There are ways to dynamically add methods to an object at runtime but you would need to have a very strong case for doing so. If the fingerprint of the class is going to change at runtime then you may not be looking at OOP in the correct way.

In PHP 5.3, Lambda functions (and closures) are being introduced which allow creation of functions at runtime with a syntax much more similar to that seen in other languages. It has been possible to do this previously but you have to use the clunky create_function. There is a great overview of this new implementation at http://fabien.potencier.org/article/17/on-php-5-3-lambda-functions-and-closures

I must point out that the original draft for Lambda functions in PHP specifically said “This is not intended as a way to dynamically add methods to objects”

If you define a class yourself, there is a way to add functions dynamically, a great tutorial can be seen here.

If you’re bound to using the standard class (stdclass), you probably won’t be able to do what you want. An instance of the stdclass isn’t much more than an array with different syntax.

function fun1 (){
echo “Im fine”;
}

myObject->myMethod = fun1; //doesnt work

thanks

$myObject = new stdClass();

I can set a data member (property) as :

$myObject->myProperty = ‘hello world’;

how can I set a method?

Thanks.

note
the instinct way doesnt work.

function fun1 (){
echo “Im fine”;
}

myObject->fun1; //doesnt work

Sometimes these code syntax highlighters can insert strange characters. Can you explain exactly where it’s going wrong and I may be able to help.

I’ll try find time to zip up a copy too if I can.
