Did you have a link for this 'compiler' ? All I see in the site menu
is a link to the encoder. Sorry if I'm just not seeing it.

Hello,
on 05/17/2005 11:27 AM Brian Dunning said the following:
My background is mostly with Lasso. One cool feature is the ability to
make "LassoApps" - single file applications that are secure and can be
sold & distributed without providing access to the source. Does PHP
offer any such capability?
You may want to try this class that generates a PHP script that self
installs packages with many application files.
http://www.phpclasses.org/php2install
Then you can use a PHP compiler like RoadSend to generate executable
binaries to protect the code.

He probably meant the encoder.
Zend has a lot of products, though, and there maybe might be one designed
just to secure your PHP source... I kinda lost track lately, with all the
options out there.
Err, anyway, I just really wanted to say that virtually every Zend product
has been so routinely mis-represented by what it does that the amount of
mis-information out there is probably larger than the amount of correct
info.
Read Zend's website product descriptions first, and ignore forum/mailing
list comments until you're clear on what the product does, and doesn't do.
That will help you separate the patent falsehoods from useful info, and
winnow down your reading by a factor of 3.

Did you try building any complex data structures? You could have whipped
out something to test pretty quickly. The quick answer is, 'Yes'.
The longer answer is: cut-and-past the following into a script and see
what you get:
$cds = array(
'element1' => array(
'string1',
'string2',
'string3'
),
'element2' => true,
'element3' => array(
'subelement1' => array(
array(1, 2, 3),
2,
3
)
)
);
var_dump($cds);
You can create any complexity you want using nested arrays. Arrays in
PHP are ordered (also called indexed) unless string keys are used (in
which case they're called associative) -- and you can mix and match
styles as needed.
Additionally, you can use these structures within objects, and define
object properties on the fly.
Read through the manual about variable types if you need more
information -- and don't be afraid to experiment.

thx 4 various answers
which also lead me to

I seem to remember from a previous life that you can operate directly on PHP
data, I mean you don't
have to use the PHP primitives.

You should see a message from your browser that data is being reposted.

I looked for such a message and the only thing I can find is as follows:
1) _SERVER['HTTP_ACCEPT'] and _ENV['HTTP_ACCEPT'] and change to "*/*", but I
don't know if that is the case for all browsers, do you know?
2) _SERVER['REDIRECT_UNIQUE_ID'] and _ENV['REDIRECT_UNIQUE_ID'],
_SERVER['REMOTE_PORT'] and _ENV['REMOTE_PORT'], _SERVER['UNIQUE_ID'] and
_ENV['UNIQUE_ID'] change, but I don't think the values are predictable,
especially between browsers.
Do you know of a specific message to look for and is that message the same
for all browsers?
--- End Message ---
--- Begin Message ---
As a last resort, I may have to do that, but that is by no means the
preferred method. I want to keep database access to a minimum.
I thought by this time this problem would have had a standard solution. It
would be nice if PHP had a function like refreshed() so one could do ... if
(!refreshed()) { ... } ..., but I guess not.
Thanks for your input.

Robert

The used MD5 hash tells you they are re-submitting the exact same form.
Now, if the real problem is that the user has a fresh new form, and fills
in the same data again by hand, then there are only two possibilities:
1. In the real world, they actually NEED two of the "same" thing in the
database, and your application should allow it.
2. In the real world, users are likely to lose track of where they are in
their data entry, and you need to provide them the context to help avoid
that. When you go back to 1) present a message like "added blah blah blah"
at the top of the screen. Now they *KNOW* they just did blah blah blah,
and can move on to blah blah bleh. Data entry is a sucky job. Make it
nicer for them, eh? You STILL need to code for the dual entry, and do
something intelligent when they mess up, but you can improve efficiency
and decrease errors (where 2 not-quite-the-same-but-really-are-the-same
entries pass your tests) if you make your application nicer to the user.

It appears that your overall problem is a misunderstanding of how arrays
work in PHP and how easy it is to manipulate them.
First:

In general, for practical purposes (if PHP is installed using the
recommended default setup, ie register_globals disabled),
session_is_registered() is deprecated and should not be used. Use:
if (isset($_SESSION['ses_basket_items'])) { ... };
Second:

You seem to be using multiple single dimension arrays to store your basket
details. That is not the optimal way of doing things. You should have a
*single* multi dimension array, there are many ways to do this, here's a
couple:
1)
$basket[1] = array('name' => 'name of product',
'id' => 'product id',
'price' => 'price of product',
'amount' => 'quantity required');
$basket[2] = array('name' => 'name of product',
'id' => 'product id',
'price' => 'price of product',
'amount' => 'quantity required');
2)
$basket['a_product_id'] = array('name' => 'name of product',
'price' => 'price of product',
'amount' => 'quantity required');
$basket['another_product_id'] = array('name' => 'name of product',
'price' => 'price of product',
'amount' => 'quantity required');
OK, so how do you operate on them? In the examples below 2 forms will be
given corresponding to how you defined the arrays as per above.
To remove an item:
1) unset($basket[n]); // where n is an integer
2) unset($basket['product_id']; // if product_id is an integer
// then you don't need the single-quotes
// note that also applies when first
// define the array, ie:
// $basket[product_id] = array(...);
To change an attribute, eg the amount:
1) $basket[n]['amount'] = 5;
2) $basket['product_id'] = 10;
To display an attribute, eg price:
1) echo $basket[n]['price'];
2) echo $basket['product_id']['price'];
When playing around with arrays, print_r() is your friend, use it
liberally.

Jason,
Thx. Even though I have what I need for the client (I finally got things
to work as desired), I'll rework it and update the client version.
I knew I was doing things poorly and it degenerated into simply "get the
damn thing to work."
Thx, Mayo

I have a script which send emails using mail() function. I have 100 email
addresses and i set up the script to send 1 email every 10 seconds. So, it will
take 1000 seconds
to send all 100 emails.
My question is: If I stop the script after,let's say 12 seconds, it will send
only 1 email or all 100?I mean it is possible that the server to cache all
emails and send them if i stop the script? I must say that the script is run
through a web browser.
Thanks in advance for your help !!!!

If you stop the script before PHP executes the instruction to send the
email, then the email ain't gonna go out. Period.
Your best bet would be to use PHP to QUEUE the emails up, and let your
mail sending software (sendmail, qmail, elvenmail) worry about load and
timing.
You may also want to consider having the web-based application simply set
a flag/indicator somewhere which tells PHP that it's time to queue up all
100 emails. Then the end user won't even have to wait for 100 emails to
get queued up in line. They only have to wait for the flag to get set
which should take, like, less than one second.
There are also innumerable PHP mail classes "out there" to make sending
email easier. http://phpclasses.org has some, I'm betting PEAR has some,
and you could Google and find a thousand more.

Hi,
Tonight I installed a new php5 instance.
php5.0.4/apache-1.3.33/mysql-4.1.10. I was getting "\Wed May 18 01:59:42
2005] [notice] child pid 1621 exit signal Segmentation fault (11)" error
whenever I accessed a PHP enable page. I recompiled a few times and
removed unnecessary modules. Still the same problem. So in order to get
a debug output, I recompiled with --enable-debug. The curious thing is,
now the error doesn't occur. Anyone any ideas?
Dave.

Yikes,
Who would have thought something so easy would be such a pain in the
butt.
I solved it with embedded if-else clauses.
Thx all

Subject: [PHP] array, trouble updating
I usually work with cold fusion and took on a little project to get my
feet wet in php and am spinning my wheels. What I thought might be
difficult was easy and what I thought would be a piece of cake has
caused me much grief over the last few days.
I'm making a little shopping basket, writing the results to a file,
ftping the file to a distributor and sending the CC data to merchant
services company.
Write to file - easy
FTP file to distributor - easy
Updating the array in the shopping basket -- not so easy !!??!!
A shopping basket should be able to add and delete items (done)
You should be able to delete the whole basket (done)
Now I need to be able to update quantity - I've spent at least 5 or 6
hours on this and have gotten nowhere!!! This learning exercise is
getting to be a major time drag.
Any hints would be good.
The code is below:
<?php
if ($action == "empty")
{
while ($ses_basket_items > -1)
{
array_splice ($ses_basket_name,
$ses_basket_items, 1);
array_splice ($ses_basket_amount,
$ses_basket_items, 1);
array_splice ($ses_basket_price,
$ses_basket_items, 1);
array_splice ($ses_basket_id,
$ses_basket_items, 1);
$ses_basket_items--;
}
}
if ($action2 == "deleteItem")
{
array_splice ($ses_basket_name, $position, 1);
array_splice ($ses_basket_amount, $position, 1);
array_splice ($ses_basket_price, $position, 1);
array_splice ($ses_basket_id, $position, 1);
$ses_basket_items--;
}
?>
<?php
if ($_GET['basket']!=""){
if (session_is_registered('ses_basket_items')){
$basket_position_counter=0;
$double=0;
if ($_SESSION['ses_basket_items']>0){
foreach ($_SESSION['ses_basket_name'] as $basket_item){
if ($basket_item==$_GET['basket']){
$double=1;
$subtract=1;
$basket_position=$basket_position_counter;
}
$basket_position_counter++;
}
}
if ($double==1){
$oldamount=$_SESSION['ses_basket_amount'][$basket_position];
$_SESSION['ses_basket_amount'][$basket_position]++;
$amount=$_SESSION['ses_basket_amount'][$basket_position];
$oldprice=$_SESSION['ses_basket_price'][$basket_position];
$newprice=($oldprice/$oldamount)*$amount;
$_SESSION['ses_basket_price'][$basket_position]=$newprice;
}else{
$_SESSION['ses_basket_name'][]=$_GET['basket'];
$_SESSION['ses_basket_amount'][]=1;
$_SESSION['ses_basket_price'][]=$_GET['price'];
$_SESSION['ses_basket_id'][]=$_GET['id'];
$_SESSION['ses_basket_items']++;
}
}else{
$_SESSION['ses_basket_items']=1;
$_SESSION['ses_basket_name'][0]=$_GET['basket'];
$_SESSION['ses_basket_amount'][0]=1;
$_SESSION['ses_basket_price'][0]=$_GET['price'];
$_SESSION['ses_basket_id'][0]=$_GET['id'];
session_register("ses_basket_items");
session_register("ses_basket_name");

// basket output
$price=sprintf("%01.2f",$_SESSION['ses_basket_price'][$basket_counter]);
$amount=$_SESSION['ses_basket_amount'][$basket_counter];
$name=$_SESSION['ses_basket_name'][$basket_counter];
$aaa=$basket_counter;
echo "$amount $name $price";
echo "<a href=\"2.php?action2=deleteItem&position=" . $aaa .
"\">DEL</a>";
echo "<a
href=\"2.php?id=1001&price=25&basket=mouse&subtract=yes\">-sub</a>";
echo "$aaa";
echo "<BR>\n";
}
} else {
$_SESSION['ses_basket_items']=0;

I'm trying to use libxml_set_streams_context() to load a remote xml
file via HTTP conditional GET with DOMDocument::load() by stuffing an
'If-Modified-Since: --- " HTTP header into the stream, but no matter
how I try it I always get an HTTP 200 response when I know the last-
modified date is well before my if-modified date string.
I've confirmed via curl -H on the command line that I can do it
properly and get an HTTP 304 as expected, but I don't know what I'm
not doing right with libxml_set_streams_context(). Here's my code:
$opts = array('http'=>array('method'=>"GET", 'header'=>"If-Modified-
Since: Wed, 18 May 2005 23:55:29 GMT\r\n"));
$context = stream_context_create($opts);
libxml_set_streams_context($context);
$doc->load('http://www.somewhere.com/somefile.xml');
echo $doc->saveXML();
using the same $context resource, this also produces the same result,
when I expect it should work.
file_get_contents('http://www.somewhere.com/somefile.xml', false,
$context);
I have php 5.0.4 compiled with libxml2 (2.6.16) on Mac OS X 10.4. I
imagine I'm not doing something correctly, but can't figure out what
it is.
Any help?

Where is your error checking?
I don't know much about that fancy new stream stuff, or the XML crap, but
you've got zero (0) lines of code in there to do anything useful when the
functions fail.
If you ask the functions nicely, they almost always tell you EXACTLY what
went wrong.

no functions fail.
what I'm expecting is that with libxml_set_streams_context(), I've
correctly sent an HTTP "If-Modified-Since" Request Header along with
the HTTP GET in the DOMDocument::load() call. what I'm seeing is that
somehow I haven't, since the the DOMDocument::load() call returns the
file (with an HTTP 200 status in the response header) even though I
know the file has not been modified since the "If-Modified-Since"
date (confirmed by looking at the "Last-Modified" date in the
response header).
the fact that there is no failure, and no error message that I can
examine or test is exactly why I'm scratching my head and asking if
anyone who does know something about stream contexts can offer some
pointers.
I don't think I need any help with "the XML crap", as you put it.

Thanks Richard Lynch,
I found same error in error_log file which I face on command prompt before
then I install PHP 5.0 with --with-oci8=$ORACLE_HOME compilation so that
problem solved. Now I'm facing same problem on Apache. So can you tell me
where should I define the environment variables on Apache.
Thanks,
Regards,
Nayeem.

You logged in as you.
The PHP user runs as somebody else.
That other user does not have the same permissions/rights as you, and not
the same environment variables ($PATH in shell) and not even the same
shell.
If you can 'su' to that other user and run it, you may find out why it
fails. You should also check error logs as suggested, and use "View
Source" in your browser to see if the "blank" page is really blank, or
just buried inside an unfinished HTML tag.

You need to put the variables in single quotes, otherwise mysql treats
it as a column name. You should also escape the strings to be safe if
magic_quotes are turned off in php.ini
A bit like this:
mysql_select_db("status", $db);
$username = mysql_escape_string($_POST["username"]);
$password = mysql_escape_string($_POST["password"]);
$result = mysql_query("
SELECT customer_id
FROM Customers
WHERE customer_username = '$username'
AND customer_password = '$password'") or die (mysql_error());
$myrow = mysql_fetch_row($result);
$customer_id = $myrow[0];
$_SESSION['customer_id'] = $customer_id;

Tom

I expect (indeed I sincerely hope) that customer_username AND
customer_password columns are character datatypes. So it would be a good
idea to put single quotes around the values you are trying to select
from them.
