问题 I have stumbled upon a really odd bug with PHP's preg_replace function and some regex patterns. What I'm trying to do is replace custom tags delimited by brackets and convert them to HTML. The regex has to account for custom "fill" tags that will stay with the outputted HTML so that it can be replaced on-the-fly when the page loads (replacing with a site-name for instance). Each regex pattern will work by itself, but for some reason, some of them will exit the function early if preceded by

问题 I have a text file that has the literal string \r\n in it. I want to replace this with an actual line break (\n). I know that the regex /\\r\\n/ should match it (I have tested it in Reggy), but I cannot get it to work in PHP. I have tried the following variations: preg_replace("/\\\\r\\\\n/", "\n", $line); preg_replace("/\\\\[r]\\\\[n]/", "\n", $line); preg_replace("/[\\\\][r][\\\\][n]/", "\n", $line); preg_replace("/[\\\\]r[\\\\]n/", "\n", $line); If I just try to replace the backslash, it

问题 How can I strip off certain html tags and allow some of them?

问题 I have a problem to replace some serial number such as [30] [31] [32]... to [31] [32] [33]... in MS word when I insert a new references in the middle of article. I have not found a solution way in GUI so I try to use VBA to do that replacement. I find a similar problem in stack overflow: MS Word Macro to increment all numbers in word document However, this way is a bit inconvenient because it have to generate some replacement array in other place. Can I make that replacement with regex and

问题 I want to convert a set of Unicode code points in string format to actual characters and/or HTML entities (either result is fine). For example, if I have the following string assignment: $str = '\u304a\u306f\u3088\u3046'; I want to use the preg_replace function to convert those Unicode code points to actual characters and/or HTML entities. As per other Stack Overflow posts I saw for similar issues, I first attempted the following: $str = '\u304a\u306f\u3088\u3046'; $str2 = preg_replace('/\u[0

问题 I am attempting to remove apostrophes from text and it isn't really working. It's got to be something small. $text = preg_replace('/\'/', '', $text); That's what I am using right now to remove it. What am I doing wrong? There is a series of these to remove special characters to turn them into urls and store them in my database. However, a recent batch appeared with a ' where the ' was. Any help is greatly appreciated. Thank you in advance. 回答1: Have a go using str_replace(), it's quicker than

问题 I know other people have submitted questions around this error, however I can't see how this regex or the subject string could be any simpler. To me this is a bug, but before submitting it to PHP I thought I'd make sure and get help to see if this can be simpler. Here's a small test script showing 2 strings; one with 1024 x's and one with 1023: // 1024 x's $str = '

问题 I have the following code: this code finds all html tags in a string and replaces them with [[0]], [[1]] ,[[2]] and so on.(at least that is intented but not workinng); $str = "some text <a href='/review/'>review</a> here <a class='abc' href='/about/'>link2</a> hahaha"; preg_match_all("|<[^>]+>(.*)</[^>]+>|U",$str, $out, PREG_OFFSET_CAPTURE); $count = 0; foreach($out[0] as $result) { $temp=preg_quote($result[0],'/'); $temp ="/".$temp."/"; preg_replace($temp, "[[".$count."]]", $str,1); $count++
