Presumably you've already looked on www.php.net?

You can get the PHP logo and a Powered by Zend logo using phpinfo().

If you're using GET in your form(s) change it to POST.

Also, please do not reply to an existing thread and change the subject. This

AFAIK there are no built-in functions to do that. You need to run a query

Have you narrowed down the problem to whether the uploaded file is truncated

This should be the easiest to nail down. Add a bit of code so that when the 
file gets uploaded, it gets copied somewhere, then you can manually check its 
size. Obviously, if the filesize is OK then the problem is further down the 
line (probably the mail code).

  At a certain point in code, I run array_diff() on two arrays to produce a
  reduced version of one of the argument arrays. Problem is, I dont want
  the key-value associations to be preserved. I need that the returned
  array has new (integer, not string) indices in numerical order from 0...N
  without holes.
 
  Does anybody know how to do this? I have looked at different sort

  random selection with reduction of the sample set (i.e. with withdrawal).

just run your array through a foreach loop assigning each key-value pair to a 
new array.

 current bill status, pay a bill, enter new bills, etc.

It seems strange to me why anyone would want to do such a thing.

 I was wondering if anyone knew of an existing system that would do this for
 me, or if anyone had ideas as to exisiting systems that came close to the
 functionality I'm after - that I could tweak.

And it's even stranger that someone *has* come up with such a thing :)

I think I saw it on freshmeat.net.

I would always quote the value:

 Unfortunatelly array_search requires an array starting with 1. So php is

Haven't used this function before, but where does it say anything about

 Does anybody know a workaround for this?

You can do:

$my_array = array_flip($my_array)
$key = $my_array['search_item'];

 Usually the mail is delivered directly to a program rather than to a

What are you actually trying to do? If you're trying to make a mailing-list

Otherwise with sendmail you can use procmail. It's clunky but doable.

Use phpinfo() to see what predefined vars you can use to get your document

No, the user doesn't 'leave' your site, all the processing goes on behind the

 I have to write a system that enables payments via this service, but I'm

That is a perfectly valid declaration, but without knowing your intent one 
cannot say whether it is 'right' or 'wrong'.

The thing you need to remember with PHP is that unlike many other languages, 
by default variables are not global in nature. Thus in order to use a 
variable that is defined outside of a function you need to declare it like 
you have above.

 you can do it that way, but if you want to avoid calling global all
 the time you might consider this approach:

 $GLOBALS[foo] = 123;

  $foo = 123; # No need to use the $GLOBALS array when outside of a function

 function something()
 {
 echo $GLOBALS[foo];

 Yes so I've heard... One thing though.. I use PHP4.1.1... not 4.2.x

Read the changelog (or history). A lot of default behaviour has changed

Not necessarily, if you have a single 'word' (a string of characters with no

the length of that 'word'.

 Hi,

 I want to set up a check that the page cannot be exacted by calling from

 So I set

 if (eregi(members.php, $_SERVER['PHP_SELF'])) Header(Location,
 login.php);

 at the very top of members.php. But I am being redirected to login.php no
 matter if members.php was called from login.php. What's proper way of
 implementing this?

In your code, assuming your regex is correct it matches *all* the time, thus 
no matter how you get to members.php, you'll be redirected to login.php.

And do you really only want to let people access members.php directly after 
visting login.php? How about if they login, go to the members page then go 
somewhere else on your site, then try to go back to the members page and they 
can't!

I would suggest that you use a more robust mechanism, such as sessions, for 
allowing/denying access to certain pages.

  certainly won't follow those links.

 Can someone point me to hardware that is still in active use that can't
 handle javascript?

I don't think it's hardware that was problem with javascript.

 Similarly, can someone point me to a company that specifically disables
 javascript as 'corporate policy'?  Back in 96-97, the 'no javascript'
 argument held, and probably holds today some if you're targetting
 handhelds and other 'non standard' devices.  But if someone specifically
 disables Javascript these days, a good portion of their web experience
 will not be as robust as it would otherwise be, and they probably won't
 notice that using your site is any worse than any other site.

Rather it was Microsoft's numerous bugs and vulnerabilities within IE which 
lead people to disable scripting. And of course annoying pop-up windows are 
another major reason to disable javascript.

Konqueror is the only browser (that I've used) which supports per-site 
javascript policy (deny, allow, disable pop-ups).

 IMO, it's now like targetting only websafe colors because some people
 might only browse in 256 colors.  If they do that, about 80% of the
 web's content will look like crap anyway, and they won't specifically
 think my stuff looks all that much worse than anyone else's.

You're comparing apples with spades. I think with most browsers, people need 
to make a conscious decision to disable javascript (ie it's enabled by 
default). In other words these people /should/ know what they're doing by 
disabling it.

On the other hand I don't think many people would actively choose to browse 
in 256 colours when any machine less than 3 years old would most definitely 
support true colour.

You yourself have already outlined how to do it:

  drop the last 'word' (it may be incomplete), using explode(), array_pop()

You may have to refine the process to suit your needs.

Not sure if I understand your problem correctly.

Define your server path as: http://www.myserver.com/some/path  (NB no 
trailing slash)

If the first char of file contains '/' use:

  $server_path$file

otherwise use:

  $server_path/$file

 This would be no problem in Perl or C but I cannot get this to work in PHP.

 I have tried using

Try using fread() to get your file (it's binary safe). Then use:

  explode(chr(0), $buffer);

to separate your fields.

 i.e. if i install kernel-headers 2.4.1 or wahtever is that ok? or will

Here I would assume you're referring to the width of the text. Thus what you

 [10] = 9.00
 [11] = 10.50
 [12] = 11.00
 [13] = 11.26
 [14] = 13.10

 How do I maintain a varible name (for identification) in this output
 list ie:

 onec = 4.90 //from the varible $onec_rounded_total
 cfl = 4.99
 bo = 5.06
 and so on...

First you need to define your array so that it encapsulates some form of 
identification:

  $orderd_list = array ('onec_rounded_total' = $onec_rounded_total,  
'aps_rounded_total'  = $aps_rounded_total, ...);

Then use asort().

 when even after just copying  pasting the code from the tutorial  then
 running it I get an error. I even tried the above using print($fname) but
 without any luck. But if I include the following line in the PHP code
 before the above PHP line

You're probably using a newer of php (4.1.X) in which the default behaviour 
of many aspects of php had changed.

So if you're using php 4.1.X then you need to reference $fname as:

 $_POST['fname']

Or if you had use the GET method in your form then:

 $_GET['fname']

 I've been banging my head against regular expressions all night... help
 would be greatly appreciated.  Could you give me examples on how to do the
 following?

Is this for a programming assignment/exercise? Do you /have/ to use regex? 
Other methods may be easier. I'll do the two simple ones:

 Pull everything except a specific word from a sentence.  For example,
 pulling everything except the word run from the water run was steep.

a) Use str_replace(), search for 'run ' (or ' run') and replace with ''.
b) explode() the string, put 'run' (and any other words you don't want) into 
an array, then use array_diff()

 Pull all words from a string starting with a specific letter or
 pattern.  For example, pulling all of the words starting with the letter r
 from run beep burp ran rin ron runt zoot zip pow

a) explode() the string, loop through array check 1st char of each element.

 I apologize in advance if these are really simple.  It's just that I'm new
 to regular expressions and reading all of the web page tutorials, manual
 pages, and mailing list archive messages has left me thinking I'm
 complicating something somewhere, because it really shouldn't be this hard.

As you can see, a bit of lateral thinking can get you the same results 
without the headbanging. Using regex can be expensive in terms of CPU cycles 
and very often simpler methods will suffice. By all means learn regexes as 
they are damn useful. But start simple then build upon it.

 You don't need to go as far as that.  Just removing the parentheses from
 the original statement would have done the trick -- the commas are fine.

Or keep the parentheses but replace the commas with a period ( , - . ).

Assuming that you do not require a user to logout, there is no reliable

is know (1) When they logged in  (2) When their last request was.

 I've kinda made some login code which basically checks the database
 and then sets a cookie which I think I will change cause it looks like I
 wonna do session variables. Anways anyone either know of a decent
 authentication lib that I can use to check the users online and do
 authentication or can someone point me in the right direction in doing
 this?

There's something called php_lib_login that you can google for.

But the flaw in that is if the nasty user was determined, there's nothing to 
stop them from:

1) looking at the source of the legitimate page
2) grabbing the 'hidden' value
3) creating their own form along with that hidden value
4) opening a new window
5) loading their own form and submit away.

With php you can do all that using a single page. Rough outline:

if (no form data submitted) {

else if (not confirm) {

 Here is the header info being used...

M$ Excel is not a browser (not yet anyway, and hopefully it doesn't evolve
