Subject: [PHP-DEV] What is the use of the $replacement
property in the RegexIterator class.

Hi.

I'm in the process of getting the PHPDoc classes showing the
correct inherited properties and methods (public/protected
but not private).

I picked RecursiveRegexIterator (it has the largest number of
xi:includes in the documentation) as a test.

Using php --rc I see that the inheritance chain is
RecursiveRegexIterator, RegexIterator, FilterIterator and
IteratorIterator.

The property $replacement is part of RegexIterator.

I can see no documentation for this in phpdoc, nor in the
Doxygen at http://www.php.net/~helly/php/ext/spl/

In all the examples I've made so far, var_dump()-ing the
RegexIterator results in a ["replacement"]=>NULL

Assigning a value to $replacement seems to have no bearing on
the output.

Regards,

Richard.

Does seem odd public property. Guessing it's a bug.

I believe the intention was to give that property a value which could
be used with RegexIterator::REPLACE mode but that particular mode has
not yet been fully implemented. There is a related bug (
http://bugs.php.net/50579 ) that has not been assigned; I can't say
what the plan is for if/when the replacement mode will get some
attention. See also: the PHP implementation of RegexIterator (
http://svn.php.net/viewvc/php/php-src/trunk/ext/spl/internal/regexiterator.inc?view=markup
).

Regards,

Richard.
