Edit report at http://bugs.php.net/bug.php?id=52382&edit=1 ID: 52382 Comment by: giorgio dot liscio at email dot it Reported by: giorgio dot liscio at email dot it Summary: NULL in method arguments is casted to string? Status: Bogus Type: Bug Package: DOM XML related Operating System: all ? xp x64 PHP Version: 5.3.2 New Comment: i don't think that is like you think if i extend appendChild override appendChild($name, $content = NULL, $myNewArg = NULL) if i want to skip the second argument i can not or another issue: as php doc says DOMImplementation->createDocument ([ string $namespaceURI = NULL [, string $qualifiedName = NULL [, DOMDocumentType $doctype = NULL ]]] ) third parameter is optional (=NULL) but if i do $x->createDocument(null, null, null); to create an empty document exception is thrown: Argument 3 passed to DOMImplementation::createDocument() must be an instance of DOMDocumentType, null given if i do createDocument(); obviously works, but the concept of "skipping not required parameters with null" is not respected Previous Comments: ------------------------------------------------------------------------ [2010-07-20 09:59:01] aharvey@php.net They're not equivalent: you're providing a value for the "value" parameter to DOMDocument::createElement(), so yes, it will get coerced into an empty string using PHP's usual type juggling mechanism. ------------------------------------------------------------------------ [2010-07-20 09:46:25] giorgio dot liscio at email dot it Description: ------------ hi, test this: header("Content-Type: text/plain"); $doc = new \DOMDocument() $doc->appendChild($doc->createElement("root", NULL)); echo $doc->saveXML(); echo "\n\nshould be equivalent to:\n\n"; $doc = new \DOMDocument() $doc->appendChild($doc->createElement("root")); echo $doc->saveXML(); i hope other DOM methods will work good... otherwise fix is needed thank you! ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=52382&edit=1
