[add two dot before and after a variable]

Thank you

[add two dot before and after a variable]

Just use the second one variable interpolation. Why people consider using the first one concatenation ? Much more lengthy. The two dots are with the variable and not with the string.

[add two dot before and after a variable]

why sometime written in this way    $message = '    Payment status: '.$payment_status.'    ';

Sometime in another way  $message ="    Payment status: $payment_status  ";  more simple and better
