What are those brackets for?

Question

PHP

Tell me what {} are
for, for example like this

$x = "Что то";
"CREATE TABLE {$x} (id int not null auto_increment primary key, name text)";

Does this mean something or am I confused?

Answer 1

The brackets show the bounds of the interpolated variable. In this case, they can be omitted.

<?php 
$a = 'A';
$abc = 'ABC';

echo "$abc";   // ABC
echo "{$a}bc"; // Abc
echo "{$abc}"; // ABC
