Class is nothing but binding the data. I’e variables and functions. In class we can have number functions. Class can be declare with a key word class followed by a class name, which can be any name. This name should not be key word in php. Followed by a pair of curly braces .
Its recommended to start class name with a capital letter. And functions with a small letter. Before class declarations we can use modifiers I’e public, abstract. If access modifier is nothing by default it will take defaultft modifier..

public class Demo{

$i=0;

function myfristfunction(){

$i++;

echo $i;

echo "this my first function ";

}

function mysecondfunctin(){

$i++;

echo $i;

echo "mysecond function";

}

}

output:
1 this my first function 2 mysecond function

class Second{

function mysecondclass(){

echo "this is my second class";
}

}

output:

this is my second class
