Hi All,
Ok, before we start, I know this topic has been flogged to death on how
to load images from a database using PHP. So, before we start, I have
had this method of loading images in this way working for years. :)
However, the problem I've come across has given me a major headache and
can't find a solution to the problem.
So on to the problem....
I have 2 servers (setup details below). Server #1 loads the images from
the MySQL database using PHP perfectly. However, Server #2, which has
identical versions of Apache, MySQL, PHP and were compiled with the
exact same parameters, doesn't want to even bother working. The PHP
scripts just outputs a bunch of text, which I have seen before if
certain headers are incorrectly built. However, there is no difference
in the installation of the software, apart from the OS and that fact
that Server #2's MySQL RPM was built specifically for Redhat Enterprise 4.
Server #1
================
Fedora Core 2 (fully patched)
Apache 2.0.55 (compiled from source)
MySQL-4.1.5 (RPM glibc 2.3)
PHP-4.4.1 (compiled from source)
Server #2
================
Redhat Enterprise 4 (fully patched)
Apache 2.0.55 (compiled from source)
MySQL-4.1.5 (RPM Redhat Enterprise 4 version)
PHP-4.4.1 (compiled from source)
If I export the data from the MySQL database into a file and then call
it from the browser, the image shows perfectly, so we're not dealing
with corrupt data. I use SQLYog to also administer the databases,
viewing the BLOB field using this tool allows me to view the image
stored, and it shows perfectly well.
Data returned from "httpd -l", "httpd -V", "php -v" and "php -m" show
identical builds.
Has anyone come across this problem before? Also the httpd.conf and
php.ini files are identical in everyway, apart from IP addresses.
Many thanks,
Kevin Smith

Did you double check in the phpinfo() output for each server that the
php.ini is being loaded for where you think it's being loaded?

HI Robert,
I have checked both phpinfo() and php -i via the cli as follows and both
produce the expected results. Also phpinfo() shows the exact same
"Configure Command" data for both servers.
Server #1
[rootde006102 limiteds_v2]# php -i | grep ini
Configuration File (php.ini) Path => /usr/local/Zend/etc/php.ini
Server #2
[rootS76017 domains]# php -i | grep ini
Configuration File (php.ini) Path => /usr/local/Zend/etc/php.ini
Also both php.ini files have PHPSESSID specifically set to only work
with cookies. If this was not the case, the website wouldn't work very
well, which the sites do, apart from the images on Server #2. :(
Any other ideas? This is a very strange one.
To show you what happens, here's the site that works and the one that
doesn't:
Server #1 (working)
http://www.limiteds.com/includes/image_load.php?image_id=8522&field_id=image_full_2
Server #2 (sad and not working)
http://www.limitedshop.co.uk/includes/image_load.php?image_id=8522&field_id=image_full_2

Kevin

The headers aren't the same, specifically the second one doesn't send
the type as image/jpeg.

Oh and also, you really should check the output of the phpinfo()
through the browser, the php cli file could be reading a different
file.

PHP by default uses cookies.

Hi Curt,
In that case, what on earth is going on. This is the script which is on
both servers: However, I noticed that if I moved the following lines to
the top of the script:
header("Content-Type: image/jpeg");
header("Content-Transfer-Encoding: binary");
..and hard-code the mime type, it outputs the correct headers, apart
from "Transfer-Encoding:chunked". Which seems to still screw it up.
The content length is wrong (13198), it should be 13184. Looking at the
RAW output of the image data, there is a difference. I noticed 3381 was
output as part of the image data, yet this is not so on the Server #1,
that works. Even if I fix the content-length header to what it should
be, it still has some differences.
It still bugs me that the data is absolutely fine in the database, as I
can save the data out of it into a file and view that file as an image
with no problems at all.
Anything else you can think of?
Thanks,
Kevin

Solved!
I don't believe it, there was an extra carriage return in the require
file "housekeeping.php". This carriage return "is" present on Server
#1, but Server #2 obviously doesn't like it.
I am now going to stick my head out of my window and scream for not
thinking that that could have been a possibility.
Severely in need of some therapy.
Thank you for all your help, Curt and Robert!!!! :)

Personally, I present solution 2b. I also don't like the idea of
a(nother) templating language either. When doing html like this I also
like using short tags because it looks better and the colon syntax for
ifs as I find it easier for non-programmers and easier to follow in
large blocks of html. That should be enough to get everyone here screaming.
I would also wrap this file inside a layout script and/or use prepend
and append files. Depending on the overall use I'd consider pushing
some of it into another file. There is too much php code in there at
the moment.

Hi!
I found the solution to my prob. SELinux was enabled in the server
which needs disabling. After disabling SELinux it was working great.
Thanks for your help guys.
Another small query though, is there anyway to enable SELinux and as
well use shared memory between PHP and C++? I know using Zend engine
would solve the prob, but we need to buy zend which is very costly for
me, any other solution is welcome.

Let's do it this way... What are the rules for a valid callsign?
i.e.
- If it's only three characters, it must start with a letter.
- All callsigns must have both alpha and numeric components.
- A callsign can not have to identical letters next to each other
- A callsign is always written in uppercase
etc.
If we know what the rules are that constitute a valid callsign, then
we can help you write a regexp.

Basicly, you see an example of each different type of callsign. Other
than the patterns you see above there are no real rules. A letter in
the example above means that there can only be a letter in the spot
and a number in a spot means there can only be a number in that spot.
There are 7 different formats and you see the one above.
Did you see the regex I had in a previous post?
Thanks for your response.

It is trying to make the xml.lo file, the errors prior to that

This is an odd configure line, i'm guessing this is some sort of
package thing. At first glance at the the errors above, i would
guess that this package has some version issues.

If you are using the framework I'm not sure how it talks to a
database matters.

What timezone are the users expecting the time to be displayed in?
Do they get to specify what TZ they are in?
For starters i would suggest looking into the setlocale() function.

There a few things wrong with it as well.

Problem #1
- with those spaces in the expression i would assume it really
needs to have the /x modifier, i would hardly thing that anyone
will type:
' c zirzow gmail .c '
- it doesn't consider emails like foofoo.us.gov
I think there was a 300+ line regex to catch all cases, posted
earlier.

Problem #2
- an MX record isn't required to deliver email. Try a:
nslookup -type=MX zirzow.dyndns.org then send an email to
curtzirzow.dyndns.org, i will get it.

Problem #3
- MX hosts dont *have* to resolve to the same host it is doing
mail for, it generally does resolve that way, in most cases.

Uh.. well, i hope problems 1-3 should contribute to its (un)usefulness.

Hi!
I would like to know what does the community think of the best
architecture for server client communication and why? That is, if
there is a server in C++ (say a game server) and the PHP has to 'read'
data 'from' the server then what is the best form of communication?
a) Shared Memory : Server opens the shared memory in write and the PHP
scripts open it in read and gets the data
b) TMPFS (just like shared memory): Server opens a file in tmpfs in
write and PHP in read
c) Databases: Server Updates a table in the DB and client reads from the table
d) Files: Same as TMPFS
Regards,
Yaswanth

my friend here forgot to add that it will be a pretty busy website
with lots of requests.
And i would also like to know if there are any other forms of
communication other than the 4 that my friend here specified. Anything
that you people think will be efficient.
