Why doesn't this record $limit = "Limit {$limit+5}" work?

Question

PHP

Gives an error: Parse error: syntax error, unexpected '+', expecting '}'
Is it possible to perform arithmetic operations somehow in a string?

Answer 1

because you can't do that php.net/manual/en/language.types.string.php#langua...

Answer 2

Using double quotes and curly braces is bad design.
Write normally:
$limit = 'Лимит ' . ($limit+5);
