问题 I have spent over 4 hours trying to find a regex patter to my php code without luck. I have a string with html code. It has lot of urls formats like: site*com http://site*com http://www*site*com http://site*com/some.php http://site*om/some.php?var1=1 http://site*com/some.php?var1=1&var2=2 etc. I have the following php code working in part: preg_match_all('/\b(?:(?:https?|ftp|file):\/\/|www\.|ftp\.)[-A-Z0-9+&@#\/%=~_|$?!:,.]*[A-Z0-9+&@#\/%=~_|$]/i', $content, $result, PREG_PATTERN_ORDER); The

问题 I need to print all matches using preg_match_all. $search = preg_match_all($pattern, $string, $matches); foreach ($matches as $match) { echo $match[0]; echo $match[1]; echo $match[...]; } The problem is I don't know how many matches there in my string, and even if I knew and if it was 1000 that would be pretty dumb to type all those $match[] 's. 回答1: The $match[0] , $match[1] , etc., items are not the individual matches, they're the "captures".

问题 I am trying to load a remote website and get all numbers that are inside of parentheses. But what ends up happening is it only matches the last value. Is my regex wrong?

问题 $text = 'Lorem Ipsum'; $re = '/(?<AA>Any)|(?<BB>Lorem)/ui'; $nMatches = preg_match_all($re, $text, $aMatches); $aMatches will contain the following: Array ( [0] => Array ( [0] => Lorem ) [AA] => Array ( // do not include to result matches array [0] => // because have not match for this part ) [1] => Array ( [0] => ) [BB] => Array ( [0] => Lorem ) [2] => Array ( [0] => Lorem ) ) Question: Is it possible to return the array without nodes for named parts that have no matches?

问题 I am trying to validate a bunch of text and check if there are any emails in it... so i use the following code: if (preg_match_all("/^([a-zA-Z0-9_.-])+@([a-zA-Z0-9_.-])+\\.([a-zA-Z])+([a-zA-Z])+/", $str, $matches)){ } this will work for TEXT_A in Page1 but when i go in Page2 and try to check again on TEXT_A it will kill the page with "Problem loading page" error... if i remove this check the page will load fine... i dont get why this is happening... edit:im using CodeIgniter 回答1: I see a

问题 I have a string for example "lorem 110 ipusm" and I want to get the 110 I already tried this: preg_match_all("/[0-9]/", $string, $ret); but this is returning this: Array ( [0] => 1 [1] => 1 [2] => 0 ) I want something like this Array ( [0] => 110 ) 回答1: To catch any floating point number use: preg_match_all("/[+-]?\d+[\d\.Ee+]*/", $string, $matches); for example: <? $string = 'ill -1.1E+10 ipsum +1,200.00 asdf 3.14159, asdf'; preg_match_all("/[+-]?\d+[\d\.Ee+]*/", $string, $matches); var_dump

问题 So I have to use php 7 and I have the following regex which works just fine in 5.5 and 5.6. ([\\'\\\"].*[\\'\\\"])([\\s]*[\\s]*=>[\\s]*[\\s])(\\[([^\\[\\]]|(?R))*[\\s]*[\\s]\\])/m when I run this in any version of 5 with preg_match_all I get the correct result.
