A static method has no access to any object properties and is created and accessed as in example :
Example
<?php
class User {
static function pwd_string() {
echo "Please enter your password";
}
}
User::pwd_string (); // Calling pwd_string (without object creation)
?>
Note how the class itself is called, along with the static method, using a double colon (also known as the scope resolution operator) and not ->. Static functions are useful for performing actions relating to the class itself, but not to specific instances of the class.
