Interface: Since we all knows that PHP does not support the
multiple inheritance. But don't worry we have an excellent
idea to do the multiple inheritance in php is Interface.
Interface is just like a class using interface keyword and
contains only function declarations(function with no body).
function is defined in the classes where you call it.

Ex:-

interface FirstInterfName{
function Add();
function Sub(10,5);
}

interface SecondInterfName{
function glbfunc1();
function glbfunc2();
}


class ClassName implements FirstInterfName,SecondInterfName
{
fuction Add()
{
$a = 5;
$a = $a + 1;
echo $a;
}

fuction Sub($a,$b)
{
$c = $a -$b;

echo $c;
}

function glbfunc1()
{
Implements here method...............
}

function glbfunc2()
{
Implements here method...............
}

}
