Accessing superglobal elements

[Michaelp]

Hello!

I see that I can access a superglobal element using the index this
way:

print("<p>$_GET[surname]</p>"); //(element index without any
delimiters within a double-quotation-mark-delimited string)

But not this way:

print("<p>$_GET['surname']</p>"); //(apostroph-delimited element index
within a double-quotation-mark-delimited string)

The latter gives me an error message:
Parse error: syntax error, unexpected T_ENCAPSED_AND_ WHITESPACE,
expecting T_STRING or T_VARIABLE or T_NUM_STRING
Why is that? (I cant understand why PHP gets confused by that)

Is this configurable?

Thanks
Michael

Actually, the first should give you a notice, also. But you evidently
have notices disabled.

And no, you can't configure it. Just use curly braces, i.e.

print("<p>{$_GE T['surname']}</p>");

Posted the links only days ago, but here you go:
http://nl2.php.net/manual/en/languag...string.parsing

So, use:
"<p>{$_GET['surname']}</p>"

(Well, actually, don't, unless you're sure you've checked the GET variable
for XSS attacks.

Rik is right--the curly's {} will do what you want to do, and you
should clean your variables from the user. PHP has some built-in
methods, but Cal Henderson has an even better way to do this:
