![]() ![]() ![]() In the Value field hit Enter, you should see the field growing vertical. It works twice as fast in the average case and probably a lot faster when there are many short lines. Initialize a variable of type string, e.g. You can remove line breaks from blocks of text but preserve paragraph breaks with this tool. Verdict: str_replace wins in generalĪnd if you can afford to have spaces instead of, use strtr with characters. Tested by PaulDixon and verified by myself. Ive been working with phrases the past couple of days and the only problem I seem to be facing is stripping new lines in the html before printing it. Decide yourself if you want to remove non-breaking space chr(160) as it can cause problems. To remove newline character in PHP, follow the steps below:- U can try the code below str there is new linenin this stringn x pregreplace(/nr/. Note: The usual whitespace is chr(32) so it stays in the result. If you dont specify a specific string, the TRIM() function removes spaces only. Also, if you're looking for performance this might not be it, but for a quick tool that does the job in any case, this should be useful. If you want to keep all whitespace characters \t, and \r, then remove chr(9), chr(10) and chr(13) from this list. The removedstr is the string that you want to remove. If something doesn't fit your case, just remove it. With long strings and many replacements, the difference will grow because character substitutions are linear by nature. The following is a drop-in function that implements everything the above Wiki page considers 'new line' at the time of this answer. So it's not exactly what the OP described, but it's clearly the fastest. It's even faster, and it makes sense because when you get rid of line breaks, you probably don't want to concatenate the word at the end of one line with the first word of the next. The last one is a dirty trick: it replaces characters with characters, that is, newlines with spaces. ![]() They deal with arrays, and they do exactly what we told them - remove the newlines, replacing them with nothing. On the other hand, in line 2-3, str_replace and strtr are doing almost the same job and they perform quite differently. Nor will they appear when you are looking at the text column in your database. They will not show up when you print the text out onto your web page. It's simply not fair to expect them to win. Firstly, you need to realize that newlines and carriage return characters \r are usually invisible. They do a different job and PHP has no prepared regex, so it's parsing the expression every single time. The preg_replace solution is noticeably slower, but that's okay. (Note that it's a realtime test and server loads may change, so you'll probably get different figures.) Results 251.84 ticks using preg_replace("/+/"," ",$text) Ĩ1.04 ticks using strtr($text,) ġ1.65 ticks using str_replace($text,) str_replace, and strtr goes twice because it has a single character and an array-to-array mode. I compared the four most promising methods, preg_replace vs. You have to be cautious of double line breaks, which would cause double spaces. Things have changed since I last answered this question, so here's a little test I created. ![]()
