Just grap the lastest stable version.  As of now:

Apache ver 1.3.22
PHP    ver 4.0.6

Most all of my Sparc Solaris8 machines are running Apache 1.3.19/PHP 4.0.6

Hope this helps.

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...

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.

Nice tip!  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>.

Thanks guys

I just want to confirm one last thing, as it's been a while since I needed 
cron

After I create this file (cron.file) for ex
and use 
crontab cronfile (I do this as root, if it matters)
do permissions need to be set? I really can't recall
I would think that would do it as I am not uploading it
and do it as root 

Thanks for the help, GREAT help and it's appreciated

Now I just need to get freetype 2 installed right on my raq 3
and I can live like a king

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.

Thanks for the code!  The easiest way for me personally to learn a new 
language is to think of a task that needs to be done then look at some 
sample code.  I'm not quite ready to learn Python (yet) but I'm saving this 
into the archive for when I'm ready. :)

    I need to "convert" the following:

---------------------------------------------------

  Instruction:
---------------------------------------------------

    ...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.

OK, I took a stab at this using your post for input and it should be a
good enough starting point for you ... if you do have extraneous ':'s
elsewhere in the message then you'll need to be a little more picky with
your regex stuff to only pick out what you want -- for example, your
post has a couple of sentences that end with ':' before an example ...
the script as written picks those up as key value pairs, but since
you'll unlikely have those in your order messages I figure you're on
safe ground for now --

Of course the really easy way to do this is just to process the form
output directly then you have your key/values nice and neat in
$HTTP_POST_VARS already:) ... but I'm assuming this is on and processed
by a separate server, or with a canned script that only gens emails, so
this is what you need to do.

Here's the code:


#!/usr/bin/php4 -q
<?
// OK, I assume you use this as a filter, so we're reading from
// php://stdin --
$fp = fopen("php://stdin","r");

// Initialize a counter for the order items
$itemcnt=0;

while(!feof($fp)) {
        $buffer = fgets($fp,8192);
        // Simple regex effectively 'splitting' on colon(:) with capture
        if(preg_match('/([^:]+):\t*(.*)/',$buffer,$matches)) {
                // strip out spaces and /'s in the variable name
                $matches[1] = preg_replace("/[ \/\"]/","",$matches[1]);
                // create an entry for it in $billinginfo array
                $billinginfo[$matches[1]] = $matches[2];
                }
        // Regex to match order items (INCOMPLETE!!!) only matches order
        // number and quantity so far -- Hey I had to leave something for you
        // to do:)
        if(preg_match('/([0-9]+x[0-9.]+)\s+([0-9]+).*/',$buffer,$orderitem)) {
                // since we don't have field ids in the matches, we create our own
                $order[$itemcnt]["Itemnum"] = $orderitem[1];
                $order[$itemcnt++]["Quantity"] = $orderitem[2];
                }
        }
fclose($fp);

// just for testing, dump the arrays --
while(list($key,$val) = each($billinginfo)) {
        echo "$key -> $val \n";
        }
echo "ORDER HERE!!!\n";
for($x=0; $x<$itemcnt; $x++) {
        echo "Item: $x \n";
        while(list($k,$v) = each($order[$x])) {
                echo "$k -> $v \n";
                }
        echo "\n";
        }
?>

Hi,

To test a new php installation I accessed a page called index.php that
contains only <?php phpinfo(); ?> but that produces this error:

Warning: Failed opening '' for inclusion
(include_path='.:/usr/local/lib/php:/usr/local/include/php:/usr/local/bin/ph
p') in Unknown on line 0

This seems very odd given that:

a) the error does not specify any filename that failed opening, only '', and

b) permissions of the index.php file and the include path directories are
readable by all users.

I have even started the php fastcgi runner as root to double-check the
permissions aspect of this. The setup is php 4.0.6 with Zeus webserver
version 4 using FastCGI on Solaris 2.6.

Any ideas? Help of any sort would be greatly appreciated.

Thanks,

Dave De Graff

Perhaps you want to:
<?phpinfo();?>

Not sure if anything else should produce errors..

Hi

Can anyone explain classes to me please? On many sites have I seen classes,
I'm not sure how these work, or how to use them. I'm still learning about
php, and I get it going nicely. Is a class something like a variable (but as
a whole script) that I simply include into my other scripts?
Your help would be grateful as I'm still learning, and all info or knowledge
helps

Regards

Rudi Ahlers

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...

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...

Yeah, use a real client program like Terra Term.

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

Hi,

is there a way to redirect after a script has run?

I have a form whos result is being put into a database. When, or if, the
operation is sucessful i set a variable $done to 1.

Now, i need a redirection from here (if $done is 1). But since i cant send
out headers that far down on the page - what do i do?

Regards

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.
