What is the difference between declaring:
$myArray = Array();
and:
$myArray = [];
There's no difference, it's just two alternative syntaxes. See https://www.php.net/manual/en/language.types.array.php

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.

Is foo[] an array?
In the following code is an array element being assigned to foo[]? And is there an array key that is automatically associated with it?
$this->foo[] = 'hello world';
This is adding an element to the end of the foo array.
It's the same as using array_push().

$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.
