When parsing XML, PHP has no way to set a handler for general entities, though a 
handler can be set for unparsed entities.

Expat has deprecated the XML_SetUnparsedEntityDeclHandler in favor of 
XML_SetEntityDeclHandler, which is called for all entity types (including general 
and unparsed).

PHP should add the xml_set_entity_decl_handler function to allow handling of all 
entity declarations.

Test script:
$data = '<!DOCTYPE test [<!ENTITY generalEntity "General Entity">]><test>&generalEntity;</test>';

function h_entity_decl($parser,$entity_name,$is_parameter_entity,$value,$base,$system_id,$public_id,$notation_name) {
	echo "$entity_name - $is_parameter_entity - $value";

$parser = xml_parser_create();
xml_set_entity_decl_handler($parser, 'h_entity_decl');

xml_parse($parser,$data,false) or 
    die (sprintf("XML Error: %s at line %d<br>\n", 

Expected result:
It should run with the following output:

generalEntity - 0 - General Entity

Actual result:
Fatal Error: Call to undefined function xml_set_entity_decl_handler()

I've added a patch for this but I'd like to write a few more tests before committing it. If you could apply it and let me know if this helps you that'd be
