Remove 'New Line' (NL) from a STRING

[AndieB]

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!

 

Sincerely,

Andreas

trim

[phant0m]

str_replace("\", "", $string)

 

trim just removes whitespace at either end of a string

Really? So I guess the manual entry that I coincidentally supplied a link to must be lying.

lol crayon Violent is correct :)

 

function trim_value(&$value)

{

    $value = trim($value);

}

 

that would do job and its what i use!

[.josh]

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...

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);

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]

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.

[gizmola]

I agree about the ambiguity -- let's all get a beer! 

 

[.josh]

right. So if I do:

 

$string = "blah\n";

$string = trim($string);

 

that \n will be removed.
