Delete newline in string.

[Anon]

Hello,

I want to delete the newline character at the end of a string. I tested the following, without success.

str_replace("\n", "", $string);
preg_replace("/\n/", "", $string);

I know that a newline exists, because I tested it with strrpos($string, "\n");

Any solution to this problem? I wonder that there is no specific function in PHP, to delete the newline at the end of a string, like chomp() in Perl.

P.S.: I use PHP 4.0.3pl1 with Debian Linux 2.2.18pre21

TIA

$string = str_replace("\n", "", $string);
works fine for me!

[You did prepend the new variable...

$string = str_replace("\n", "", $string);

...didn't you?]

If the data is coming in from a database or file, depending on your configuration, the newline might be escaped. Try:

$string = str_replace("\n", "", $string);

preg_replace("/\n/", "", $string);

replaces all newlines in the string.

try

preg_replace("/\n$/", "", $string);

or

preg_replace("/\r\n$/", "", $string);

Ok, correct me if I'm wrong, but doesn't str_replace do them all too?

Correct.

Hello,

thank you all for your answers. Now I know why str_replace did not worked. I overlooked that str_replace returns the edited string. I worked with the unedited copy of the string variable, that is part of the function parameters.

str_replace("\n", "", $string); // false
echo $string;

$string = str_replace("\n", "", $string); // true
echo $string;
