Is there a "clean" way to make use of PHP builtins that use callbacks and
point those call backs to a method inside the class/object:
A good example would be:
...
class XMLClass {
var $parser;
function XMLClass() {
$this->parser = xml_parser_create();
xml_parser_set_option($this->parser, XML_OPTION_CASE_FOLDING, TRUE);
xml_set_element_handler($this->parser, "$this->start", "$this->end");
xml_set_character_data_handler($this->parser, "$this->data");
}
function goodbye() { // a manual destructor
xml_parser_free($this->parser);
// other things possibly too
}
function start($p2, $name, $attr) {
// do things here
}
function data($p2, $data) {
// do some more here
}
function end($p2, $name) {
// do even more things here
}
[... and so on ...]
...
But since there is no way to set a callback to "$this->[function_name]" one
must create a global function that uses a global object and passes things to
the method inside the class..
Is the a way to address this? or perhaps a better way to deal with callback
function names?
