array_map not working in classes

Question

I am trying to create a class to handle arrays but I can\'t seem to get array_map() to work in it.

Answer 1

You are specifying dash as the callback in the wrong way.

This does not work:

$this->classarray = array_map($this->dash(), $data);

This does:

$this->classarray = array_map(array($this, 'dash'), $data);
