[PHP] Remove Dynamic String between StringA and StringB
Hi :), i tried your code zu replace some parts of a string, the problem is that this method only replaces when there is only 1 word between stringA and stringB. i got the problem that the part between both strings is a dynamic one and much larger then 1 word. i really tried to use the php manual and google to find some help for this, but i got no luck with that :( $stringA = AA; $stringB = BB; $string = AA oneword BB AA two words BB; $pattern = /$stringA.\w*.$stringB/; $replacement = ; echo preg_replace($pattern, $replacement, $string); i think it have to do something with the \w in the pattern, is there a parameter to resolve my problem too? regards manuel -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Remove Dynamic String between StringA and StringB
$pattern = /$stringA.*?$stringB/; .*? - matches everything between $stringA and $stringB the ? means: stop matching after the first occurence of $stringB (quantifier minimizer). otherwise .* would match everything between the first occurence of $stringA and the last occurence of $stringB - http://ch2.php.net/manual/de/pcre.pattern.syntax.php g. tinu Tue, 27 Jan 2004 13:25:27 +0100 Jack Bauer [EMAIL PROTECTED]: Hi :), i tried your code zu replace some parts of a string, the problem is that this method only replaces when there is only 1 word between stringA and stringB. i got the problem that the part between both strings is a dynamic one and much larger then 1 word. i really tried to use the php manual and google to find some help for this, but i got no luck with that :( $stringA = AA; $stringB = BB; $string = AA oneword BB AA two words BB; $pattern = /$stringA.\w*.$stringB/; $replacement = ; echo preg_replace($pattern, $replacement, $string); i think it have to do something with the \w in the pattern, is there a parameter to resolve my problem too? regards manuel -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Of course. \w* will match alphanumeric characters, but not whitespace, and word boundaries are typically whitespace. i really tried to use the php manual and google to find some help for this, but i got no luck with that :( It's not a question of luck; it's a question of investing a little of your time in reading and learning. You don't want to spend your time doing that but expect other people to spend theirs providing you with all the answers you need. You've been given a few pointers (such as the online introductory guide to regular expressions, which will tell you everything about matching word characters, non-word characters etc etc) but don't seem to have taken any interest in them, because of course that would mean you'd have to actually spend an hour or so of your valuable time doing some reading. Bear in mind that other people's time is *also* valuable. i think it have to do something with the \w in the pattern, is there a parameter to resolve my problem too? Go to http://msdn.microsoft.com/library/en- us/script56/html/js56reconIntroductionToRegularExpressions.asp and read it, especially the Regular Expression Syntax section. After doing that, read the relevant part of the PHP manual. Things will start to make sense soon enough.

I'm not sure I understand you correctly, but it seems to me that you need to use regular expressions. You haven't provided us with an example or with strings A and B, so it's kinda difficult to give you any specific help. Suggestion: read up on Regular Expression Functions (Perl-Compatible) in the PHP manual (chapter XC in the Function Reference section). If you're not familiar with regular expressions and find the PHP manual too difficult as a starting point, you'll find a pretty good introductory guide, courtesy of the Dark Side of the Force, at http://msdn.microsoft.com/library/en-us/script56/html/js56reconIntroducti onToRegularExpressions.asp Have fun, Erik -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
