how can i find multiple occurrence of the same character? something like: $maxRepeat = 3; "pool" passes "poool" don't i need this to work for any character, so i guess I'll have to escape special characters like . and \ which characters i have to escape? do you know any good reference to preg_match regexp apart from the one on php.net?

This question already has an answer here: Regular expression to match a line that doesn't contain a word 29 answers Regular Expression block negation 1 answer To match any character except specified character (in this example "f") I use [^f]+ .

I've been searching for hours trying to find a solution to this. I am trying to determing if the REQUEST URI is legit and break it down from there. $samplerequesturi = "/variable/12345678910"; To determine if it is legit, the first section variable is only letters and is variable in length. The second section is numbers, which should have 11 total. My problem is escaping the forward slash so it is matched in the uri. I've tried: preg_match("/^[\/]{1}[a-z][\/]{1}[0-9]{11}+$/", $samplerequesturi) preg_match("/^[\\/]{1}[a-z][\\/]{1}[0-9]{11}+$/", $samplerequesturi) preg_match("/^#/#{1}[a-z]#/#{1}

I am having some trouble converting a php pregmatch to java. I thought I had it all correct but it doesn't seem to be working. Here is the code: Original PHP: /* Pattern for 44 Character UUID */ $pattern = "([0-9A-F\-]{44})"; if (preg_match($pattern,$content)){ /*DO ACTION*/ } My Java code: final String pattern = "([0-9A-F\\-]{44})"; public static boolean pregMatch(String pattern, String content) { Pattern p = Pattern.compile(pattern); Matcher m = p.matcher(content); boolean b = m.matches(); return b; } if (pregMatch(pattern, line)) { //DO ACTION } So my test input is: DBA40365-7346-4DB4-A2CF

I want to be able to parse file paths like this one: /var/www/index.(htm|html|php|shtml) into an ordered array: array("htm", "html", "php", "shtml") and then produce a list of alternatives: /var/www/index.htm /var/www/index.html /var/www/index.php /var/www/index.shtml Right now, I have a preg_match statement that can split two alternatives: preg_match_all ("/\(([^)]*)\|([^)]*)\)/", $path_resource, $matches); Could somebody give me a pointer how to extend this to accept an unlimited number of alternatives (at least two)? Just regarding the regular expression, the rest I can deal with. The rule
