What I would do is something like this (assuming your table has a column 'filename' in it): Create a cron job (on windows, I think the command is called 'at'?) that runs this query select filename from photo_table order by rand() limit 1 once per day, then copies that file to a predefined location (eg images/pic_of_the_day.jpg). Then, your web page simply refers to images/pic_of_the_day.jpg. The contents of pic_of_the_day.jpg change every time the cronjob runs (unless you randomly pick the same picture twice; not likely with 1000 rows, but you could include some sort of flag [eg; last used date] to avoid picking the same image twice, or to cycle through all images before reusing them). This requires one database hit per day, returning one row, so the load is next to nothing. The cronjob could be written in any language, but since this is a PHP list you'll have to promise to write it in PHP ;) steve -- +--- my people are the people of the dessert, ---+ | Steve Edberghttp://pgfsun.ucdavis.edu/ | | UC Davis Genome Center[EMAIL PROTECTED] | | Bioinformatics programming/database/sysadmin (530)754-9127 | + said t e lawrence, picking up his fork + -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

The only remedy agaonst remote linking is to embed some kind of
expiration in the link that accesses the document. I usually do this
by
using a combination of the document ID, a timestamp, and salt, and md5
or sha1. For instance the following:
?php
$id = 'THE DOCUMENT ID :)';
$now = time();
$salt = 'Some site specific salt.';
$accessId = $id.':'.$now.':'.sha1( $id.':'.$now.':'.$salt );
echo 'a href=/docs/myDocument.php?id='.urlencode( $accessId ).''
.'The Document'
.'/a';
?
Then when someone actually requests the page we do the following:
?php
$salt = 'Some site specific salt.';
$lifespan = 2 * 24 * 60 * 60; // 2 days
if( !($accessId = isset( $_GET['id'] ) ? $_GET['id'] : false) )
{
die( 'No document requested.' );
}
list( $id, $timestamp, $code ) = explode( ':', $accessId );
if( $code !== sha1( $id.':'.$timestamp.':'.$salt ) )
{
die( 'Invalid document request.' );
}
if( (time() - $lifespan) $timestamp )
{
die( 'Document has expired.' );
}
// Otherwise flush document to browser.
?
Now this doesn't stop anyone from saving the document locally but it
does prevent linking to your site and wasting your resources. The
key to
the method is that only you know the $salt and so only you can create
the encoding that validates the passed ID and timestamp. You can also
add more attributes to the encoding such as a user ID. Then you could
ensure the user is logged in, and that the access ID must match their
logged in ID.
Cheers,
Rob.
I'm probably about to show my ignorance here... But by showing it
hopefully, I can learn from it! Wouldn't it be just as effective to
have a salt that gets passed to the script and do something like:
if($salt =Correct salt){
//display correct picture
}else{
//display some random picture of a guy flipping you the bird and echo
out Don't steal my pictures
}
Now that I type that out, I see that it will still use bandwidth which
if you are on a measured plan I could see being a problem.
So I think I just convinced my self that yours is better... Any thing
really wrong with my idea though?

You can't pass the salt, the salt is like a password. If the end user
knows it they could arbitrarily change the document ID or timestamp in
which case access is no longer under your control. This is why we create
a sha1 encoding based on the document ID, the timestamp, and the salt.
If any of the parameters changes we don't get the access code and so we
know that tampering has occurred with the request parameters.
Cheers,
Rob.

[PHP] PHP 5.2.5 Install Question/Problem
OK I have tried e-mailing the PHP-Install mailing list and all I got in response from that list was spam... So I thought I would try here. OK I am attempting to install PHP 5.2.5 on a new system here is what I have: SunOS server1 5.10 Generic_118833-24 sun4u sparc SUNW,Sun-Fire-V210 Here is the GCC version: gcc version 3.4.3 (csl-sol210-3_4-branch+sol_rpath) now when I run the ./configure I am doing a : ./configure --prefix=/opt/local/stow/php-5.2.5 --with-apxs2=/usr/local/httpd-2.2.8/bin/apxs --with-config-file-path=/usr/local/apache/conf Nothing special on that..

[PHP] Another question about functions...
HI everyone,
I think I'm getting closer to understanding functions, but I'm
blanking on how to fix a problem that I have... I am attempting to
export a database to excel, which was working before converting the
code into a function.
What's happening is, I have the code set and it downloads the file
into excel, but it doesn't have the database fields in it, rather a
copy of the entire webpage which it trys to put into excel. Below is
the code that I am using in my function to export the records:
?PHP
function excelexportfunc($select, $sortOrder, $exportdate) {
$export = mysql_query($select);
$fields = mysql_num_fields($export);
for ($i = 0; $i $fields; $i++) {
$header .= mysql_field_name($export, $i) . \t;
}
while($row = mysql_fetch_row($export)) {
$line = '';
foreach($row as $value) {
if ((!isset($value)) or ($value == )) {
$value = \t;
}
else
{
$value = str_replace('', '', $value);
$value = '' . $value . '' . \t;
}
$line .= $value;
}
$data .= trim($line). \n;
}
$data = str_replace(\r, , $data);
if ($data ==) {
$data =\n(0) Records Found!\n;
}
header(Content-type: application/vnd.ms-excel);
header(Content-Disposition: attachment; filename=Export..
$exportdate..xls);
header(Pragma: no-cache);
header(Expires: 0);
print $header\n$data;
}
?
I am calling the function like so: excelexportfunc($select,
$sortOrder, $exportdate);
the $select is specified in an IF statement on the calling page like so:
if($exportoption ==all){
$sortOrder= $_SESSION['order'];
$search = ;
$select = SELECT * FROM .$table. order by .$sortOrder.;
}else{
$sortOrder = $_SESSION['order'];
$search = $_SESSION['search'];
$select = SELECT * FROM .$table. WHERE FName like '%.$search.%'
or LName like '%.$search.%' or Add1 like '%.$search.%' or Add2
like '%.$search.%' or City like '%.$search.%' or State like '%.
$search.%' or Zip like '%.$search.%' or XCode like '%.$search.%'
order by .$sortOrder.;
}
If anyone has any ideas I would love to hear about them. Hopefully
it's just a simple . in the wrong place! :)

if( $code !== sha1( $id.':'.$timestamp.':'.$salt ) )
{
die( 'Invalid document request.' );
}
if( (time() - $lifespan) $timestamp )
{
die( 'Document has expired.' );
}
// Otherwise flush document to browser.
?
Now this doesn't stop anyone from saving the document locally but it
does prevent linking to your site and wasting your resources. The key to
the method is that only you know the $salt and so only you can create
the encoding that validates the passed ID and timestamp. You can also
add more attributes to the encoding such as a user ID. Then you could
ensure the user is logged in, and that the access ID must match their
logged in ID.
Cheers,
Rob.

Btw, apache does a good job of dealing with remote links:
RewriteCond %{HTTP_REFERER} !^https?://jessen.ch/
RewriteRule /images/(.*) http://jessen.ch/no-remote-linking-please?item=$1
It's a rough example, but the idea should be obvious.

theoretically, you could use a stream context and set a notification
handler, however, i was unable to get notifications when using this code:
function httpStreamNotificationHandler($notification_code, $severity,
$message, $message_code, $bytes_transferred, $bytes_max) {
echo __FUNCTION__ . PHP_EOL;
var_dump(func_get_args());
}
$options = array('http' =
array('method' = 'GET',
'timeout' = 3
)
);
$streamContext = stream_context_create($options);
if(stream_context_set_params($streamContext, array('notification',
'httpStreamNotificationHandler'))) {
echo 'stream context parameters set, loading remote resource..' .
PHP_EOL;
// load remote resource
$theFile = file('http://www.remotesite.org/mypage.html', null,
$streamContext);
var_dump($theFile);
} else {
echo 'couldnt set context parameters' . PHP_EOL;

you might also get something out of the timeout option, which i set in the
code above,
but ive not verified its working correctly either.
also, you might try curl.

I'm not exactly sure what you are trying to accomplish or what sort of
access you have to the server, but if it were me I wouldn't rely on a
remote connection in real time. I would have a cron job that
periodically updated the results that I am expecting so that reads on
your site are very fast. Like I said though I'm not sure what you're
using this for so I cannot say whether or not it is okay for you to
cache this data locally for 5 minutes or even 1 day.
If you can cache it but cannot run cron jobs, then just write the
return buffer to a file and hold that for as long as possible checking
the last time it was wrote to see if it needs a refresh.

[PHP] Using next() inside a foreach
Hello,
I'm hesitant to report this issue as a bug, since I see other bugs
(43890 and 43220) already opened describing similar, but not identical,
issues. The latter bug is described as a documentation issue...
In my tests all versions of php prior to 5.2.4, foreach does NOT
increment the array pointer for each iteration, at least not at the top
of the loop. This new behavior in 5.2.4 breaks array look-ahead logic,
when using next() -- since you end up looking TWO places ahead instead
of one.
This produces the effect that in the body of the loop, current()
actually returns the next value in the array -- which is the
workaround I've implemented in my code for doing a look-ahead -- though
it seems non-intuitive to have current() return the next value.
Perhaps the previous behavior was to increment the array pointer at the
END of the foreach block, and now for some reason it's incrementing it
at the BEGINNING? That would explain it I guess...
Perhaps there's a better way to do look-ahead, but for a behavior change
like this, if it's intentional, shouldn't it at least be in the
Backward Compatibility section of the migration docs?
Example Code:
$test_arr = array('zero', 'one','two','three','four');
foreach ($test_arr as $idx = $val) {
$next_val = next($test_arr);
print This: . $idx . - . $val . \n;
print Next: . $next_val . \n;
}
-
output under v5.2.3 (and 4.4.8):
-
This: 0 - zero
Next: one
This: 1 - one
Next: two
This: 2 - two
Next: three
This: 3 - three
Next: four
This: 4 - four
Next:
---
output under v5.2.4 and v5.2.5:

This: 0 - zero
Next: two
This: 1 - one

im guessing youre trying to hit the invocation of excelexportfunc(), as
it sits in your existing script. create a simple test script that does
nothing
else but invoke the excelexportfunc() function. you can pass variables to
it from the url, or hardcode them if you like; id probly hardcode them at

?php
include('excelexportfunc.php'); // -- set accordingly
$select = ''; // -- set me
$sortOrder = '' -- set me
$exportdate = '' -- set me
excelexportfunc($select, $sortOrder, $exportdate);
?
that *should* get you the results youre looking for. from there you need to
determine why the method isnt working in the context of your existing
script.

Bob is a class, not a method. You could try this:
?php
$obj = new Bob();
$obj-getBlah();
?
It's not method chaining though.

Actually, I don't think so. I believe constructors return void, while
the 'new' keyword returns a copy of the object.
im pretty sure constructors return an object instance:
php class Test { function __construct() {} }
php var_dump(new Test());
object(Test)#1 (0) {
}
but anyway, how could you even test that __construct() returned void
and the new keyword returned a copy of the object? new essentially
invokes __construct() and passes along its return value, near as i can tell.
Christoph,
if you dont want to write a function in the global namespace, as suggested
in the article, Eric posted, just add a simple factory method in your class,
eg.
?php
class Test {
public static function getInstance() {
return new Test();
}
public function doSomething() {
echo __METHOD__ . PHP_EOL;
}
}
Test::getInstance()-doSomething();
?

you can't chain of the constructor as Andrew explained.
you may wish to return object clones to chain with as opposed to
the same object - the example below is fairly bogus but it
mgiht be helpful to you (btw run the code to see what it actually
does as opposed to what you think it should do ... hey it caught
me out and I wrote it!):

function triple() { $this-x *= 3; return clone $this; }
function output() { echo $this-x, \n; }

its an esthetic thing; and besides the simple factory method is an
easy workaround to achieve it.
as the article that, Eric, posted mentioned, other languages have
such support; ie javascript:
function Test() {}
Test.prototype = { doSomething : function() { alert('hello'); } }
new Test().doSomething();
this is along the lines of the whole returnAnArray()['someIndex'] thing,
fortunately in this case, theres a workaround in userspace ;)

dunno can't see you. but your class looks like crap, in fact it don't think it
will even parse. have you tried running it?
?php

public $connInfo[$database] = 'db23499_donors';
the above is plain wrong.
1. you can't do multiple property definitions for a single [array] property
2. your storing hardcoded values in a class which is meant to be somewhat
generic/reusable
3. you've just told the world your password/login/db credentials
public __construct() {
return $this-$connInfo;
}
constructors aren't meant to return anything. besides you won't be able to
retrieve the returned value.
not too mention '$this-$connInfo' is the wrong syntax it should be:
$this-connInfo
I'd recommend some more research on basic class syntax.

im guessing youre trying to hit the invocation of excelexportfunc(),
as
it sits in your existing script. create a simple test script that
does nothing
else but invoke the excelexportfunc() function. you can pass
variables to
it from the url, or hardcode them if you like; id probly hardcode
them at first.
?php
include('excelexportfunc.php'); // -- set accordingly
$select = ''; // -- set me
$sortOrder = '' -- set me
$exportdate = '' -- set me
excelexportfunc($select, $sortOrder, $exportdate);

that *should* get you the results youre looking for. from there you
need to
determine why the method isnt working in the context of your
existing script.

And it's not really good OO, either. Saying that dbconn extends
dbconfig is saying that a database connection IS-A database
configuration. It isn't. You might say that a database connection
HAS-A database configuration. Actually, your code says that a
database connection IS-A database configuration that HAS-A database
configuration since dbconfig is both a member property and a parent
class of dbconn. And, as pointed out on your other thread, the
dbconfig constructor should not even have a return statement.
I'm definitely no OO expert, but it looks like you are trying to use
OOP simply because you can, even though you don't seem to understand
how objects can/should relate to one another.

[PHP] Timeout while waiting for a server-client transfer to start (large files)
Hey
I have a script that I am trying to figure out to allow a remote file to
be sent to a client's browser. It works ok for small files, but it keeps
timing out for large files. I don't think it should even take as long as
it does (i.e. about 10seconds) before it pops up a dialog box for me to
download a 700KB file. Any ideas? It times out on a line around which reads
while (!feof($fp))
{

Re: [PHP] Using next() inside a foreach
Erik Stackhouse wrote:
Hello,
I'm hesitant to report this issue as a bug, since I see other bugs
(43890 and 43220) already opened describing similar, but not identical,
issues. The latter bug is described as a documentation issue...
In my tests all versions of php prior to 5.2.4, foreach does NOT
increment the array pointer for each iteration, at least not at the top
of the loop. This new behavior in 5.2.4 breaks array look-ahead logic,
when using next() -- since you end up looking TWO places ahead instead
of one.
This produces the effect that in the body of the loop, current()
actually returns the next value in the array -- which is the
workaround I've implemented in my code for doing a look-ahead -- though
it seems non-intuitive to have current() return the next value.
Perhaps the previous behavior was to increment the array pointer at the
END of the foreach block, and now for some reason it's incrementing it
at the BEGINNING? That would explain it I guess...
Perhaps there's a better way to do look-ahead, but for a behavior change
like this, if it's intentional, shouldn't it at least be in the
Backward Compatibility section of the migration docs?
Check out the second NOTE on the foreach page:
http://us2.php.net/foreach
Note: Unless the array is referenced, foreach operates on a copy of the
specified array and not the array itself. foreach has some side effects on the
array pointer. Don't rely on the array pointer during or after the foreach
without resetting it.
if you are running next() or current() on the $test_arr below, you are not
accessing the same array that is being used in the foreach loop. Foreach is
using a copy of the $test_arr array().
Example Code:
$test_arr = array('zero', 'one','two','three','four');
foreach ($test_arr as $idx = $val) {
$next_val = next($test_arr);
print This: . $idx . - . $val . \n;
print Next: . $next_val . \n;
}
-
output under v5.2.3 (and 4.4.8):
-
This: 0 - zero
Next: one
This: 1 - one
Next: two
This: 2 - two
Next: three
This: 3 - three
Next: four
This: 4 - four
Next:
---
output under v5.2.4 and v5.2.5:

this is along the lines of the whole returnAnArray()['someIndex']

fortunately in this case, theres a workaround in userspace ;)
I don't see how it's any more aesthetically pleasing, but each to

Personally I'd use a static method in this instance. If you need to
create an instance of the class you can do so in the static method and
that way it will get destroyed when the function is done. Otherwise
the object scope is far larger than it needs to be, which IMHO is an
unnecessary waste of resources and certainly less aesthetic.

[PHP] potentially __sleep() bug
all,
i was playing around w/ some object serialization tonight during
further exploration of spl and i stumbled on what appears to be a
bug in the behavior of the __sleep() magic method.
here is the pertinent documentation on the method
..is supposed to return an array with the names of all variables
of that object that should be serialized.
so, the idea is, *only* the instance variables identified in the array
returned are marked for serialization.
however, it appears all instance variables are being serialized no matter what.
see the reproducible code below. ive run this on 2 separate php5
boxes, one w/ 5.2.5, another w/ a 5.2.something..
?php
class A {
public $a1 = 'a1';
public $a2 = 'a2';
public $a3 = 'a3';
public function __sleep() {
echo __FUNCTION__ . PHP_EOL;
return array('a1', 'a2');
}
}
var_dump(unserialize(serialize(new A(;
?
this is what i get despite having marked only member variables 'a',
and 'b' for serialization.
__sleep
object(A)#1 (3) {
[a1]=
string(2) a1
[a2]=
string(2) a2
[a3]=
string(2) a3
}
consensus ?

Re: [PHP] Another question about functions...
What's happening is, I have the code set and it downloads the file into
excel, but it doesn't have the database fields in it, rather a copy of
the entire webpage which it trys to put into excel. Below is the code
that I am using in my function to export the records:
?PHP
function excelexportfunc($select, $sortOrder, $exportdate) {
echo $select . br/\n;
if you run that through your db manually do you get an error?
$export = mysql_query($select);
var_dump($export);
$fields = mysql_num_fields($export);
// initialize the header line to be an empty string.
$header = '';
for ($i = 0; $i $fields; $i++) {
$header .= mysql_field_name($export, $i) . \t;
}
You will need a trim here otherwise you'll have an extra empty column
(extra \t in there):
$header = trim($header);
while($row = mysql_fetch_row($export)) {
$line = '';
foreach($row as $value) {
if ((!isset($value)) or ($value == )) {
$value = \t;
}
else
{
$value = str_replace('', '', $value);
$value = '' . $value . '' . \t;
}
$line .= $value;
}
$data .= trim($line). \n;
}
$data = str_replace(\r, , $data);
if ($data ==) {
$data =\n(0) Records Found!\n;
}
header(Content-type: application/vnd.ms-excel);
header(Content-Disposition: attachment;
filename=Export..$exportdate..xls);
header(Pragma: no-cache);
header(Expires: 0);
print $header\n$data;
Once you've printed out the report, you should probably exit so nothing
else is processed from the script.
}
?
I am calling the function like so: excelexportfunc($select, $sortOrder,
$exportdate);
the $select is specified in an IF statement on the calling page like so:
if($exportoption ==all){
$sortOrder= $_SESSION['order'];
$search = ;
$select = SELECT * FROM .$table. order by .$sortOrder.;
}else{
$sortOrder = $_SESSION['order'];
$search = $_SESSION['search'];
$select = SELECT * FROM .$table. WHERE FName like
'%.$search.%' or LName like '%.$search.%' or Add1 like
'%.$search.%' or Add2 like '%.$search.%' or City like
'%.$search.%' or State like '%.$search.%' or Zip like
'%.$search.%' or XCode like '%.$search.%' order by .$sortOrder.;
}
$sortOrder is now part of $select you don't need to pass it to the
function unless you actually use it in that function (which from your
copy/paste isn't the case).
So your function can just be:
function excelexportfunc($select, $exportdate) {
and remove the $sortOrder from the calling lines:
excelexportfunc($select, $exportdate);

[PHP] Sum of results
Hi;
I've tried Googling this out but failed to search for an answer to this, so
I'm posting to this list. I'd like to know if there's a way to get the sum
this results:
// Results
Individual Daily Consumption
//AccountNo : Consumption
4146121002: 1.42
4146111002: 0.29
4146113002: 1.38
4146110002: 0.33
4146112002: 0.00
4146118002: 9.96
== MORE ==
// Code that generated the results
while ($row6 = mysql_fetch_assoc($queryconsumerresults)) {
// Show Consumer AccountNo and their Consumption
echo $row6['AccountNo'] . : . sprintf(%1.2f, $row6['Reading']
+
$row6['KwHrAdjustment']) - ($row6['Reading1'] + $row6['KwHrAdjustment1'])) /
$noofdays) * $row6['Multiplier'])) . br /;
}
I've tried getting the sum() from the MySQL table, but Multiplier is either at
1 or 2 or 2.5 and the only way I can get an accurate total consumption is
getting the sum from the results.
Is there a way I can place this code on an array? I've tried using
$indcons = array( sprintf(%1.2f, $row6['Reading'] + $row6
['KwHrAdjustment']) - ($row6['Reading1'] + $row6['KwHrAdjustment1'])) /
$noofdays) * $row6['Multiplier']))) but I've obviously failed.

Well you're still reading the file (or url or something) at this point.
Is it the reading of the file or sending it to the browser that fails?
A bit of context might help for this code too. Is this reading a local
file or url or what?
If it's a local file, use fpassthru (http://php.net/fpassthru) if it's
not too big. If it is a big file then use your loop but don't store it
in a $tmp variable, just output it.

array() creates an array, what youve done on this line is created
an array with one element, which will be the last value of $row6 from the while
loop that precedes it. since the last value returned from mysql_fetch_assoc()
is false (thats what terminates the while loop), im guessing $indcons contains
false as its only value.
if you want to place these values in an array as you iterate over them, add this
inside the while loop:
$indcons[] = $curVal;
