preg-match

问题 I need help with a REGEX that will find a link that comes in different formats based on how it got inserted to the HTML page. I am capable of reading the pages into PHP. Just not able to the right REGEX that will find URL and insulate them. I have a few examples on how they are getting inserted. Where sometimes they are plain text links, some of wrapped around them. There is even the odd occasion where text that is not part of the link gets inserted without spacing. Both Article ID and

问题 I am trying to return a series of numbers between 5 and 9 digits long. I want to be able to get the longest possible match, but unfortunately preg_match just returns the last 5 characters that match. $string = "foo 123456"; if (preg_match("/.*(\d{5,9}).*/", $string, $match)) { print_r($match); }; will yield results Array ( [0] => foo 123456 [1] => 23456 ) 回答1: Since you want only the numbers, you can just remove the .* from the pattern: $string = "foo 123456"; if (preg_match("/\d{5,9}/",

问题 I store a list of of bad words I want to filter posts against before I store them in the database. I store the bad words in an array that I implode with a pipe delimiter to do the check once. $bad_words_regex = "/\b" . implode('|', config_item('bad_words')) . "\b/"; if( preg_match(strtolower($bad_words_regex), strtolower(trim($message))) == FALSE ) { // save to database } I noticed messages with commas did not get saved to the database. I imagine there are other characters I should check for

问题 I'm using the Segment router as a child of one of my main Literal routes in a ZF2 (currently using 2.3.5) application. The router needs to be able to handle Turkish input characters coming in from the URL. My first attempt looked something like this (as a child route): 'book' => array( 'type' => 'Zend\Mvc\Router\Http\Segment', 'options' => array( 'route' => 'kitap/:book[/]', 'constraints' => array( 'book' => '[a-zA-ZçÇşŞğĞıİöÖüÜ1-3.+ ]+', ), ), ), This mostly worked for everything I needed it

问题 I am trying to extract the latitude and longitude of a google maps url. Such an url could look like this: $url = 'http://maps.google.com/?ie=UTF8&ll=39.811856,11.309322&spn=0,0.485802&t=h&z=12&layer=c&cbll=39.311856,11.519322&panoid=1hltSSOoqv5H1dVKZWFkaA&cbp=13,117.95,,1,16.71'; As you can see, there's several location sets in the url. The cbll variable seems to be the right one in my case. This is what I came up with: preg_match("~&cbll=(-?\d+\.?\d*),(-?\d+\.?\d*)~", $url, $matches); The

问题 I was wondering how can I create preg_match for catching: id=4 4 being any number and how can I search for the above example in a string? If this is could be correct /^id=[0-9]/ , the reason why I'm asking is because I'm not really good with preg_match . 回答1: for 4 being any number, we must set the range for it: /^id\=[0-9]+/ \ escape the equal-sign, plus after the number means 1 or even more. 回答2: You should go with the the following: /id=(\d+)/g Explanations: id= - Literal id= (\d+) -

问题 I am trying to make a small program that searches within a timer (with this format 00d 00h 00m 00s) and returns the days into one variable, the hours into another, etc. This is some of my code: $time1 = "Left: 11d 21h 50m 06s <\/div>" preg_match_all("/ .*d/i", $time1, $timematch); // Day $time1day = $timematch[1]; // Saves to variable preg_match_all("/ .*h/i", $time1, $timematch); // Hour $time1hour = $timematch[1]; // Saves to variable preg_match_all("/ .*m/i", $time1, $timematch); // Minute
