[PHP] Server-initiated HTTP requests
I'm using php to have several servers communicate between eachother. I want to do the following: Server A sends a request to server B. Server B stores some information about this request, and sends back a response to A (so far it's regular HTTP). Next, server B must send an HTTP request to server C. How can I initiate an HTTP request to server C with PHP? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

If you want to be totally searchengine-safe, do not use variables on the url, do not rely on cookies and do not rely on POST variables for the pages you want to have the searchengine spider. Also, you could make a robots.txt file and instruct the searchengines to spider only particular pages on your site. -Sander -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

It's something that would piss me off :) (Making me work, right click to find the real url I want to bookmakr, etc.) DHTML can do something like you want, but its complicated and not standard. (You can load the contents of URL A in a hidden frame, then replace the contents of the current document with the contents of the hidden frame.) Just forget about the whole idea already, each individual page should have an unique url, and that's the way it's supposed to be. -Sander -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

RE: [PHP] Forcing htaccess login again
The request for a password is usually generated by a 401 header. Just do
this -
Header("WWW-authenticate: basic realm=\"Some realm\"");
Header("HTTP/1.1 401 Unauthorized");
exit;
That should pop up a box. Just make sure you check the values of
$PHP_AUTH_USER/PW first before presenting those headers.
This is more of an http question then it is a php question, I strongly
advise you to read and understand the HTTP/1.1 rfc - it can be found at
http://www.faqs.org/rfcs/rfc2616.html
(See chapter 10.4.2 for the documentation of the 401 header)

RE: [PHP] What's XML's Purpose??
XML, IMHO, can best be regarded as a layer between the real data and the application. We used to make up new formats for allmost every type of data exchange. Every type had its own format, its own parser, and because of that the same mistakes were made over and over again. Some formats weren't extensible. Parsers contain(ed) bugs. XML solves all this. If your data is suitable to be encapsulated in xml (meaning its not binary data and a little tag-overhead isn't a big deal) there is no need for these mistakes anymore. You can use a trusted, standard format, which is extensible and readable, and you can use standard tools to read and write the data. (no more, or at least less, bugs in parsers.) -S -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
RE: [PHP] Which is better coding style...
Definitely the second style :)
(If we were talking about C(++) then the first would have even been
forbidden by my companies coding standard as well as several coding
standards of other companies I worked for.)
The reason is this - a function has one entrypoint (duh) and one
exitpoint. Jumping out of a function somewhere in the middle leads to
unmaintainable code, and bugs when extending that function and that
return is overlooked. But, as with the indenting and bracket placing, it
is a matter of religion. They would have to torture me for three weeks
to get me to place the brackets like you did in your example :)
function blah()
{
$retval = "";
switch( $bob )
{
case 1:
$retval = "this";
break;
case 2:
$retval = "that";
break;
default:
$retval = "other";
break;
}
return $retval;
}

The only problem I have is that the tables are very difficult to handle. I want to make 4 tables in a row (so that will be 4 dif categories with bookmarks) and after that, the next table should start under the first one. Like this categorycategorycategorycategory xxx xxxxxx xxx xxx xxxxxx xxx xxx xxxxxx xxx categorycategorycategorycategory xxx xxxxxx xxx xxx xxxxxx xxx xxx xxxxxx xxx (x = a weblink ;-) The (dutch) website where you can find a full example for what I mean: http://www.startpagina.nl/ Can anyone help me with this please?

[PHP] counting with dates (help!)
Hello,
This is my problem:
$today = date("Ymd", mktime(0,0,0, date(m),date(d),date(Y)));
$last_week = date("Ymd", mktime(0,0,0, date(m),date(d)-7,date(Y)));
echo ($today - $last_week);
The result is a number like 8876 (20020107-20011231 = 8876)
But in date thinking it should be 7!
How can I let php count in real days/month/years in stead of numbers?
Maybe this is a silly question, but anyone who has the answer would help
me very much!
Thanks in advance!

[PHP] variable operators in queries
Hello,
Is it possible to put variable operators in queries?
I tried this (the real variable comes from a form)
$Date_Operator =(">=");
sql="SELECT * FROM poeple WHERE age $Date_operator 20";
$result_id = mysql_query($sql);
It doesn't work like this. I also tried:
sql="SELECT * FROM poeple WHERE age \"$Date_operator\" 20"
$result_id = mysql_query($sql);
it didn't work either.
Or should I use a have to make a IF-Then construction?
If $Date_Operator == (">=")
then
{
sql="SELECT * FROM poeple WHERE age >= 20"
}
etc...
Can anybody help me with this?
Thanks in advance!

[PHP] PHP passthru() blocks with bash process replacement?
Hi all, I have a problem with PHP passthru() blocking when it is supposed to start a daemon and return. I have a Node.js daemon with a bash script wrapper around it. Users can call this bash script directly, but it is also used by our deployment system. Our deployment system uses Phing, and Phing uses `exec()` and `passthru()` internally to cann external programs. The bash script wrapper around my Node.js uses a bit of process replacement because my Node.js server can't directly log to syslog. Normally I'd start Node.js like this: forever -l app.log app.js But because I want it to log to syslog, I put this in the bash script: forever -l >(logger) app.js The `logger` process replacement creates a file descriptor into syslog like /dev/fd/63 whose path is passed to the forever command as the logfile to use. This works great when I start the daemon using the bash script directly, but when the bash script is executed using PHP passthru() or exec() then these calls will block. If I use a regular logfile instead of the process replacement then both passthru() and exec() work just fine, starting the daemon in the background. I have created a complete working example (using a simple PHP daemon instead of Node.js) on Github's Gist: https://gist.github.com/1977896 (needs PHP 5.3.6+) Why does the passthru() call block on the process replacement? And is there anything I can do to work around it? Kind regards, -- Sander Marechal -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Really, when you've read http://www.faqs.org/rfcs/rfc2616.html you'll be able to understand a lot more about how http requests and responses work, and how stuff like compression fits into the picture, etc, etc. Basically a must-read for anyone serious about working with the web on a technical level.

[PHP] Apache 2.0.52, PHP 5.03, FreeBSD 4.10 memory problems
I'm running Apache 2.0.52 and PHP 5.03 in a jailed (Virtual Private Server) FreeBSD 4.10 envirorement. PHP 5.03 is running as php_mod and was installed quite recently. Since then (better, since someone started using it) I've been getting these errors in the httpd-error log: Allowed memory size of 8388608 bytes exhausted (tried to allocate 79 bytes) And this one in the php-error log: [06-Feb-2005 17:25:50] PHP Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 6587593 bytes) in xxx/xxx/xxx/xxx/xxx/xxx.php on line 53 I also see several thousands of notices in the PHP-error log within the time-frame of a single second, plus diveded by zero, etc. Of course, I asked the programmer to fix all of these issues.Among others, there was a script that outputted a html-form with 2 columns, 100 rows each containing select-boxes with 100 full names (and those 100 names were the same of every column/row in that form :-|). But the problem is not so much that someone is using broken and the most inefficient scripts, but more that they are crashing the entire box! When these scripts are run, the box becomes totally unresponsive, afterwards all cgi and php request to Apache fail with a 500 error and sometimes the whole box crashes completely, apparently from memory exhaustion. :-( It this a bug somewhere in PHP, Apache or FreeBSD? How can I protect myself against this? I can't manually check every script, and the memory and time limits in php.ini (20s for exe, 30s for input and 8MB for mem) don't seem effective here. What are my options to make Apache 2 and PHP 5 full proof against such scripts?

As it is a personal friend, it is an difficult situation. Getting him to write better code isn't easy, he's mainly interested in functionality and getting program done ASAP. > > But the problem is not so much that someone is using broken and the > > most inefficient scripts, but more that they are crashing > the entire box! > > That's definitely not good. Nope, and I can't figure out why. I've set the memory limits in php.ini plus some additional things in httpd.conf (RLimitMEM, etc), but for some reason, memory keeps getting consumed. What I find really troublesome is that it effects both php (running as mod_php) and cgi. After some time, cgi-scripts start failing too with: Out of memory during "large" request for 134221824 bytes, total sbrk() is 134369280 bytes., referer: ...

(one and a halve month ago, some clients on an other installation who hadn't mainted phpBB also caused me the necessary problems). Also, when clients are non-commercial, a good programmer is out of the question (which applies to this case too). I wonder how mass hosting companies get arround these issue's? Thanks for the input!

I could write a PERL-script for that :-) For wide-used scripts (such as PHPBB) automation would be a doable and good sollution, but for custom scripts, it will be quite a challenge. > When you find a client running known security flawed > software, you deal with them, quickly and politely, but with > clear cut no nonsense > requirements: > > Upgrade it now or lose the account. That would be the right thing indeed. Though I do find that many times, people either have severe technical difficulty upgrading (usually installing was already quite a tough cookie for them, being used to the more point and click of Windows). Or perhaps just to the fear of it. It always comes down to a lack of knowledge and understanding from the user.
