lt a href  home php click 1  class  btn  gt Click me lt  a gt   lt  php    if   GET  click         doSomething          gt    But is better to use JS and with ajax to call function

You are trying to call a javascript function  If you want to call a PHP function  you have to use for example a form        lt form action  action page php  gt         First name  lt br gt          lt input type  text  name  firstname  value  Mickey  gt          lt br gt         Last name  lt br gt          lt input type  text  name  lastname  value  Mouse  gt          lt br gt  lt br gt          lt input type  submit  value  Submit  gt        lt  form gt      Original Code from  http   www w3schools com html html forms asp   So if you want do do a  asynchron call  you could use  Ajax  - and yeah  that s the Javascript-Way  But I think  that my code example is enough for this time
