It sure can. There's a couple of ways to accomplish this. I personally think the easiest way is to code your page like normal, then call it in a cron job via lynx. Let's say you have a page called "page.php" that connects to your database, retrieves the email addresses, and sends the emails. To call it from a cron job add the following to your crontab: 0 8 * * * /usr/bin/lynx -dump http://localhost/page.php > /path/to/logfile/or/dev/null Of course this means your script is in your public web space, so theoretically could be called by anyone who knew the name of the page. You could put the page in a subdirectory and add an .htaccess file that restricts access to only 127.0.0.1 to take care of that if it concerns you. If you have PHP installed as a CGI then you could also write your page as a shell script. As the first line of your script put the line: #!<path to php> -q I haven't personally used this method because I have PHP installed as an apache module and I was too lazy to compile the CGI version. Using lynx in the above configuration works fine for me...--- End Message ---
--- Begin Message ---If you have built the php standalone binary then its easy- #!/usr/local/bin/php <?php // your php code here ?> What I do when I build php is build it twice. First I build it with all my options EXCEPT for with-apxs=/blah That builds the standalone binary, and I install that in /usr/local/bin Then, I build the apache module and install that where my apache modules go. This allows me to use php as a regular unix scripting language, so I can do stuff from the crontab. btw- I'm actually doing a very similar thing- I have some customer support software that pops my support e-mail address and puts the message in a MySQL database. I have a cron job that calls a php shell script that pops the e-mail for me every 15 minutes. That way I don't have to log on to the support application as often, and the customers get an automated response fairly quickly, giving them a unique case ID etc. On Sat, 24 Nov 2001 22:04:21 EST [EMAIL PROTECTED] mentioned: > Thanks for your time . *This* = create follow up autoresponders > Or at least have php run with cron, so I can daily hit a mysql > db and use php to email those people at a specified time, like > every 3 days.

Another alternative is using wget on the URL, or links -dump if you have that instead. Or if your script has #!/usr/bin/php or whatever path at the top and is made executable, you can just call that script without relying on the webserver. I think, even if it's just a normal php file you could cron it as /usr/bin/php <scriptpath/name>. -- Casey Allen Shobe [EMAIL PROTECTED] GCS/CM d+ s+:->+: a-- C++(++++) ULU++++$ P- L+++>++++ E- W++ N++ !o K- w-- !O M V- PS++ PE Y+ PGP>++ t+ 5+ X R>+ tv-- b++ DI+ D---- G++ e h-(*) r--- z----- End Message ---

I've followed this with interest, but unless you specifically need some
properties of PHP to do this, use an easier tool.
Python has modules for both MySQL and PHP. They are easily invoked and
don't involve calling Lynx & feeding it the script.
Here's some code, you might want to think about it as an alternative. I
hope the indents preserve, as Python reliese on indentation and a <CR> ends
it's line.

...into $key, $value pairs. Ideally, I'd like to be able to name/use my own names
for $key so I can end up with something like:
$BillToContact => 'Ashley M. Kirchner'
$BillToDayPhone => '800 555-1212'
$BillToEvePhone => '303 555-1212'
etc.
(or maybe with something like:
$bill['contact'] => 'Ashley M. Kirchner'
$bill['dayphone'] => '800 555-1212'
$bill['evephone'] => '303 555-1212'
etc.)
All of these variables will eventually be shoved into a DB once the entire form
has been parsed.
And then, at the bottom of that same (submitted) form, there's the actual
information on the order, which looks something like this (the spacing is slightly
different):
(unfortunately, this will wrap rather ugly)
---------------------------------------------------
ORDER NO. QTY UNIT DESCRIPTION PRICE TOTAL
4x6 1 4"x6" Standard Print (full-frame from 35mm) .75 $0.75
4x6 1 4"x6" Standard Print (full-frame from 35mm) .75 $0.75
5x7.5 1 5x7.5 Image:Uploaded Image 3 4.25 $4.25
8x12 1 8x12 Classic Full Frame Image:Uploaded Image 4 10.25 $10.25
SUBTOTAL: $16.00
TAX: $1.18
SHIPPING: $0.00
TOTAL: $17.18
---------------------------------------------------
This part again I'd like to break up into separate lines, and separate variables
for the product no., the quantity, unit, decription, price, total (per line), then the
subtotal, tax, shipping cost and final (grant) total.
Again, if I can somehow use my own variable names, that'd be great.
($product['no']
$product['quantity']
$product['unit']
etc.
$order['subtotal']
$order['tax']
$order['shipping']
$order['total']
etc.)
I don't know yet how to create different entries for each line in that order -
kinda stupid to create $product_1['no'], $product_2['no'], $product_3['no'],
$product_4['no'], but then again, I don't know.

There are people earning PHD's while explaining classes. I know your
question originates from using PHP, and this is a PHP general mailing list
... but your question is just a tad too general for this list.
> I'm not sure how these work, or how to use them. I'm still learning about
Classes aren't unique to PHP. You need to learn a true object-oriented
programming language (C++, Java, ... etc.) to really learn classes.
Truly gifted individuals can learn object-oriented programming w/o too
much help, but they'd first have a firm grip on programming. I'd expect
the average, novice programmer to need a good amount of help learning &
understanding objecte-oriented programming ... like that attained from a
University, a good High School, or a lot of independent study and time
experimenting with code.
That said ...
You weren't completely missing the boat with your analogy of a class to a
variable, but in the same breath, that idea is totally missing the boat (I
can see from where you're coming, and to where you're headed). Classes
are an IDEA. They're not actually anything. They're the definition of
private and public data members and methods that should make up an object.
When a class is instantiated, an object is created with the defined data
members and methods available. You can then use the objects' methods to
set, get, alter, or otherwise interact with its data members, or to simply
perform a set of related operations. <Insert a couple semesters of theory
here.> That's my feeble attempt to explain classes. It's abstract, I
know, and possibly not a help at all. But it's because of the paragraph
above this one.
Let's look at some petty code:
class chair{
// DATA
var num_legs;
var color;
var num_arms;
// METHODS
function chair( $legs = 3, $arms = 0 ){ //CONSTRUCTOR
$this->num_legs = $legs;
$this->num_arms = $arms;
}
function setLegs( $legs ){
$this->num_legs = $legs;
return;
}
function getLegs( ){
return $this->num_legs;
}
// ... *clip* ...
}
Above is the [incomplete] definition of a chair class. As you can see,
the class is useless. But you can instantiate the class, and create a
useable object ... you can now create a chair.
$myChair = new chair( 4, 2 );
Now I have a chair [object] with 4 legs and 2 arms, called $myChair.
Let's have the chair tell us how many legs it has ...
$numLegsOnMyChair = $myChair->getLegs();
print( "My Chair has $numLegsOnMyChair legs." );
Lets change how many legs the chair has ...
$myChair->setLegs( 7 ); // very odd, seven-legged chair
We should have a chair with 7 legs now, instead of 4. Prove it ...
$numLegsOnMyChair = $myChair->getLegs();
print( "My Chair has $numLegsOnMyChair legs." );
(As you alluded to previously, the object $myChair is seemingly a variable
that has access to scripts ... but I hope you see now that $myChair is an
object with methods and data members, not a variable.)
That's very simple, and not too useful. Which brings me to the next
point. Knowing object-oriented programming is to know when and when not
to use it (especially with PHP). I don't need a class definition and an
object for a one-time use 7-legged chair. But I may need a class
definition if I were making many complete graph data structures, each with
a number of nodes equal to a unique number in the Fibonacci sequence. I
wouldn't want to re-code the basic logic of a complete graph over and over
for each graph. I could just instantiate graph objects, each with
different numbers of nodes, much like I did with the chair, above.

Chris,
Not such a useless explanation at all, in fact a damned good one. Tight &
concise, and you immediately related the functions to code examples, along
with an easy-to-visualize object, the chair.
But I have two questions:
1. Why is a constructor class needed? My OO background is Visual FoxPro,
and all it requires is a declaration of the class, it' methods and properties.
2. Are the chairs properties exposed, or are they private? You use
functions to both set and retrieve them, which implies that they are
private. Even so, PHP's syntax is much cleaner than the tortured syntax
used in VB.

Miles,
I have come from a QBASIC to VFP to VC++ to PHP (VFP and PHP are my primary
languages), so I'll try to clear it up a bit.
In VFP, there is no constructor. I believe that the equivalent is the
init() method. The init() method, or the constructor (in PHP, C++, etc)
are useful for doing stuff that needs to be done when an object is
created. Likewise in true object oriented languages (PHP is not one of
them yet), there is a Destructor that is called when an object goes out of
scope or is deleted. In VFP, there is a Destroy() method to simulate this
behavior.
In VFP, there is the notion of Public, Private, and Hidden properties. PHP
does not yet support this behavior. In PHP, especially since it is such a
loosely typed language, you can add and remove properties on the
fly. Generally when programming in PHP, I like to identify private
properties and methods by placing a single underscore before their
name. This makes it clear for someone using the class not to ever
reference these entities.
If you want to see a neat example of object oriented programming in action
(not that I like M$ or anything), check out how the Microsoft Foundation
Classes (MFC) work. They effectively demonstrate public and private class
members, inheritance, constructors, destructors, parent objects, etc...
Hope it Helped...

I am trying to use php and gnupg on my virtual host to send user input to
myself in encryptd form. The problem I am having is that I have installed
gnupg in my user account and it is functional, but the keyring and keys that
I have generated are under my user name for the account. Php runs under the
user name "nobody" and does not have access to the keys for encryption. I
have spoken to a tech at the company who said that I would not be allowed to
install keys under "nobody". I'm not quite sure I believe this.
Anyway, as a way to get around this, I have tried to run the php script as
cgi, by putting the script into the cgi-bin in my user directory. This way
the scripts should run as my username. Here is the script:
#!/usr/local/bin/php
$filename = "/home/gildedpg/public_html/mydata.txt";
$newfile = fopen($filename, "w+") or die("Couldn't create file.");
fclose($newfile);
$msg = "<p>File created!</p>";
<html>
<head>
<title></title>
</head>
<body>
<? echo "$msg"; ?>
</body>
</html>
This is the error I get:
CGIwrap Error: System Error: execv() failed
Error: No such file or directory (2)
If anyone could tell me why this script will not run, or better yet, make any
suggestions to make this process workwithout using cgi, I would appreciate it.
Thanks,
SW

--- Begin Message ---What scenario do you have? 1. User fills in a form somewhere & those values get transmitted to another script which processes them or 2. User fills in a form, clicks "submit" which calls the same script, passing itself the values. Depending on the value passed by the submit button, the script processes the information (INSERT or UPDATE) and sets $done = 1 if successful. The second scenario is easier to handle. Call the same script, passing it $done, and depending on whether or not $done is set you redirect. Juli Meloni has done an excellent tutorial on just this at http://www.thickbook.com. look in the tutorials for something like "Form With Error Message". You just have to adapt the logic to suit your needs.
