Edit report at https://bugs.php.net/bug.php?id=34121&edit=1 ID: 34121 Updated by: kalle@php.net Reported by: nlopess@php.net Summary: Add DFA support to preg_match() function -Status: Assigned +Status: Open Type: Feature/Change Request Package: PCRE related Operating System: * PHP Version: * -Assigned To: andrei +Assigned To: Block user comment: N Private report: N Previous Comments: ------------------------------------------------------------------------ [2005-08-15 20:52:09] nlopess@php.net OK, patch revised. I've added support for partial matching. This can be usefull, for example, in a CLI app to beep when a user enters a bad char (by doing partial matching when a new char comes in). TODO: make preg_match_all() fetch all the data (instead of the hardcoded limit). this may be tricky. ------------------------------------------------------------------------ [2005-08-13 14:21:46] nlopess@php.net Assigning to Andrei, as he's the PCRE extension maintainter. ------------------------------------------------------------------------ [2005-08-13 14:20:51] nlopess@php.net Description: ------------ I've made a patch to add DFA (PCRE 6) support to preg_match(). It isn't completed (yet), because I would like to receive your feedback first before continuing. patch: http://mega.ist.utl.pt/~ncpl/php_pcre_dfa.txt example: http://mega.ist.utl.pt/~ncpl/dfa_example.php TODO: - currently preg_match_*() allocs memory for captures based on the number of capturing parentheses. But this needs to be changed for the DFA mode. - make partial matching working. The only thing it needs to be done is to save the workspace table in the cache and reuse it when calling the pcre_dfa_exec() function. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=34121&edit=1
