How to store HTML code (with " ", ' ') inside a variable in php script?

Hello to everyone,

Assuming i have this simple script :

<?PHP

//Opening tag ='
$html_header='
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
'; // Closing tag ='

echo $html_header;

?>

If the opening & closing tags are both ' then it works fine, but if the
html script itself contains a ' then i need some way to escape it, no ?

How should i do it if i had something like <HEAD><TITLE='PHP foo'></HEAD>?

Thank you. :)

[nit-picking]
Tags and attributes should be lower case
Attribute values should be in double quotes no single.
<title=...> is not valid html; <title>PHP foo</title> is
[/nit-picking]

Use \'

Yes. You should escape it with \ or just use the very versatile
heredoc syntax.

Option One:

$head = '<HEAD><TITLE=\'PHP foo\'></HEAD>';

Option Two:

$head = "<HEAD><TITLE='PHP foo'></HEAD>";

Option Three:

$head = <<<ENDOFHEAD
<HEAD><TITLE='PHP foo'></HEAD>
ENDOFHEAD;

Option Four:

$head = '<HEAD><TITLE="PHP foo"></HEAD>';

Although of course this isn't valid HTML as the title tag works like this:

<title>PHP Foo</title>

and the tags and attributes should be in lower case because you have defined
XHTML Script as your document type.

You *can* use single quotes. I can't find this referenced anywhere, but I
just made a test document in both 1.0 Strict and 1.1 and they both
validated when using single quotes for attribute values.

This is not required, and the examples in the HTML specification have the
element names in upper case.

HTML4.0.1, sec 1.2.1 (Document Conventions, Elements and Attributes):
http://www.w3.org/TR/html4/about.html#h-1.2.1

"Element names are written in uppercase letters (e.g., BODY). Attribute names
are written in lowercase letters (e.g., lang, onsubmit). Recall that in HTML,
element and attribute names are case-insensitive; the convention is meant to
encourage readability."

HTML4.0.1, sec 3.2.1:
http://www.w3.org/TR/html4/intro/sgmltut.html#h-3.2.1

"Element names are always case-insensitive."

Single quotes are perfectly acceptable; they're explicitly allowed in the HTML
specification, via the SGML specification:

HTML4.0.1, sec 3.2.2:
http://www.w3.org/TR/html4/intro/sgmltut.html#h-3.2.2

"By default, SGML requires that all attribute values be delimited using either
double quotation marks (ASCII decimal 34) or single quotation marks (ASCII
decimal 39)."

It's defined back in the XML spec; see the two alternatives, one for double
quotes and the other for single quotes:

Well actually in his example he was using XHTML Strict as the document type
so tags and attributes *must* be in lower case.

Yeah, I cancelled the post after seeing it was XHTML (despite the subject
saying HTML) but it looks like it was too late and the message got out.

I knew I'd seen it somewhere the other day. Although my eyes normally glaze
over when I try to read DTDs...
