Question

A user enters URLs in a box like this:

1. google.net
2. google.com

I then try to validate / check the URLs, so:

function check_input($data) {
    $data = trim($data);
    $data = mysql_real_escape_string($data);
    return $data;
}

After validation:

$flr_array = explode("\n", $flr_post);

So, I can validate each URL. But mysql_real_escape_string finds spaces between URLs and adds:

<--print_r information-->
google.net\r\ngoogle.com

My URLs should and look like these:

1. google.net
2. google.com

How do I remove \r, because it breaks everything else?
Is there a better way to validate URLs?

Tried with str_replace, but no luck.

Thats where difference between single and double quotes comes into picture:

$flr_array = explode('\r\n', $flr_post);
