Answer 1

First Read This Documentation

Notice the WHERE clause in the UPDATE syntax: The WHERE clause specifies which record or records that should be updated. If you omit the WHERE clause, all records will be updated!

$sql = "UPDATE table SET field = '$variable',field2 = '$variable2'";

In Your code problem is in your update query. check that manualy.
