Hello.
Here we go again. Delete my old entry if you wish.
Trying to port a parser from C++ to PHP I came across that PHP doesn't support multiple
constructors. I believe PHP lacks the possibility to create new objects out of different types of
information without writing specialized functions.
An example, which does not work:
<?php
class DocNode{
function __construct(DocNode $copyfrom, DocNode $parent = null, DocNode $insertAfter = null){ /*
... */}
function __construct($type = 'text', $collapsable = false){ /* ... */}
}
?>
If you run that, you would get:
Fatal error: Cannot redeclare DocNode::__construct()
I guess one could fallback to passing an array to the constructor and inside the constructor
determine what to make of that array, and so in a workaroundish way have multiple constructors all
in one constructor.
