Description:
------------
When I use fgets() it returns the line, and the next one...

Correct me if I am wrong, but when you ask for one line, it should return one line?

There is not even a function (that I have found yet) that returns ONLY 1 line...

fgets should not be adding a /r/n at the end, that should be up to the programmer...

Reproduce code:
---------------
---
From manual page: function.fgetss
---

$fp = fopen("AD_SYSTEM/popup.ads",'r'); 

while($line=fgets($fp)) 
{ 
//add the link text to the array
$ads[] = $line;
}

 
fclose($fp); 

echo $ads[1];

Expected result:
----------------
"http://somepopup.url/advertisement.html" (without quotes)

Actual result:
--------------
"http://somepopup.url/advertisement.html
" (without quotes, notice the 2nd line)

I was looking at fread() just now, but it requires a length...

I dont want to specify a length.

I am looking for the equivalent of readLn() from some other language i know (forget which one) where it reads the entire line, and only outputs that one line... Meaning there is no new line after the line I requested...

As per the docs, fgets() returns the newline character that it reads.  That doesn't mean there are 2 lines.  It is a single line terminated by a newline character.  If you don't want that newline character, trim() it off.

You can use trim with no args and it cuts the newline out?

See I was used to the newline not being there... And no one has mentioned that method anywhere... I googled for that for hours on end and there are always people asking that but no solutions...

Thanks, now I can resume that part of my work! <3 PHP
