How to make php output // in html? (without comment out)

Netthandel

I am still in the process of making my site better, and I want an:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">

in the above the <html> and <head> in the HTML doc.

This site is generated by php/ MySQL, and I have located the:

function draw_head_tag(&$db)
	{
		echo "<html>\n<head>\n";

HOW do I put in the

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">

WITHOUT making the // comment out the code?

Thanks for answer!

Am I right in assuming you're putting that line directly in the PHP code for the // to comment out the line?

If so, it needs to be either outside the PHP tags, or echo'd/printed. Namely:

<?php
echo '<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">';
?>

The single quotes around it will mean "take this literally" (or that’s my interpretation of it anyway!) basically means it won't execute anything in-between, such as the double quotes in the HTML code which would otherwise end the line early.. (with error)

Not sure what it is you are trying to do but here you go

echo "<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.0 Transitional//EN\">\n";

You do know that to view such stuff as a tag you will have to view the source, are are you wantinng to print the actual tag to the screen as an example of codeing something?

Hi!
Thanks a lot!
This helped me out Benbox! :-)

assuming you're putting that line directly in the PHP code

Yes! - Your somment did the trick.

Also thanks to you Houdini!
I guess it's the same if I use ' or " ?

AND: Yes, it's only to be put in hidden code (as you see when clicking "view source" in the browser) - helping to indicate the standard

This forum is awsome (at least for a newbie as me).

There are many ways you can do it, double and single quotes have benefits in their own situations..

a couple of examples (which all do the same thing)..

<a href="link.htm"><?php echo $linkText; ?></a>

<?php
echo "<a href=\"link.htm\">$linkText</a>";
?>

<?php
echo '<a href="link.htm">' . $linkText . '</a>';
?>

Also remember that the html will also work with single quotes instead of double...

<?php
echo "<a href='link.htm'>$linkText</a>";
?>

Or you can use Heredoc quoting to specify a specific sequence of characters to act like a "custom quote":

function draw_head_tag(&$db)
{
// Assuming "EOH" never appears on a line by itself in the text being quoted
echo <<<EOH
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html>
<head>
EOH;

Or, since it's just being outputted and not processed, just don't put the line into the PHP code in the first place...

function draw_head_tag(&$db)
{
?>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html>
<head>
<?php

PS. the appropriate doctype is

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
   "http://www.w3.org/TR/html4/loose.dtd">

assuming that the page really is HTML4 compliant.
