I had a problem where I was defining javascript variables from php variables, and the php variables had multiple lines.

So, a function like this:
function SomeFunction() {
var variable = "<?php echo $variable; ?>";
}


was creating this:
function SomeFunction() {
var variable = "The first row.
The second row.
The third row
";
}

The fix was to replace all the ‘\n’ with ‘\\n’, so the literal string ‘\n’ is output instead of an actual line break.

Like so:
var variable = "<?php echo str_replace('\n', '\\n', $variable); ?>
