正确的语法执行“数组”变量作为一个函数？

Question

I have the following array:

$bla = array (
   'function1', 'function2'
);

Assume the following function exists:

function1

How would I call it using the variable? This doesn't work:

$bla[0]();

What is the correct syntax?

Update

Also, what is the correct way to call it if the function has parameters?

Answer 1

You can use the call_user_func function:

call_user_func($bla[0]);
