If you want "\n" to be converted to line breaks, you need to use double-quotes instead of single quotes.

i.e.

$foo = 'a\nb\nc\n';
echo $foo;
> a\nb\nc\n

$foo = "a\nb\nc\n";
echo $foo;
> a
> b
> c

In general: Use \n for line breaks.

In your case (only works of cites don't consist of two words, i.e. each word must be a city):

$city = str_replace(' ',"\n", $str); // generates 'London\nParis\nLisabona'

Or if possible build the string with \n instead of spaces from the beginning.

Update:

Escaped character sequences like \n are only processed in double quoted strings. They are taken literally in single quoted strings (with two exceptions). Read more in the documentation:

To specify a literal single quote, escape it with a backslash (\). To specify a literal backslash, double it (\\). All other instances of backslash will be treated as a literal backslash: this means that the other escape sequences you might be used to, such as \r or \n, will be output literally as specified rather than having any special meaning.

Thus, you have to declare your strings as

$cities = "London\nParis\nLisabona";

Further note:

Whenever possible avoid echoing HTML with PHP. It makes it more difficult to debug the HTML. Instead, embed the PHP into HTML like so:

<?php
    $cities = "London\nParis\nLisabona";
?>
<textarea><?php echo $cities; ?></textarea>

$city = str_replace(' ', "<br />", $city);

If you echo it in HTML.
