line-breaks

问题 I have a php parser that split a given string by line-breaks, doing something like this: $lines = explode(PHP_EOL,$content); The parser works fine when working on server side. However, when I pass the content via post by ajax (using jquery's $.post method) the problem arises: line breaks are not recogniezed. So after almost an hour of tests and head-aches I decided to changed PHP_EOL by "\n" and it worked: $lines = explode("\n",$content); Now it works! Damn it I lost so much time! Could

问题 I am currently trying to learn how to use regular expressions so please bear with my simple question. For example, say I have an input file containing a bunch of links separated by a newline: www.foo.com/Archives/monkeys.htm Description of Monkey's website. www.foo.com/Archives/pigs.txt Description of Pig's website. www.foo.com/Archives/kitty.txt Description of Kitty's website. www.foo.com/Archives/apple.htm Description of Apple's website. If I wanted to get one website along with its

问题 What's the difference between \n and \r (I know it has something to do with OS), and what's the best way to echo a line break that will work cross platform? EDIT: In response to Jarod, I'll be using ths to echo a line break in a .txt log file, though I'm sure I'll be using it in the future for things such as echoing HTML makup onto a page. 回答1: \n is a Linux/Unix line break. \r is a classic Mac OS (non-OS X) line break. Mac OS X uses the above unix \n . \r\n is a Windows line break. I usually

问题 So here is what I have: <path class="..." onmousemove="show_tooltip(event,'very long text \\\n I would like to linebreak')" onmouseout="hide_tooltip()" d="..."/> <rect class="tooltip_bg" id="tooltip_bg" ... /> <text class="tooltip" id="tooltip" ...>Tooltip</text> <script> <![CDATA[ function show_tooltip(e,text) { var tt = document.getElementById('tooltip'); var bg = document.getElementById('tooltip_bg'); // set position ... tt.textContent=text; bg.setAttribute('width',tt.getBBox().width+10);

问题 var i; for(i=10; i>=0; i= i-1){ var s; for(s=0; s<i; s = s+1){ document.write("*"); } //i want this to print a new line /document.write(?); } I am printing a pyramid of stars, I can't get the new line to print. 回答1: Use the \n for a newline character. document.write("\n"); You can also have more than one: document.write("\n\n\n"); // 3 new lines! My oh my! However, if this is rendering to HTML, you will want to use the HTML tag for a newline: document.write("<br>"); The string Hello\n\nTest

问题 Trying to simply replace some new lines. Have tried 3 different ways and I get no change: $description = preg_replace('/\r?\n|\r/','<br/>', $description); $description = str_replace(array("\r\n","\r","\n"),"<br/>", $description); $description = nl2br($description); These should all work but I still get the newlines. They are double: "\r\r". That shouldn't make any of these fail right? 回答1: There is already nl2br() function that replaces inserts <br> tags before new line characters: Example

问题 I want to use line breaks in my website description meta tag. How do I do it, because if I see the source code it will still show <br/> only. Something like this I use in my code: <meta name="description" content="<?php echo $gotAlias ?><br/> abc: <?php echo $got_overallrating ?>.<br/> <a href='www.abc.com'>Visit www.abc.com</a> "> 回答1: Try "\n" instead of <br /> , e.g. <?php echo "first line\nsecond line"; ?> ; 回答2: For use in AddThis meta content tagging, the \n is ignored. So it doesn't

问题 I tried to send an e-mail with a prepared subject, receiver and body using Qt. The mail shall open in the system default mail client. I am testing on Linux with KMail and Qt 5.5. This is the code I intended to use: QDesktopServices::openUrl(QUrl("mailto:?to=test@test.com&subject=Test&body=line1%0D%0Aline2", QUrl::TolerantMode)); The mail window opens, subject and receiver are ok. Unfortunately the line breaks in the body do not work. I also tried <br>, \n, \r\n but none of these worked. I

问题 As in the picture, I would force a line break when I have one word after the dot , for a aesthetic issue, but especially as a matter of good reading. It's possible? http://i.stack.imgur.com/EkcuR.jpg 回答1: This works too (*same situation - you don't want a text break after a single word. My solution to that is to select the first two words, wrap them with a span with a class and don't let that text break): <style> section{ width:500px; float:left; font:14px; } .first-two-words2 { font-style

问题 I'am using EncodeString in Delphi 7 to encode strings which load from a source textfile. In the source textfile, every line is one record. Now, I want to use the function EncodeString which is Base64 function to encode every line string and write to a new target textfile. My purpose is one line strings in source textfile should encode to one line encryption strings in target textfile. But every line encode to 3 lines encryption strings. There are several line-breaks made to 3 lines. How can I
