PHP Bug Type: Scripting Engine problem
Bug description: Reflection API problems in methods with boolean or null
default values
Description:
------------
This problem came up when moving our homebrew 'PHPDoc' type class to
PHP5.1. When built with --enable-debug PHP throws up warnings up when the
class to be documented ('A' below) contains methods with default values
that are either NULL or boolean
In the code snippet below we get two warnings, one for each default
parameter. Changing the default values to a string or number (even zero)
eliminates the warnings.
This is a serious problem for us. When documenting some of our bigger
classes we have seen lots of 'odd' behaviour, including permanent 100% CPU
usage by Apache! It has taken *days* to track down the problem to the
snippet below. If there is anything elso I can do to help fix it please
let me know...
Reproduce code:
---------------
$r = new ReflectionClass('A');
$methods = $r->getMethods();
foreach($methods as $method)
{
$parameters = $method->getParameters();
foreach($parameters as $p)
{
if($p->isDefaultValueAvailable())
$p->getDefaultValue();
}
}
class A
{
function foo($p=null, $q=false)
{
}
}
Expected result:
----------------
No output at all -- I've trimed all the output code out.
Actual result:
--------------
