Variable assignment: Curly braces inside question marks?

[peterhuynh]

I'm looking at this:

$message = “{$nonce}{$token}{$path}0.1buy965.45”; 

Can someone tell me what the syntax means.

 

Thanks.

Take a look at this page of the manual: http://php.net/manual/en/language.types.string.php#language.types.string.parsing

 

Specifically, look at the complex method.

Agree with Psycho.  By the way, each does the same thing:

$message = “{$nonce}{$token}{$path}0.1buy965.45”; 
$message = $nonce.$token.$path."0.1buy965.45”; 
$message = $nonce.$token.$path.'0.1buy965.45';

or

$message = "$nonce$token{$path}0.1buy965.45"; 

$path requires the {..} to prevent it being interpreted as $path0 which would be a valid variable name
