Here's how you use it (and this has nothing to do with OOP.. it's just a function that says whether the given object has the given method).

I suggest reading the PHP manual at php.net or getting a book. But, just to answer this new question, $b is a variable in that scope (which I am assuming is inside a class member function), not a property. Code: $this->b = "lick"; how check method exist - El Forum - 10-24-2008 [eluser]Colin Williams[/eluser] Oh.. and you're right. I absolutely do use the restroom on occasion. how check method exist - El Forum - 10-24-2008 [eluser]minhbu[/eluser] No i have a controller demo class Demo extends Controller{ function demo() { parent::Controller(); } function index() { $id=$this->uri->segment(3); if(method_exists($this,$id)) $this->$id; else echo "Your method haven`t got"; } function a() { echo "Hello"; } } I have URI http://localhost/demo/index/a but i have a error A PHP Error was encountered Severity: Notice Message: Undefined property: Demo::$id Filename: controllers/demo.php Line Number: 20 how check method exist - El Forum - 10-24-2008 [eluser]Colin Williams[/eluser] You are calling a function, so you need parenthesis Code: function index() |
