Are both same in PHP?

Are these both same?

$this->query($result, $connection);
return $result;

and,

return $this->query($result, $connection);

First code works fine, but, when I am running last code, I am getting error.
Is it possible?

I think both are same…
Isn’t it?

Someone please…

No, they aren’t the same.

The first code calls the query method, then returns the $result variable. The second code calls the query method, then returns whatever the return value of that method was.

3

they’re not even close to the same.

the second returns the output of whatever the query method does.

the first returns whatever $result is - a variable or a resource.

Thanks to all of you.
This was my silly mistake.
Yes, You all are right.
