Description:
------------
Strings variables parsing, documented on http://ca2.php.net/manual/en/language.types.string.php#language.types.string.parsing
, has a complex form that puts an expression inside braces. This allows many kinds of expressions, so the page gives several examples, but one isn't an example of that:

echo "This is ${great}";

I don't know where that example belongs.

It's already there:

echo "This is {$great}";
echo "This is ${great}";

Huh, what is already where?

Aha. I see what you mean. The documentation says "Since { can not be escaped, this syntax will only be recognised when the $ immediately follows the {."

This makes no mention of "{ immediately following the $".

In fact, that looks SO wrong that I'm surprised it isn't a parse error.

I don't know how to explain the usage.

${great} is a variation of the simple syntax ("Enclose the variable name in curly braces to explicitly specify the end of the name."), and so the example should be moved up one section.

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.
