Unfortunately, I don't know how to write an extension or intentionally
perform a segmentation fault.
If I did know how to intentionally perform a segmentation fault, wouldn't
that be enough to generate a 500 error in a single php file without needing
to be in an extension?

You can search for a buggy extension that has known issue of segmentation
faults.

By the way, You can also try sending proper html page and http header that
will copy the Internal Server Error.
That is completely possible in php.
Just use the header() function.

Actually, I learned from reading a previous message on this list (Subject:
"php causes HTTP 500, but results in blank page in apache"), that using
header() would require me to provide the content of the error page.
That probably should still put a message in the error log, but it wouldn't
be enough to convince the stupid tech support people at GoDaddy that it was
an error.
I want them to see their own error page and then fix the problem with the
logging.

Here's the problem. My site has this error intermittently and I'd
like to monitor the error log to figure out the problem.
Unfortunately, I don't get to see the actual Apache error log and my
hosting provider's error reporting system isn't working. Customer
support just sends me canned responses stating that everything's fine
and they can't reproduce the error, so I'd like to create a
reproducible internal server error so that they can see that it's not
showing up in the error log.
I know that I can mess up something in the .htaccess file, but that
would break the whole site. I don't want to do that.
I know I could use header("HTTP/1.1 500 Internal Server Error"), but
that means I would also have to provide the content of the Error 500
page. I want to kick off they're internal server error page. They
don't give me to option to create one of my own.
I'm using GoDaddy.
Can someone suggest some invalid PHP code that should generate an
internal server error?
Thank you.
I don't think it's that hard to generate an Internal Server Error. If
you have error reporting and such turned off and your code contains a
syntax error, that results in an Internal Server Error...

Quickest way I know of is to mess up an .htaccess file!

Another good way to do it on shared hosts is to give a file incorrect
permissions and try and access it

That does it perfectly, thank you. It seems very likely that the unwanted
characters were coming out of my jumbled logic somewhere..

Hello List
I want to use Cake PHP ,I have downloaded it from it's site,rename the
folder to first_app
and copied it to
/srv/www/htdocs
my root is here:
/srv/www/htdocs
by entering http://localhost/first_app/
it has some errors like these outputs:
Warning: _cake_core_ cache was unable to write 'default_en-us' to cache in
/srv/www/htdocs/first_app/cake/libs/cache.php on line 295 Warning:
_cake_core_ cache was unable to write 'default_en-us' to cache in
/srv/www/htdocs/first_app/cake/libs/cache.php on line 295 Warning:
/srv/www/htdocs/first_app/app/tmp/cache/persistent/ is not writable in
/srv/www/htdocs/first_app/cake/libs/cache/file.php on line 299 Warning:
/srv/www/htdocs/first_app/app/tmp/cache/models/ is not writable in
/srv/www/htdocs/first_app/cake/libs/cache/file.php on line 299
I wanted to identify another root in default-server I used this one:
<Directory "/srv/www/htdocs/first_app/app/webroot">
AllowOverride All
Options FollowSymLinks
# Order deny,allow
# Deny from all
</Directory>
I restarted the apache but again the same warnings
then I changed httpd.conf too.
I tried hard to figure it out.
if it is about the permissions I tried this one:
chmod -R 0755 /srv/www/htdocs/first_app/
would you please tell me how to change the root correctly?
or if it is not related to it What is the problem?
Thanks in Advance.

Try
$ chown -R www-data:www-data /srv/www/htdocs/first_app
Replace www-data:www-data with what is appropriate on your system.

Thank you, I found that only the tmp directory must be writable then I used
this one:
also by right clicking and using wwwrun for user I tried to set them as you
told
chmod -R 0777 /srv/www/htdocs/first_app/app/tmp/
and the I get fatal Error:
<http://cakephp.org/changelogs/1.3.6> Fatal error: Class 'Debugger' not
found in /srv/www/htdocs/first_app/cake/libs/view/pages/home.ctp on line 26

cool I found this hidden file .htaccess:
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteRule ^$ app/webroot/ [L]
RewriteRule (.*) app/webroot/$1 [L]
</IfModule>
well I don't know that this apache module is enabled or not I changed the
apache2 in /etc/sysconfig and add the rewrite in modules right here:
APACHE_MODULES="actions alias auth_basic authn_file authz_host
authz_groupfile authz_default authz_user authn_dbm autoindex cgi dir env
expires include log_config mime negotiation setenvif ssl suexec userdir php5
rewrite"

Hi,
I have implemented a "remember" me feature in my login-script, but I can't get
it to function!
I want to make it possible for the users to stay logged in for 30 days.
This is what I got this far:
This checkbox is placed Inside the index.php script, near by the
username/password field.
<p><input type="checkbox" name="remember">Remember me</p>
This is all I have added in the index/login script that has something to do
with the remember me feature.
When it comes to saving the username/password to cookies, I have added three
parts to the connextion.php script, all highlighted.
Obviously, I have not found out why this feature does not work, but I might
have placed the different if-loops in the wrong places, or it could be that the
if-codes are not correct themselves?
Anyways, all help are appreciated.
Cheers!
