Question

I’m trying to get it once again.

I got a JS var which looks like this:

var test;

Now I write some JS with PHP:

<?php
    $phpvar = "a text with
    a linebreak";
    echo "<script type='text/javascript'>
        var test;
        test = '" . $phpvar . "';
    </script>";
?>

Now, if I run it, it outputs the source as follows:

<script type='text/javascript'>
var test;
test = 'a text with
a linebreak';
</script>

This gives me a JS exception:

ERROR: unterminated string literal

Somehow, JS seems not to recognize that there is a string on more than one line.

How can I realize this if, in the end, the string must have its linebreak again? (So, if all execution finishes, I must have the string including all linebreaks)

Thank you for your help 😉

Try this, if you use a \ at the end of a Javascript line, you can use multiple lines within a string.

<?php
    $phpvar = "a text with
    a linebreak";
    echo "<script type='text/javascript'>
        var test;
        test = '" . str_replace("\n", "\\\n",$phpvar) . "';
    </script>";
?>
