why doesnt trim does what it sais it should do:P

[lajkonik86]

echo trim('[e-mail]\r\n');

gives me
[e-mail]\r\n
the manual makes me believe that it should remove the \r\n but somehow it doesnt:S

[bradgrafelman]

The manual entry for [man]trim/man says it will "strip whitespace". This means it will escape such characters as a carriage return (\r) or a line feed (\n).

You have neither one of those, however - you have 4 characters - two backslashes, one 'r', and one 'n'. Now, if you're talking about this:

$string = "this has new lines\r\n";

then trim() will strip the new lines at the end.

If you visit the manual page and read about what a [man]string[/man] is, you'll see that these 'escape sequences' are only parsed in double quoted strings.

Need double-quotes: "\r\n"

I never knew this thanks ! 🙂

So how could I fix this?

$emails = explode(',', $_POST['aan']);
$emails = fullclean($emails);
foreach ($emails as $key => $value) {
$emails[$key] = trim($value);
}

I don't see anything broken about it... not sure what you're asking.

Are you getting values you don't think you should be? Can you show us some sample output of $emails (perhaps using [man]var_dump/man for more debug info) as well as what you expected to get?

[lajkonik86]

Array ( [0] => [e-mail]\r\n\r\n )

Problem being that it doesnt strip the \r\n which is somehow related to the quotes.

[bradgrafelman]

If it's literally showing you \r\n\r\n, then those are the literal characters that were typed. var_dump() won't show those escape sequences if it finds a new line - it'll show you a new line.

What is the value of the magic_quotes_gpc directive? Perhaps this is escaping these sequences before your script touches the data?

My bad, I used print_r() instead of vardump

The input was in a textarea box with the following data
[e-mail](press enter twice after this)

[bradgrafelman]

Regardless of whether you used print_r() or var_dump(), if you're seeing "\r\n" then those are not line breaks. So...
