Properties:
- public replacement
Methods:
- RegexIterator::__construct(Iterator it, string regex [, int mode [, int flags [, int preg_flags]]]) - Create an RegexIterator from another iterator and a regular expression
- bool RegexIterator::accept() - Match (string)current() against regular expression
- bool RegexIterator::getFlags() - Returns current operation flags
- bool RegexIterator::getMode() - Returns current operation mode
- bool RegexIterator::getPregFlags() - Returns current PREG flags (if in use or NULL)
- bool RegexIterator::setFlags(int new_flags) - Set operation flags
- bool RegexIterator::setMode(int new_mode) - Set new operation mode
- bool RegexIterator::setPregFlags(int new_flags) - Set PREG flags
RecursiveRegexIterator

Constants:
