#43328 [Com]: About the bugs #42590, #43316

ID: 43328 Comment by: carsten_sttgt at gmx dot de Reported By: dagdamor at simps dot ru Status: Open Bug Type: Strings related PHP Version: 5.2.5 New Comment: > Check carefully the table 11.1 I confirm with you, "\v" and "\f" are no valid escape sequences, according to the PHP manual. Thus a PHP programer must not take care about this escape sequences. Especially for existing scripts. Just a additinal question: PCRE nows the escape sequence "\f". Correct, you can read this in the PHP manual [1]. But what's about "\v"? Here I have this informations: | Perl 5 no longer includes vertical tab in its set of whitespace | characters. | The \v escape that was in the Perl documentation for a long time | was never in fact recognized. Of course, on my system (PHP5.2.5/Win, PCRE compiled by PHP), a "\v" matches: "LF, VT, FF, CR"?

Check carefully the http://www.php.net/manual/en/language.types.string.php, table 11.1, and what's written right after it. One should think a little bit before making fundamental changes in the parser and breaking BC *that* much... >:| ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=43328&edit=1
