AndieB Posted June 30, 2009 Share Posted June 30, 2009 Hi, if I fetched some data into a string from a database, how do I remove the NL (new line) in the string?? Could be a case where I also get a POST from a FORM treated by PHP. Thankful for any kind of help!

phant0m Posted June 30, 2009 Share Posted June 30, 2009 str_replace("\", "", $string) trim just removes whitespace at either end of a string Link to comment https://forums.phpfreaks.com/topic/164288-remove-new-line-nl-from-a-string/#findComment-866641 Share on other sites More sharing options...
.josh Posted June 30, 2009 Share Posted June 30, 2009 Really? So I guess the manual entry that I coincidentally supplied a link to must be lying.

runnerjp Posted June 30, 2009 Share Posted June 30, 2009 lol crayon Violent is correct :) function trim_value(&$value) { $value = trim($value); } that would do job and its what i use!

.josh Posted June 30, 2009 Share Posted June 30, 2009 I hope that function is being used with something like array_walk because if not, I don't really see why you can't just use trim() directly...

gizmola Posted June 30, 2009 Share Posted June 30, 2009 Really? So I guess the manual entry that I coincidentally supplied a link to must be lying. Guys? trim only removes whitespace characters from beginning and end of strings. Phant0m is correct. $str = "This is line 1.\nThis is line 2.\nThis is line3.\n"; $str = trim($str); echo nl2br($str); Link to comment https://forums.phpfreaks.com/topic/164288-remove-new-line-nl-from-a-string/#findComment-866692 Share on other sites More sharing options...
.josh Posted June 30, 2009 Share Posted June 30, 2009 from the manual: Description string trim ( string $str [, string $charlist ] ) This function returns a string with whitespace stripped from the beginning and end of str . Without the second parameter, trim() will strip these characters: * " " (ASCII 32 (0x20)), an ordinary space. * "\t" (ASCII 9 (0x09)), a tab. * "\n" (ASCII 10 (0x0A)), a new line (line feed). * "\r" (ASCII 13 (0x0D)), a carriage return. * "\0" (ASCII 0 (0x00)), the NUL-byte. * "\x0B" (ASCII 11 (0x0B)), a vertical tab. I will concede that that doesn't remove new lines from in the middle of the string...OP is somewhat ambiguous on that count though...

gizmola Posted June 30, 2009 Share Posted June 30, 2009 You're misreading the manual CV. What it means is that it will do the trim action on all those characters, unless you specify the 2nd parameter, which will then act only on the characters you specified.

.josh Posted June 30, 2009 Share Posted June 30, 2009 right. So if I do: $string = "blah\n"; $string = trim($string); that \n will be removed. Link to comment https://forums.phpfreaks.com/topic/164288-remove-new-line-nl-from-a-string/#findComment-866710 Share on other sites More sharing options...
