Hi,
Please notice that I said "followed by required ones".
function foo($a = null, $b) {}
The above definition is allowed and the compiler won't complain, but
actually that "= null" is completely lost, including in Reflection.

Hi,
Actually PHP ignores default values on parameters followed by required
ones.
You can't fetch the default value even via Reflection.
This is easily detected at compile time so I wonder why the compiler
doesn't
warn.

I'm not sure this is what you mean, but I use the following function
in my debugging logic.
<?php
function getArgs($s_Function, array $a_PassedParams = array()) {
$a_Arguments = array();
if ('' !== $s_Function) {
$rf_This = new ReflectionFunction($s_Function);
foreach($rf_This->getParameters() as $i_Param => $rp_Param) {
$a_Arguments[$rp_Param->getName()] = $i_Param <
count($a_PassedParams) ? $a_PassedParams[$i_Param] :
$rp_Param->getDefaultValue() . ' (Default)';
}
}
return $a_Arguments;
}
function foo($required, $optional = 'snafu', $also_optional = 'sins') {
print_r(getArgss(__FUNCTION__, func_get_args()));
}
foo('fred');
foo('bob', 'jim');
outputs ...
Array
(
[required] => fred
[optional] => snafu (Default)
[also_optional] => sins (Default)
)
Array
(
[required] => bob
[optional] => jim
[also_optional] => sins (Default)
)
