This occurs for both extensions (like SimpleXML) and user-defined PHP classes. Reproduce code: --------------- class foo { function __toString() { return "foo"; } } $foo = new foo; print strrev($foo) ."\n"; print htmlspecialchars($foo) ."\n"; Alternatively: $xml = '<?xml version="1.0" ?><root><element>text</element></root>'; $s = simplexml_load_string($xml); print strrev($s->element) ."\n"; print htmlspecialchars($s->element) ."\n"; Expected result: ---------------- oof foo Actual result: -------------- PHP Warning: htmlspecialchars() expects parameter 1 to be string, object given in foo.php on line 10 oof strrev() uses convert_to_string_ex(), so it works fine. htmlspecialchars() uses zend_parse_parms(), so there's a warning. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=26265&edit=1
