Decalring Vars / Default Values


Recommended Posts

What is the difference between declaring values at the top of a class versus in between the parenthesis of a method?


Class MyClass {

      private $table = 0;
      public   $field = "name";

      // etc...



Class MyClass {

      private $_table;
      public $field;

      public function myFunction($_table=0, $field="name") {}

*** oops sorry about that didn't mean to submit just that...here's the rest


When you declare the variables at the top of the class you are preparing them to be used anywhere in the class.


In the function declaration you are setting them as if they were local variables being passed for that function.

Class MyClass {

      private $_table = 1;
      public $field = "name";

      public function myFunction($_table=0) {
        echo $_table; // 0
        echo $this->_table; // 1
        echo $field; //
        echo $this->field; // name
