Answer 1

Case Sensitive

Case Insensitive
it doesn't matter if CAPITAL LETTER or small letter ,just write and run your code
$name;
$NAME;
both variables above are the same

Answer 2

case sensitive means you should carefully put name for variable, Constantine and function. for example if you write $Name = 1 and you user the variable with $name then it won't give you any value. you should call it with $Name;

while case insensitive you don't have to worry about the using of the capital letter or normal letter. both will be treated the same by the the program.

Answer 3

case sensitive means capital letters and small letters are considered different..for eg. "HELLO" and "hello" are two different strings.. while case insensitive means capital letters and small letters are considered as same.. Hello and HELlo are same in case of case insensitive
