True however K.I.S.S would say , if you can use it like
echo “This is a statement {$Blah}.”;
echo “This is also a statement {$objBlah->BlahString}.”;
echo “This is also a statement {$tBlah[‘BlahKey’]}.”;
You should do it so you are always using the same expected format, cleaner for
readability and training other people to understand how you code.
This is my personal thoughts on it, everyone has their own prefs.

There is always sprint type functions also.

You need to use double quotes (or HEREDOC) if you want PHP to replace $variable
with its value in the string:
$message="
<b> There is a text $variable trial. </b> ";
or
$message = <<<MESSAGE
<b> There is a text $variable trial. </b> MESSAGE;

The {} only become really useful when you're trying to reference arrays within
a string:
$var = array('great', 'boring');
$text = "this is {$var[0]}.";
Without the curly braces, PHP wouldn't be able to figure out whether you wanted
the end string to be 'This is great.' or 'This is [0].' despite the variable
itself clearly being an array.
Thanks,
