Answer 2

String's a data type containing charsequences. It can store values as "abc" or "Hello World". It can contain also chars which are numbers, but, that's important, it contains them as Strings: "hello 10"
$string = "hello world"; does not output anything, cause you didn't print it out:
echo $string;
//output: hello world

Answer 3

character you put inside "_" or '_' is called string. it can be any alphabet or number.
for example : print ("hello world") output is hello world
print ("10" + "4" ) output is 104
