    The top line is effectively checking if the parameter $sum is set 'isset' and together with the md5 part is checking if the value of $sum is a certain value. md5 is kind of security command that returns the hash value and is used to encrypt sensitive data such as passwords. If the value matches the hash, the file 'upgrade.php' is executed and $switch is set to 2. What these last two parts do is impossible to tell without seeing the entire code.
