preg-match-all

问题 Here is the sample string with my regex and code: $str = "Supp Fees: ---------- Oral Glucose Glucagon OXYGEN"; $ptn = "/----------(?:\r\n(.+))+/m"; preg_match_all($ptn,$str,$matches); echo"<pre>"; print_r($matches); echo"</pre>"; I'm trying to match every line after '----------' the pattern above only returns the first line (Oral Glucose). I can repeat the '\r\n(.+)' part and return another line but there is no telling how many lines there will be. Thanks! 回答1: You could do this without regex

问题 I try to get phone numbers from string in german format. But I don't get it to full run. The input text is a full HTML-Page with lots of content, not only the numbers.

问题 It is possible to get all content in nested curly braces from string? For example: The {quick} brown fox {jumps {over the} lazy} dog So i need: quick over the jumps {over the} lazy Better in this sequence, from most nested. 回答1: Solution The regex below will allow you to grab the content of all the nested curly braces. Note that this assumes that the nested curly braces are balanced; otherwise, it is hard to define what the answer should be. (?=\{((?:[^{}]++|\{(?1)\})++)\}) The result will be

问题 I am trying to come up with a regular expression in Perl matching multiple patterns and returning all of them like preg_match_all in PHP does. Here's what I have: $str = 'testdatastring'; if($str =~ /(test|data|string)/) { print "its found index location: $0 $-[0]-$+[0]\n"; print "its found index location: $1 $-[1]-$+[1]\n"; print "its found index location: $2 $-[2]-$+[2]\n"; print "its found index location: $3 $-[3]-$+[3]\n"; } This only gives me the first match which in this is 'test'. I

问题 I am trying to figure out the mechanics of this plugin in WordPress. I have a preg_match_all function that looks like this: preg_match_all('/(?<=\\[\\[).+?(?=\\]\\])/', $content, $matches, PREG_PATTERN_ORDER); $numMatches = count($matches[0]); for ($i = 0; $i < $numMatches; $i++) { $postSlug = $matches[0][$i]; } If I understand this correctly, count($matches[0]) assumes there is only one match in $content . My goal here is to re-write the for statement to allow for the full array of matches

问题 This question already has answers here : Get repeated matches with preg_match_all() (6 answers) Closed 10 months ago . Update/Note: I think what I'm probably looking for is to get the captures of a group in PHP. Referenced: PCRE regular expressions using named pattern subroutines. (Read carefully:) I have a string that contains a variable number of segments (simplified): $subject = 'AA BB DD '; // could be 'AA BB DD CC EE ' as well I would like now to match the segments and return them via

问题 Here is my concern, I have a string and I need to extract chraracters two by two. $str = "abcdef" should return array('ab', 'bc', 'cd', 'de', 'ef') . I want to use preg_match_all instead of loops . Here is the pattern I am using. $str = "abcdef"; preg_match_all('/[\w]{2}/', $str); The thing is, it returns Array('ab', 'cd', 'ef') . It misses 'bc' and 'de' . I have the same problem if I want to extract a certain number of words $str = "ab cd ef gh ij"; preg_match_all('/([\w]+ ){2}/', $str); //
