Question

I made a function like this (no need to write the whole function here) :

public function selectNode($from, $attributes = null, $childs = null)

and, of course, if I call it this way :

$node->selectNode();

The argument $from isn’t initialized and then you got a warning error.
I know you can suppress the error doing @$node->selectNode(); or something like that thanks to @.

But, I want to handle it myself. How can I do that if that’s possible?

The only way I found is to initialize it like this public function selectNode($from = null, $attributes = null, $childs = null) but that doesn’t make it clear ($from is not an option as the others).

(And, of course, this function, here, is just an example. It could be extended to other functions)

Answer 1

You could use a try-catch block handling the error yourself.

try {
  $node->selectNode();
}
catch (Exception $e){
  echo $e; // do whatever you like here with error info $e, if you leave the parenthesis empty here nothing is done and the error message is suppressed
}
