Previous Comments: ------------------------------------------------------------------------ [2015-05-27 22:59:12] cmb@php.net I agree that the wording of the documentation is unfortunate: | SimpleXML objects created from empty tags An empty tag would most likely be something like <>. Speaking of empty elements would be better, but would not take into account that an empty element may have attributes (not properties), and in this case casting the respective SimpleXML to bool would also yield true. ------------------------------------------------------------------------ [2014-12-03 10:47:56] seo at gacek dot vot dot pl Description: ------------ --- From manual page: http://www.php.net/language.types.boolean --- Documentation needs some more information, to clarify when simplexml object is considered true. More information here: http://stackoverflow.com/a/27157104/1430632 Tried adding it to documentation <warning> <simpara> <literal>SimpleXML</literal> evaluates to &true; only if it has child nodes or properties - only then object is not considered empty. To check if <literal>SimpleXML</literal> object has &string; value you have to cast it to &string; </simpara> </warning> ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=68540&edit=1
