Print only 0

The specific number is determined by the input parameter n

Print 00000 as N=5

Print n 0 based on n value

Print a line 0101010101010101010101

The specific number is determined by the input parameter n

such as test.php?n=3 printing 010

print 010101 based on n value ...

Make a calculator.

such as Test.php?a=1&b=2&operator=jia output 3

such as Test.php?a=5&b=2&operator=jian output 3

such as Test.php?a=2&b=5&operator=cheng output 10

such as Test.php?a=6&b=3&operator=chu output 2

 Php$a=$_get[' A ']; $b=$_get[' B ']; $operator=$_get[' operator ']; functionCalculate$a,$b,$operator) {        Switch($operator) {             Case' Jia ':$result=$a+$b; return $result;  Break;  Case' Jian ':$result=$a-$b; return $result;  Break;  Case' Cheng ':$result=$a*$b; return $result;  Break;  Case' Chu ':$result=$a/$b; return $result;  Break; }    }    EchoCalculate$a,$b,$operator);?>
