RE: [PHP] mail(): carriage return required??
I read the mail fine in my hotmail.com account, but when I read that same mail in my MS Outlook client the mail is one long line of text: "this is line 1 this is line 2 this the 3rd etc etc" I understand from this difference in layout that the 'carriage return' is required. Is there a function that adds a 'carriage return' after every 'newline' found in a string? Or is this another problem? Use \r\n for email line breaks. Should I write a function that replace any corrance of '\n' with '\r\n' in a string myself? Hard to believe that the PHP guys haven't encountered this before and didn't write some PHP function to do this for us, not?

[PHP] mail(): \r\n gives extra empty line between each line in Outlook
Hi all, First I had a problem that text from a textarea form object passed to mail() ended up as a single line of text in MS Outlook. I changed the newlines to newlines _with_ carriage returns: strtr($mailbody, "\n", "\r\n"); Now it's not a single line of text but every newline skips an extra line ?!?! The following is typed in the textarea en passed to mail(): "line 1 line 2 line 3" In Outlook it shows as: "line 1 line 2 line 3" The "\n" alone gives a single line of text, the "\r\n" gives an extra empty line between each line. (the "\r" alone ends up the same as "\r\n"). What is going on here? How can I fix this?

[PHP] Content-Type: image/gif and send the image in hex
Hi all,
I'm trying to make a demonstration script (using PHP) that demonstrates the
use of MIME types in HTTP headers. It should send the Content-Type header
and than sends an image to the browser in hex.
I run the script in my browser and get the bare decimal values displayed and
not the GIF image:
Content-type: image/gif
717370565597701024701280001280128128000128128012801281281921921921922201
92166202240643209632012832016032019
--snip--
I also tried to use:
header("Content-type: image/gif");
But no success.
I don't want to use the header() function cause it doesn't help my
demostration script show the workings.
Where does it go wrong? (See script below)
Regards;
Eelco.

RE: [PHP] Session With Cookies
no offense for anyone at all. I was just wondering myself and threw it in the group discussion. Eelco. I never wanted this question to be an offense for anyone. I thank you all for your answers. Regards PHPLover Lux [EMAIL PROTECTED] wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... It's unlikely I suppose, but there's a must-have book you should look at if you want info on hacks, including browser hacks (Hacking Exposed: Network Security Secrets and Solutions, 2nd Edition). The cookie hack that comes to mind only works in IE or MS products (but that's only what, 90% of the web), but all it is is a line or so of html code that somebody places on their site (say in an iframe...) that sends them all your cookie data (if the user uses outlook, they can also just place it in an email). from there, they use the cookie data to pose as that person on various sites trying to gain sensitive info. but if you're already giving them the password, how much more sensitive can you get? so really, if they don't close their browser for a while, this possibility increases. and it may be a slim possibility, but it's better to be safe than sorry. later lux Well .. I am ... nobody but the user itself can see the login and password in the cookie. Unless it's on non-SSL connection and somebody is packet-shiffing around. Otherwise there would be no leak for somebody else to get this information, is there? And if the user doesn't logout, the cookie is still destroyed when the browser is closed anyway.

RE: [PHP] % operator
It doesn't have a use in only PHP but in all programming languages.
It's a math thing .. u can get a remainder of a division.
10%8 = 2
12%8 = 4
10%5 = 0
12%5 = 2
Simple application:
$ppl = 23;
$grpsize = 7;
echo ("when $ppl people are divided over groups of $grpsize, ".
$ppl%$grpsize ." people are ungrouped.");
This operator can be used for more complex situations.
Cheers;
Eelco.
Hi!

RE: [PHP] Session With Cookies
This will store a cookie with a userid and an unique number ($token) as
session-id (??).
If I'm not mistaken, this session-id is not checked here. Thus serves no
purose. Anybody who retrieve the cookie from the cookie file on the system
can use it to resume the session (if done within the set 3600sec.). Even if
the browser has been closed.
In case of login/password required sites, I use the login and password as
cookie values and have _no_ expiredate set. Every time a request is made
_both_ cookie values (login and password) are checked with that on the
server. When the browser is closed, the cookie is gone.
It works but I think it's quite an unconventional way ... any
suggestions/comments on this method?
Cheers;
Eelco.
Try this:
// Set Cookie if not already set
if (!isset($user_id)) {
$token = md5(uniqid(rand()));
setcookie("user_id", $token, time()+3600,"/",".yourdomain.com");
}
look at the setcookie function on php.net to figure out all the
parameters:

[PHP] php_imap4r2.dll not loaded ?!?! (win2k)
Hello, I'm trying to use some POP3 functions and the manual states I would need to use the IMAP functions. So I uncommented the ";extension=php_imap4r2.dll" line in my "c:\winnt\php.ini" file. But it gave me the following error: "Unable to load dynamic library './php_imap4r2.dll' - The specified module could not be found". I read I needed the download install the "imap-4.5.tar" module. The README file has only instructions how to "make" it for UNIX. The default "MakeFile" is for UNIX. So I tried to clown around and rename "MakeFile.nt" to "MakeFile" and make it. But I only get errors: Could Not Find D:\temp\imap-4.5\c-client\LINKAGE.* NMAKE : fatal error U1077: 'C:\WINNT\system32\cmd.exe' : return code '0x1' Stop. NMAKE : fatal error U1077: 'C:\WINNT\system32\cmd.exe' : return code '0x2' Stop. I also tried this with the "MakeFile.ntk" (don't know what ntk stands for), but no fix. Can anybody help me with this problem?
