Windows uses two characters for definining newlines, namely ASCII 13
(carriage return, "\r") and ASCII 10 (line feed, "\n") aka CRLF. So if
you have a string with CRLF's, trim() won't recognize them as being one
newline. To solve this you can use str_replace() to replace the CRLF's
with with a space or something.
<?php
// string with bunch of CRLF's
$my_string = "Liquid\r\nTension Experiment\r\n\r\n\r\n";
// replace CRLF's with spaces
$my_wonderful_string = str_replace("\r\n", " ", $my_string);
// would result in "Liquid Tension Experiment "
// or just delete the CRLF's (by replacing them with nothing)
$my_wonderful_string = str_replace("\r\n", "", $my_string);
// would result in "LiquidTension Experiment"
?>
