Re: Getting Default Values via reflection.

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. Regards, Stan Vassilev

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. Regards, Stan Vassilev

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) ) -- ----- Richard Quadling Zend Certified Engineer : http://zend.com/zce.php?c=ZEND002498&r=213474731 "Standing on the shoulders of some very clever giants!" -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
