What will be the output of the following PHP code ?
```
<?php
print_r "Hello Interview Mania"
?>
```

1. Hello Interview Mania
2. Missing semicolon error
3. Error
4. Nothing
5. None of these

Correct Option: C

The statement should be print("Hello Interview Mania") to print Hello world. Also if there is only one line then there is no requirement of a semicolon, but it is better to use it.
