New Mysqli Object is Null
I just started with building my database class for my MVC framework. While building this I am experimenting with simple queries and tables in order to make it work properly.
I was trying to query the following:
SELECT * FROM mvc_test
This should return 3 rows:
1 | test
2 | test2
3 | test3
I use the following method to query:
<?php $this->result = $this->conn->query($this->q); ?>
Where $this->conn is:
<?php
$this->conn = new mysqli($this->reg->conf->database['host'],
$this->reg->conf->database['user'],
$this->reg->conf->database['password'],
$this->reg->conf->database['database']);
?>
Where $this->reg->conf->database contains all the values for host, database etc. This works, I have a connection.
Now, when I var_dump the result like this:
<?php var_dump($this->result); ?>
I get this:
object(mysqli_result)[9]
public 'current_field' => null
public 'field_count' => null
public 'lengths' => null
public 'num_rows' => null
public 'type' => null
But, as said before it should contain at least 3 rows, so I would expect num_rows to be '3'.
Now, when I var_dump the num_rows of the result like this:
<?php var_dump($this->result->num_rows); ?>
I get a 'int 3' as response.
Conclusion: in the first var_dump it's null, but with a deeper inspection I get a 3. So it reads 3 rows. When I add another row (the 4th), it returns a 4 as expected.
My question is: why is the var_dump not working properly? Why Does it say null at first, but with a deeper inspection it does have a value.
Thanks in advance, I'm really struggling with this one since I don't get any errors as well.
