Re: String in php and js script

It's generally considered best practices to wrap HTML elements in
double quotes.
So, your onclick event handler should look like this:

onclick="js_tes t('<?php echo $string; ?>');"

(Note that it is also considered good form to use <?php ... ?to
denote PHP code at all times.)

Depending on the contents of $string, you might also want to use the
addslashes() function, like so...
onclick="js_tes t('<?php echo addslashes($str ing); ?>');"

Hope this helps.

Attributes. And both single and double quotes are perfectly valid. In
this case it might make a difference because of the JS, but usually it
doesn't matter.

XHTML allows you to use both single or double, but it's best to use
the double quotes since it's what most people expect.

Also, addslashes is perfect for this problem. Sounds like you'll need
to sanitize the string with htmlspecialchar s.

My 2 cents,

Who expects that?

Apparantly, some very, very bad parsers(1). And as XHTML is rendered as
tag soup most of the time anyway, and it's perfectly legal to use either
one, just take your pick. I just prefer double quotes because that's what
I'm used to, no other greater good in mind then ease of code :).

That's perfectly OK. I also usually use double quotes, but often enough
I use single quotes, if it makes my PHP code more readable:

print "<img src='$someVar' alt='...'>\n";

vs.

print "<img src=\"$someVar\ " alt=\"...\">\n" ;

or

print '<img src="'.$someVar .'" alt="...">'."\n ";

I definitely prefer the first one. Every browser accepts it and for the
website user it doesn't matter at all.
