PHP print statement returns a value of integer type which is always 1, regardless of what argument you give the statement. That’s the source of the extra 1. Read more about echo and print here: https://www.jquery-az.com/php-echo-and-print-statement-with-6-examples/

Answer 2

Airree maybe

Answer 3

It's from PHP challenge

Answer 4

It's a function. The dots are not a part of it, it's just to concatinate it with the 2 1's. It just outputs something on a screen, and returns it

Answer 5

Airree Why print(1) or echo print(1) does not work?

Answer 6

Airree Why echo 1 .print(2). 1 is 2111?

Answer 7

1. It does work.
2. It doesn't return the number I guess, but 1. So, it will be 2111

Answer 8

".” the point is a concatenation operation on strings. php considers the “1” as chars and put them together as 111.

Answer 9

The print function prints its argument then returns it. So if you think about it, first, you print 1, then you echo 1.1.1, which is 111

Answer 10

What is .print(1). ?
