I am using this preg_match string preg_match('/Trident/7.0; rv:11.0/',$_SERVER["HTTP_USER_AGENT"] to detect IE11 so I can enable tablet mode for it. However it returns "unknown delimiter 7". How can I do this without PHP complaining at me? Is this really a regular expression or just a literal string? If it's just a string, you can use the strpos function instead. if (strpos($_SERVER['HTTP_USER_AGENT'], 'Trident/7.0; rv:11.0') !== false) { // your code } If it's a regular expression, you must escape special characters like / and . EDIT: You can see in the comments of this answer that the code

How would I use PHP to extract everything in between [startstring] and [endstring] from this string: [startstring]hello = guys[endstring] hello guys [startstring]jerk = you[endstring] welcome to the universe I'd like to find all the matches of [startstring] and [endstring] , and echo the text inside. Kinda like a delimiter. And I would like all the matches echoed to be seperated by a space. How would I go about accomplishing this? Would this require regex ? Could you provide a sample? Thanks so much! :) preg_match_all('/\[startstring\](.*?)\[endstring\]/s', $input, $matches); echo implode(' ',

From a string that contains a lot of HTMl, how can I extract all the text from <h1><h2>etc tags into a new variable. Possibly using preg_match_all and sending the matches to a single comma delimited variable. Thanks guys. Scott Saunders If you actually want to use regular expressions, I think that: preg_match_all('/<h[0-6]>([^</h[0-6]>*)</h/i', $string, $matches); should work as long as your header tags are not nested. As others have said, if you're not in control of the HTML, regular expressions are not a great way to do this. First you need to clean up the HTML ($html_str in the example)

how to remove multiple slashes in URI with 'PREG' or 'HTACCESS' site.com/edition/new/// -> site.com/edition/new/ site.com/edition///new/ -> site.com/edition/new/ thanks using the plus symbol + in regex means the occurrence of one or more of the previous character. So we can add it in a preg_replace to replace the occurrence of one or more / by just one of them $url = "site.com/edition/new///"; $newUrl = preg_replace('/(\/+)/','/',$url); // now it should be replace with the correct single forward slash echo $newUrl $url = 'http://www.abc.com/def/git//ss'; $url = preg_replace('/([^:])(\/{2,})/',

I am trying to make a date regex validator. The issue I'm having is that I'm using an input field with "date" type, which works like a charm in Chrome; it opens a calendar-like in Chrome, but in the rest it does nothing, so I decided to go for a manual input of the date for the rest. This is my error throwing message (I'm looking for YYYY-MM-DD format): $date_regex ='#^(19|20)\d\d[\- /.](0[1-9]|1[012])[\- /.](0[1-9]|[12][0-9]|3[01])$#'; $hiredate = $_POST['hiredate']; if (!preg_match($date_regex, $hiredate)){ $errors[] = 'Your hire date entry does not match the YYYY-MM-DD required format.'; }

I need some help with php regex, I want to "split" email address "johndoe@example.com" to "johndoe" and "@example.com" Until now I have this: preg_match('/<?([^<]+?)@/', 'johndoe@example.com', $matches); And I get Array ( [0] => johndoe@ [1] => johndoe) So how I need to change regex? $parts = explode('@', "johndoe@example.com"); $user = $parts[0]; // Stick the @ back onto the domain since it was chopped off. $domain = "@" . $parts[1]; Some of the previous answers are wrong, as a valid email address can, in fact, include more than a single @ symbol by containing it within dot delimited, quoted
