Question

I’ve seen this in a couple of scripts, but got no clue what it means. As already seen in the title of this thread, the syntax is like this: {$variable1}{$variable2}. Is it equivalent to: $variable1.$variable2 ?

Thanks for help!

Answer 1

Simple answer is yes, it is the same. A variable contained within those brackets outputs that variable.
Note that you can’t do anything like this, sadly:

$a = "hello: {$a+1}";

or

$b = "world: {someFunction($a)}";

It’s just a quick way of outputting variables so things don’t get all complicated.
Try looking at:

echo "hello mr {$name}!";

vs

echo "hello mr ".$name."!";

The first is much clearer.

It is much better to put variables in braces because it looks nicer, is clearer to read and also lets you have letters directly after the variable name, e.g:

echo "Today is the {$date}st";
