I have a bunch of functions depending on a variable, I want to be able to do something like this:
(It returns an error hence the problem I'm unable to solve)
function($x) {
fetch.$x.() // if x=Name I would like it to execute fetchName()...and so on
}
and something like this
function($x) {
$article = new \Cc\WebBundle\Entity\$X();
// if x='name' to be executed Cc\WebBundle\Entity\name()
}
Sure, you could do that:
$basename = "fetch";
$key = ...; // your logic for generating the rest of function's name
$functionName = $basename . $key;
$functionName(); // execute function
Now, the tricky part would be if functions contain arbitrary set of arguments. In that case you should use call_user_func_array (docs).
As for creating of objects, meagar explained here please clear how to achieve that.
P.S. This, in fact, has very little to do with Symfony2. This is a pure PHP question ;)
Personally, I use the handy call_user_func_array() function like this:
<?php
$class = 'MyClassName';
$method = 'someMethod';
$parameters = array('foo', 'bar', 'baz');
call_user_func_array(array($class, $method), $parameters);
I imagine you would need to escape back-slashes in any name-spaced class names though, i.e. MCB\\MyClassName.
