PHP Bug Type: Zend Engine 2 problem
Bug description: zend_parse_parameters() doesn't coerce overloaded objects into
strings
Description:
------------
When passing an object with a __toString() method to a
function that uses zend_parse_parameters() with an "s"
value, PHP does not correctly coerce the object into a
string.
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.
