using PHP via a class?

[beam1985]

My teacher just told me for my project that i need to use a class. I have no idea what a class in php is or how to utilize or implement one. can anyone paraphrase these instructions please? i have no idea what it means.

 

remember that we've been building everything as a class called

ReadWriteWeb:

 

class ReadWriteWeb {

      //methods and properties here

      var $variable  = array();

 

      function aMethod() {

 

      }

}

 

$mc = new ReadWriteWeb();

$mc->aMethod();

 

 

so, create new classes & use those instead of interleaving your php

with your html as you are now.

does this help (or confuse even more) ?
