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 does "->" mean/refer to in PHP? [duplicate]

Closed 9 years ago.
$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.

hi
Why is it that some php functions have a '&' in their signature for example
function &getData()
It returns a reference to a variable.
