Line breaks in if statements

[gerkintrigg]

Hello
How do i check if a variable has a line break in an if statement? I've broken a database field (address) into variables for each line and i noticed that if I left the line blank (with only a line break in it) it acts all goofy...

Can anyone help?
I tried this:[code]<?php
if (($_REQUEST['e']==y)&&(($city=='')||(nl2br($city)=='<br />'))){
echo 'bgcolor="#FF9999"';
}
else{
echo'bgcolor="#FFFFFF"';
}
?>[/code]

try
[code]
<?php
if (($_REQUEST['e'] == "y") && (($city == null) || ( nl2br( $city ) == "<br />"))){
echo "bgcolor=\"#FF9999\"";
} else {
echo "bgcolor=\"#FFFFFF\"";
}
?>
