在PHP中使用OOP时在方法中使用函数

Question

I need to know something about OOP in PHP.
Can I put functions in class methods or no ? Like this:

<?php
class test {
   function test1() {

      // do something

      function test1_1() {
         // something else
      }

   }
}
?>

And use it in this way: $test->test1->test1_1();

Answer 1

No you cannot. That would just create a new function in the global namespace and will give you errors of trying to redeclare the function when called multiple times.
