get_class function (PHP 4, PHP 5)

get_class — Returns the class name of the object

Report a bug reject note description

string get_class ([ object $obj ] ) Returns the name of the class to which the object instance obj belongs. Returns FALSE if obj is not an object.

Note: Classes defined in PHP extension libraries return the name of their original definition. In PHP 4 get_class() returned the lowercase form of the user-defined class name, but in PHP 5 it will return the name of the class name as it was defined, just like the class name in the extension library.

Note: Since PHP 5, obj is optional if called within a method of an object.

Example 1, using get_class()

  1. class foo {

  2. function foo()
  3. {
  4. // implements some logic
  5. }

  6. function name()

  7. {
  8. echo "My name is " , get_class($this) , "n";
  9. }
  10. }

  11. // create an object

  12. $bar = new foo();
  13. // external call

  14. echo "Its name is " , get_class($bar) , "n";

  15. // internal call

  16. $bar->name( );
  17. ?>

Copy the code

output: Its name is foo My name is foo
