newline

问题 I'm using this but it's replacing single occurances of a new line with <br/><br/> function nl2br2($string){ $string = preg_replace('/(\r\n){2,}/', '<br/><br/>', $string); //$string = preg_replace('/[\r\n]/', '<br/>', $string); return $string; } It happens with the first pattern. 回答1: Well, I suspect that perhaps your input may not be '/r/n' but only '\n'. In this case you should make your regex to detect that like this: '/(\r?\n){2,}/'. So your code might be: function nl2br2($string){ $string

问题 I am sending an email via CodeIgniter's email->send(). I have come across an anomaly that I cannot figure out. "\r\n" is not working in a certain section of the email. However if I switch "\r\n" to "\r\n\r\n" it works. By works I mean, it adds the 2 line breaks expected. The problem area is at the bottom. $order = $this->ordersclass->getOrder( $order_id ); $quantity = $order['no_codes']; $client = $this->clientclass->getClient( $order['client_id'] ); $multi_d = $this->session->userdata('multi

问题 I'm using two distros which use bash v4.3.48 and v4.4.7. read VAR1 VAR2 <<< $(echo 0 ; echo 1) echo $VAR2 For bash v4.3.48, the result of commands above is $VAR2 has value 1. But, with bash 4.4.7, $VAR2 is null. To get the same result, in 4.4.7, I must modify the script: read VAR1 VAR2 <<< $(echo -n $(echo 0 ; echo 1) ) I don't know my (previous) script was wrong or there're changes in the newer bash. 回答1: It looks like the behavior when expanding <<< $( ) has changed slightly. Normally, when

问题 I have an issue where amounts of text (in my case a ToS) is not rendering properly onto the screen (this occurs when the string makes the text field larger than a height of 8000). I've read the solution to the problem is to split the ToS into multiple text tags. How could I go about splitting the string at every new line and programatically generating a text tag for it? for example: "paragraph1... paragraph2...." into: <Text>paragraph1...</Text> <Text>paragraph1...</Text> 回答1: This is

问题 I always have my multi-line variables defined like this: var query = "\ SELECT \ this AS that \ CASE something \ FROM table \ WHERE something \ " But in Eclipse , in the default JavaScript Editor in Eclipse 3.8.0 Web Tools Platform (WTP), everytime I press return, or paste a couple of lines, Eclipse will add quotes like this: var query = "\ SELECT \ this AS that \ CASE something \ FROM table \" + " JOIN pasted.line1 \" + " JOIN pasted.line2 \" + " JOIN pasted.line3 \" + " JOIN pasted.line4 \"

问题 I'm building a script to get all the triggers in the document, but I want to include newlines. I'm copying and pasting this into excel in order to then quickly generate some mandated documentation, but all the contents from the text column end up being generated without newlines. The line I'm currently using, which produces truncation in results to file is: SELECT OBJECT_DEFINITION(sys.objects.object_id) FROM sys.objects WHERE type = 'TR' 回答1: Tools->Options->Query Results->Results to file No

问题 How to replace multiple line breaks with one new line charatcer in oracle server using REGEXP_REPLACE. 回答1: I think this is what you are after. Dealing with carriage returns can get tricky depending if you are on Windows or UNIX but you'll get the idea. This was run in Toad, which uses a regular expression which looks for occurrences of two or more newline characters in a row and replaces them with one newline. 来源： https://stackoverflow.com/questions/32518929/replace-multiple-line-breaks-with

问题 I know $ is used to check if a line end follows in a Java regular expression. For the following codes: String test_domain = "http://www.google.com/path\nline2\nline3"; test_domain = test_domain.replaceFirst("(\\.[^:/]+).*$?", "$1"); System.out.println(test_domain); The output is: http://www.google.com line2 line3 I assume that the pattern (\\.[^:/]+).*$? matches the first line, which is http://www.google.com/path , and the $1 is http://www.google.com . The ? makes a reluctant match (so

问题 Problem : My Django app is introducing a CR before each CRLF when writing to a file a string which has been read in via render_to_string. In my template files, I used CRLFs, and the Django processing app writes a file which adds a CR before each CRLF. See below for code details. However : this only happens with my app which is on my clients' Windows Server 12R2 VM which is located in France. My physical Windows 10 laptop, my ubuntu instances, and my AWS Windows Server 12 instance (which I use

问题 I'm developing software under Linux which will be compiled using a Windows-only compiler. I want git to store my files with CR-LF line endings in the repository on Linux to be able to package the sources without changing them to Windows style. My .gitattributes looks like: *.cpp eol=crlf *.h eol=crlf I also already tried core.eol = crlf . But git is still using LF line endings when I do checkouts and commits on Linux. Is there any way to tell git using CR-LF on Linux? 回答1: Does the windows
