[PHP] ob_start("ob_gzhandler") and error handling functions
Hi,
I include a php file at the beginning of every web page in this site.
This include file has an error handling function and starts output
buffering...
// Start of Error Handler
error_reporting(E_ALL ^ E_NOTICE);
ini_set('log_errors','1');
function ErrHandler($err,$err_string='',$err_file,$err_line)
{
// Do error logging thang
ob_end_clean();// Clear buffer
include('/path/incs/errors/errors.inc');// Output friendly error
page
exit();
}
set_error_handler('ErrHandler');
// End of Error Handler
It works great and the error handler kicks in if there is an error on
the page and outputs a friendly page instead. I really wanted to gzip
the pages by using ob_start("ob_gzhandler") but it doesn't work. I think
it is because of the error handler function trying to clear the buffer
(see the line ob_end_clean() which I assume becomes
ob_end_clean("ob_gzhandler") ). It says on the php functions page-
*ob_start()* may not be called from a callback function. If you call
them from callback function, the behavior is undefined. If you would
like to delete the contents of a buffer, return "" (a null string) from
callback function.
As I am new to this- I don't really understand what it is trying to get
at. Is there a way of me using my error handler and evoking the
ob_start("ob_gzhandler") ?
Thanks.

Re: [PHP] ob_start("ob_gzhandler") and error handling functions
Hi again,
Just wandering if someone could help me on this one- I'm quite anxious
to get something together. As I said in the last email I just want to
use ob_start("ob_gzhandler") but it doesn't seem to work with the error
function. I think it might be something to do with not being allowed
within a 'callback function'- well that's what it says on the php
manual. The thing is I'm not sure what that means, I find that section
not particularly clear. Please can someone help!

[PHP] Altering subject of email in a pop3 mailbox
Hi all. Tried to find this and can't find any info. I am writing a spam filter to run over multiple pop3 mail boxes which will work on keywords and Bayesian. With a very high score the filter will simply delete the email, with a med-high it will back the email in a 'bulk-mail' folder and delete it from the mailbox. with medium score I was wanting it to append the keyword [spam?] to the subject line and keep it in the pop3 mailbox.

[PHP] display_errors off and custom error pages
I've spent the last couple of hours trying to work this out to no avail.
I have recently moved over to a managed dedi server and no can ask my
host to change my php.ini.
I have found out that the 'display_errors' in the php.ini is set to off
and error file logging is off.
I would like to be able log to file which is easy to do from the ini
file but also to show a custom error page if there is an error on one of
the pages.
I thought I would be able to use a custom error handler such as -
ob_start();
// custom error handler
function e($type, $msg, $file, $line) {
blah blah
ob_end_clean();
// display error page
exit();
}
set_error_handler("e");
But all I get is a blank page. Does having display_errors off mean that
I can't use a custom error handler? I have also tried adding
*set_ini*('*display_errors*','1') but this keeps giving me a blank page.
Can someone tell me the best (and most secure way) of having custom
error pages in php. Ideally I would like it all set from a central place
so that i only need to change one file for all the websites on our
server. I didn't really want to change display_errors to on as I was
told this wasn't very secure- i don't want error messages on any of my
pages, I just want a simple error 500 server error page.
Many thanks,
Ian

I've checked and it isn't I have asked my host to do this now. However
I'd ideally like everything sorted from the Apache config file.
Because you can set all this stuff in an .htaccess file...

You do not need, nor even want probably, ob_start() just to be able to
use a custom error handler.
I thought I needed ob_start(), why don't I? If part of a page is
outputted then it would be impossible to output an error page as html
has already been sent out.
It doesn't HURT, mind you, but it's not needed at all.
// custom error handler
function e($type, $msg, $file, $line) {
blah blah
ob_end_clean();
// display error page
exit();
}

But all I get is a blank page.
Well, unless your "blah blah" section outputs something, all you COULD
get is a blank page.
Yes- blah, blah was just a nicely formatted and helpful error page that
won't scare off customers.
Does having display_errors off mean
that
I can't use a custom error handler?
No, not at all.
At the moment I have display_errors off and the above script does not
work for some reason. I have tried to put errors into scripts but all I
get is a blank page. The other question is do custom error handlers work
for parse errors? Again I would ideally like a custom error page to be
displayed for all errors including parse errors just in case I make a
mistake- I'm always forgetting those ';'s!
I have also tried adding
*set_ini*('*display_errors*','1') but this keeps giving me a blank
page.
I don't know where the *s got in in this email- I didn't type them!
Anyway it is still giving me a blank page
What are all those * characters in there? Get rid of them.

error pages in php. Ideally I would like it all set from a central

.htaccess, if it is on, will do this, and not require you to remember
to 'include' the error_handler on every script.
I didn't really want to change display_errors to on as I was
told this wasn't very secure-
That is correct.
It is too likely to expose too much information to Bad Guys.
i don't want error messages on any of my
pages, I just want a simple error 500 server error page.
I thought I might be able to do this by setting an error 500 header with
php using the header() command.
Whoa.
Okay, now we are in a different kettle of fish...
I dunno that you CAN force a "500 server error" from within PHP...
I guess there ought to be a function for that somewhere, but I've
never noticed it...
It would probably be documented or linked from or discussed in the
User Contributed notes at http://php.net/header though, if it does
exist.
Would you settle for a nice HTML output like:
An error has occurred. Please try again later.
Because that's pretty much a no-brainer with the error handler -- But
you have to actually output that.
I think your basic problem right now is the assumption that PHP exit()
with no content output would somehow constitute a 500 server error.
It doesn't.
[shrug]
There's nothing inherently "wrong" with the webserver returning a
totally blank document, really. Well, okay, by strict definitions of
HTML w3c standards, it's not valid HTML.
Good point- web standards are the way forward!
But it's also not a 500 error either.
As far as Apache is concerned, the document is "fine" and returns a
200. It just happens to be an empty/blank document is all.
Blank pages aren't that helpful to a user though.
Many thanks for your help.

Sounds like a parse error (using the code above will give you that).
Try it in a htaccess file:
php_flag display_errors 1
(I think).
You can't use ini_set because a parse error breaks the whole script
and it's not executed, so you need to change this value before the
script.
Do I have to have display_errors set to 1 if I want to display a custom
error page? I'd rather have display errors set to 0 but have a custom
error page displayed when an error is triggered. Is this possible?
Perhaps I have misunderstood how errors work in php.

Good idea...
also the check the ini setting auto_prepend_file, which can be

Wow- didn't know about auto_prepend_file. That is a great setting-
thanks for letting me know about it.
also apache has the ability to set a custom handler for 'real'
500 errors. the apache directive is something like:
ErrorDocument 500 /path/to/my/500.php
where the path is a url (or a local path - I think)
// display error page

set_error_handler("e");

[PHP] running conditions while looping through arrays....
I want to run filters on an pop3 inbox.
I have the following arrays which I'll get from the database-
$subject
$email
$body
$subject_like
$email_like
$body_like
I then go through each email in turn using this loop-
$popy = "{".$pop3."/pop3:110}INBOX";
$mailbox = imap_open($popy, $un, $pw);
$num_messages = imap_num_msg($mailbox);
if ($num_messages <= $no_srch) {$rrt = 0;} else {$rrt =
$num_messages-$no_srch;}
for($i=$num_messages; $i>($rrt); $i--) {
What I want to do is to check if the email address or subject or body of
each email is exactly like any of the details stored in the arrays
$subject, $email, $body and to check if the email address or subject or
body contains a word or phrase from the arrays $subject_like,
$email_like, $body_like.
For example-
$subject[0] = "SPAM"; $email[0]= "";
$body[0] = "";
$subject_like[0] = "";
$email_like[0] = "";
$body_like[0] = "";
// If the subject of the email = "spam"
$subject[1] = ""; $email[1]= "[EMAIL PROTECTED]";
$body[1] = "";
$subject_like[1] = "";
$email_like[1] = "";
$body_like[1] = "";
// if the email address of the email = "[EMAIL PROTECTED]"
$subject[2] = ""; $email[2]= "";
$body[2] = "spam body text";
$subject_like[2] = "";
$email_like[2] = "";
$body_like[2] = "";
// if the body of the email = "spam body text"
$subject[3] = "SPAM"; $email[3]= "[EMAIL PROTECTED]";
$body[3] = "";
$subject_like[3] = "";
$email_like[3] = "";
$body_like[3] = "";
// if the subject of the email = "SPAM" AND the email address =
"[EMAIL PROTECTED]"
$subject[4] = "SPAM"; $email[4]= "";
$body[4] = "";
$subject_like[4] = "";
$email_like[4] = "";
$body_like[4] = "spam text";
// if the subject of the email = "SPAM" AND the body contains "spam text"
If any of the above conditions are met then the email message is then
stored in a database and deleted of the POP3 server.
Is there a quick way of doing the above? The only way I can think of is
by looping through each array for every email. This is really really
slow. I'd be grateful for some help here

[PHP] complex control structure- please help
Hi all,
This may not be complex at all- maybe my head is just screwed up this
afternoon!
I am looping through arrays all at one time for the following-
$filter_subject
$filter_body
$filter_email
$filter_subject_like
$filter_body_like
$filter_email_like
Examples of the following could be-
$filter_subject[0] = "This is the subject";
$filter_body[0] = "This is the body";
$filter_email[0] = "[EMAIL PROTECTED]";
$filter_subject_like[0] = "";
$filter_body_like[0] = "";
$filter_email_like[0] = "";
$filter_subject[1] = "";
$filter_body[1] = "";
$filter_email[1] = "";
$filter_subject_like[1] = "lots of nice things";
$filter_body_like[1] = "horrible body text";
$filter_email_like[1] = "[EMAIL PROTECTED]";
$filter_subject[2] = "";
$filter_body[2] = "";
$filter_email[2] = "";
$filter_subject_like[2] = "Lots of nice things";
$filter_body_like[2] = "";
$filter_email_like[2] = "";
$filter_subject[3] = "";
$filter_body[3] = "This is the complete body";
$filter_email[3] = "";
$filter_subject_like[3] = "Part of the subject";
$filter_body_like[3] = "";
$filter_email_like[3] = "";
I then run something like the following on the variables $subject,
$body, $email, $subject_like, $body_like and $email_like
for($e=0;$e
if($subject == $filter_subject[$e])
{$found_subject = 1;}// Subject has been found
if($body == $filter_body[$e])
{$found_body = 1;}// Body has been found
if($email == $filter_email[$e])
{$found_email = 1;}// Email has been found
if(strpos($subject_like, $filter_subject_like[$e]))
{$found_subject_like = 1;}// Subject(like) has been found
if(strpos($body_like, $filter_body_like[$e]))
{$found_body_like = 1;}// Body(like) has been found
if(strpos($email_like, $filter_email_like[$e]))
{$found_email_like = 1;}// Email(like) has been found
...
}
What I want to do is work out if (from the above examples) the following
(not written in php by the way, just in kind of english)
example 0 -
if - ($subject == "This is the subject" AND $body == "This is the body"
AND $email == "[EMAIL PROTECTED]") THEN DO THE FOLLOWING
example 1 -
if - ($subject == "lots of nice things" AND $body_like contains
"horrible body text" AND $email contains "[EMAIL PROTECTED]") THEN DO THE
FOLLOWING
example 2
if - ($subject contains "Lots of nice things") THEN DO THE FOLLOWING
example 3
if - ($body == "This is the complete body" AND $subject contains "Part
of the subject") THEN DO THE FOLLOWING
How can I organise a control structure so that I can do the above? My
brain is hurting and I could do with some thoughts from you guys!
