We can ommit the ">0" in $uid po... having a condition of 
```php
if ($uid && count($info)) {
```
is the same po.
or we can revise it into something like this
```php
if (!$uid && !count($info)) {
     throw new Exception("Error in editing user's information.");
}
// all your code inside the previous if condition
```
With this code po we can omit the else block and having only if condition, the main idea here po is to evaluate if an error may occur if yes then immediately throw an exception. Basta di na po tyo magproproceed sa ibang code pag may mali agad. Mas maganda ung lahat ng error handling ay ginagawa na sa first part ng function
