(Output from a text area)

I want to pass this variable to a javascript function

I have write this in my php file

<?php echo "<script language=javascript>convert('$test');</script>"; ?>

but this makes an error "Unterminated st开发者_运维百科ring literal" How can i solve this issue ??

Try

$test = "This is a string\nIt has multiple lines\nthere are three total";

<script>convert(<?php echo json_encode($test); ?>);</script>

Try this:

$test = str_replace($test, "\n", "\\n");
