ID: 37913 User updated by: tom at foreignproperty dot com Reported By: tom at foreignproperty dot com -Status: Bogus +Status: Open Bug Type: Documentation problem PHP Version: Irrelevant New Comment: look at the array keys. it goes $matches[0], $matches[1], then jumps to $matches[3] and $matches[4] Shouldn't part 2 be matches[2], and part 3 be $matches[3]?
