TT.This means: Using curly braces, the parsing speed is approximately 23 times times the use of discontinuous single quotes.Conclusion: In single quotes, multiple variables (or a small amount of data) are represented, as possible, with double references and curly braces.The second set of experimental data shows that "... $abc $abc$abc ..." than ' ... $abc. $abc. $abc.
