You have an error in this line:

$result=mysq1i_query($sql);

Its l not 1 in (mysq1i)

Correct one is:

$result=mysqli_query($sql);

And when you get this error Undefined Function it means you do not define this function in your code.

you have used on line no: 9

$result=mysq1i_query($sql);

instead of

$result=mysqli_query($sql);
