This is fine and works perfectly (you can drop the quotes around the key
name when inside double quotes):

$localvariable = 'white background';
//$_POST['Name'] previously set to 'John'
$bigstring = "normal text with $localvariable for $_POST[Name] to read.";

outputs: normal text with white background for John to read.

and...

$localvariable = 'white background';
//$_POST['Name'] previously set to 'John'
$bigstring = "normal text with $localvariable for '$_POST[Name]' to read.";

outputs: normal text with white background for 'John' to read.
