How can the syntax error in the provided PHP code snippet be identified and corrected for successful data updating?

The syntax error in the provided PHP code snippet can be identified by carefully reviewing the error message given by the PHP parser. Once identified, the error can be corrected by fixing any missing or misplaced punctuation marks, such as missing semicolons or parentheses. Additionally, ensuring that all variables and functions are properly declared and used can help prevent syntax errors.

// Incorrect code snippet with syntax error
$query = "UPDATE users SET name='$name' WHERE id='$id'"
$result = mysqli_query($conn, $query);
```

```php
// Corrected code snippet
$query = "UPDATE users SET name='$name' WHERE id='$id'";
$result = mysqli_query($conn, $query);
