Previous Comments: ------------------------------------------------------------------------ [2009-07-26 08:33:38] alan at hcibook dot com Description: ------------ The last of the example strings below should be "ababba" The string "ababaa" does not match as the pattern for the previous (2nd) iteration is "ba", hence to match b\1 on the third iteration, the rest of the string needs to be "bba" other matching strings "abaaba" "abaaababba" "ababbabbba" Reproduce code: --------------- --- From manual page: regexp.reference.back-references --- For example, the pattern (a|b\1)+ matches any number of "a"s and also "aba", "ababaa" etc. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=49062&edit=1
