$blabla->blab, just wondering what this means something to do with an object going into another?
Sorry for being a bit vague .
The arrow-like symbol has nothing to do with "an object going into another".
The syntax $blabla->blab means a call to attribute $blab in the object $blabla.
The syntax $blabla->blab() means a call to method blab() in the object $blabla.
Please read the Basics in PHP documentations.

I saw the line below in a class method :
return $return === 1;
What's the meaning of this ? As "===" is a comparaison operator, what would be the expected behavior of using this operator directly in a return ? Return only if 1 ?
Thanks

can you please help i just want to know why we use #in_array function.
$name = array("ravi", "ram", "rani", 87);
if (in_array("ravi", $name, TRUE)){
}
if (#in_array("ravi", $name, TRUE)){
}
The "#" symbol turn off the errors. It is not a good idea to use it.

what is the meaning of '??' operator in php?
I've seen someone using it like this. I've searched many results in google. But didn't found any solution.
$this->variable = $arg['value'] ?? NULL
?? is the new (since PHP 7) NULL coalescing operator. If the first argument is set and is not null it is returned, otherwise, the second argument is returned.

$title = l(
$comment->subject,
comment_node_url(),
array('fragment' => "comment-$comment->cid")
);
Ok, so $title is the l() function, and from what I'm reading, I am passing the $comment->subject argument to l() - is that correct?
What does $comment->subject mean? I'm looking all over and not understanding what it means. Is it an operator of some sort?
Sorry if this is a simple question - I just can't find the answer anywhere.
It's just an operate that indicates that "subject" is a property of $comment. You can read a bit more on the PHP manual.
