Re: [PHP] Creating an OO Shopping Cart
""Richard Lynch"" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] Contact the bank with which you already HAVE a merchant account for your point-of-sale credit card swiper thingies. You're already working with them, paying them good money for essentially the "same" services. Different Service Almost-for-sure they would be happy to provide you with on-line merchant account for not too much more than you already pay them. Not necessarily. In shop POS services are not generally provided by the banks either. They are usually provided by a seperate entity (which may be *owned* by a bank or several banks [aka Streamline in the UK] and do not necessarily provide online clearance as well [Streamline don't for example]. There are, however, a number of organisations that do online cc clearance and will work in partnership with most of the offline clearing houses. Your existing offline clearing-house/bank will usually provide you with a list of these, although, they generally *won't* recommend any particular one. If not, I'm guessing that their competitors WILL do a package deal of on-line and POS merchant account, for the same price you're paying now, to lure you away from your current bank. Firstly, they are not competitors - they are business partners with your POS provider and provide a service in conjunction with your existing provider. They will not replace it - for the simple reason, these online clearance companies are not banks - they are online payment *clearance* companies - the actual payments are still conducted through your existing bank accounts.

[PHP] Passing an indefinite number of parameters by reference
Hi, Currently I have a function which accepts a limited number of parameters: call_function($function_name, &$var_1, &$var_2); I wish to modify the function to accept an indefinite number of parameters, which may or may not be references. The function call_function() then calls the function specified in $function_name, with the variables passed as parameters to that function. Is this possible? Thanks for any help which can be offered.

I believe it is - BUT it won't be easy, also I think you can only really do this properly in php5 using a shedload of reflection functionality: http://php.net/manual/en/language.oop5.reflection.php although I wonder whether you shouldn't be re-evaluating what it is your trying to do because I get the impression it's a whole load of work for probably little payoff (consider that using alot of indirection in your code will make it harder to understand/read and therefore harder to debug/maintain). why not consider the possibility that all these 'by reference' args could be items in a single 'by reference' array? btw: have you met call_user_func_array() yet? (not that it would solve the problem because it doesn't 'do' references) - also, it's manual page offers a hack for the reference problem your working on.

Re: [PHP] Echo a value from an arrays position

This may clarify - in php, integer and associate arrays are created
arbitrarily, ie keys can be numbers or strings. So, either create an array
like this:
array('1' => 'first element',
'2' => 'second element');
if I'm not mistaken the above example will result in an array with
2 *numeric* keys because any strings keys that php that are numeric
(according to the logic of is_numeric()) will be seen as numeric keys.
so the above example could lead to even more confusion!
and call by the key!

Like position 2 in the array and not the key name.

One thing you could do is (assuming it's php4)
';
print_r($array);
echo '';
}
function call_function($name, &$params) {
call_user_func($name, $params);
}
function test(&$params) {
extract($params, EXTR_REFS);
printArray($myarray1);
printArray($myarray2);
// prove this is a reference by modifying it
$myarray2 = array('one', 'two', 'three');
}
$myarray1 = array(3, 6, 9);
$myarray2 = array('two', 'four', 'six');
$myParams['myarray1'] =& $myarray1;
$myParams['myarray2'] =& $myarray2;
call_function('test', $myParams);
// myarray2 now has the values set in test
printArray($myarray2);
?>
Output:
Array
(
[0] => 3
[1] => 6
[2] => 9
)
Array
(
[0] => two
[1] => four
[2] => six
)
Array
(
[0] => one
[1] => two
[2] => three
)
This is a bit of a pain though. :)

Here is a cutdown version of a class loader I use, It works for php4 and
php5 and with references. It should be easy to modify.
1) {
for ($i = 1; $i < $num_args; $i++) {
$vars .= ($i > 1)? ',':'';
$varname = 'variable'.$i;
$$varname =& $arg_list[$i];
$vars .= "\$$varname";
}
}
$vars .= ');';
eval($vars);
return $return;
}
?>

[PHP] Socket Functions in PHP
Hi all,
I suspect I'm having problems with socket functions within my PHP
application running on Red Hat 2.4.21-4.EL #1/PHP 4.3.2/Apache 2.0.46.
Below is a sample code listing:
function sendRequest($strRequest) {
$parser = NULL;
$logman = new LogManager();
$resource = socket_create( AF_INET, SOCK_STREAM, SOL_TCP );
$logman->append("Connecting to OLS Server...");
$socket_conn = socket_connect( $resource, $serverIP, $serverPort );
if( $socket_conn ) {
$logman->append("Connected to {$serverIP}:{$serverPort}. Sending XML
request...");
socket_write( $resource, $strRequest );
$logman->append("XML request sent. Waiting for XML
response...");
$document = "";
$data = socket_read( $resource, 1024 );
while ($data != "") {
$document .= $data;
$data = socket_read( $resource, 1024 );
}
$logman->append("XML response received.");
$parser = new OlsResponseParser;
// parse the received document using our parser
$parser->parse($document);
}
if ($parser != NULL) {
return $parser->getOlsResponse();
}
return $parser;
}
The following listing is from the logs I have created...
|+---+-++
| LogId | LogDate | LogMessage
|
+---+-++
|37 | 2006-05-03 15:39:28 | /new_userpage_process.php initialized.

|42 | 2006-05-03 15:40:34 | Buffering complete. Redirecting to
thanks.php?actiontype=2 |
+---+-++
As you can see, there is a lapse of more than one minutes between
LogId's 40 and 41, which is very slow on a production environment. The
script above acts as a client to another application server listening on
a remote port, running on Java. What the remote application reports is
that it receives the connection request, receives the request data, and
transmits the response data at the same second, while my application
receives the response one minute after the request was sent!
Other implementations in the enterprise using different architectures
and technologies/languages do not experience the same issue as my app does.
Please help. Comments, suggestions and thoughts through the group or
private mail are deeply appreciated.
Thanks!
