[PHP] Shuffle Cards Function
I've written a ShuffleCards function that will actually shuffle a deck of
cards just like would happen in real life (divide the deck in half and stick
them into each other with 1-3 cards between each other card)
function ShuffleCards(&$cardsArray, $times)
{
// Randomizes where to split within center (-3 to +3 from dead center)
(MINIMUM 10 CARDS IN DECK)
// Splits into two array. Randomizes how many cards from left and how
many cards from right (between 1 and 3)
// Alternates sides. Continues until both arrays are empty.
$arraySize = count($cardsArray);
if($arraySize<10)
return;
$deadCenter = $arraySize/2;
for($i=0;$i<$times;$i++)
{
reset($cardsArray);
$cutVariant = rand(-3, 3);
$cutLocation = $deadCenter+$cutVariant;
$firstArray = array();
$secondArray = array();
for($z=0;$z<$arraySize;$z++)
{
if($z<$cutLocation)
array_push($firstArray, $cardsArray[$z]);
else
array_push($secondArray, $cardsArray[$z]);
}
$bottomFirst = rand(0, 1);
$cardsArray = array();
while(count($firstArray) && count($secondArray))
{
$leftNewCards = array();
$rightNewCards = array();
$leftVariant = rand(1, 3);
if($leftVariant>count($firstArray))
$leftVariant = count($firstArray);
$rightVariant = rand(1, 3);
if($rightVariant>count($secondArray))
$rightVariant = count($secondArray);
for($x=0;$x<$leftVariant;$x++)
{
array_push($leftNewCards, array_shift($firstArray));
}
for($y=0;$y<$rightVariant;$y++)
{
array_push($rightNewCards, array_shift($secondArray));
}
if($bottomFirst==0)
{
$newCardsArray = array_merge($leftNewCards, $rightNewCards);
$bottomFirst = 1;
}
else
{
$newCardsArray = array_merge($rightNewCards, $leftNewCards);
$bottomFirst = 0;
}
reset($newCardsArray);
while(count($newCardsArray))
{
array_push($cardsArray, array_shift($newCardsArray));
}
}
if(count($firstArray))
{
while(count($firstArray))
array_push($cardsArray, array_shift($firstArray));
}
if(count($secondArray))
{
while(count($secondArray))
array_push($cardsArray, array_shift($secondArray));
}
}
}

[PHP] More SNMP Functions for PHPv4
A while ago, Vilius Benetis, an engineer from Lithuania created some great new SNMP functions for PHP 3 (snmp_getnext(), etc.) Well I've modified the code so that it will compile under PHP v4 now. (This is a replacement to the PHP source code, and not actually PHP Code) It can be found at: http://www.ncinter.net/~bert/php-snmp-v4.tar.gz Enjoy.

Re: [PHP] Re: Shuffle Cards Function
Well, I required a function to mimick a human shuffle.
Because the online shuffle was to help the user predict what sort/types of
deals he would get with a given deck based upon a normal human shuffle.
Plus, I've heard some bad things about shuffle, and of course, shuffe
doesn't mimick a non-perfect human shuffle.

[PHP] Zend Optimizer under Linux Sparc
It appears as if the Zend Optimizer is distributed only in binary format. They have versions for Linux on i386 and versions for Solaris running on a Sparc Ultra processor. However, I'm running Linux RedHat on a Ultra Sparc processor. Is there any way I can install Zend Optimizer?

[PHP] Asynchronous SNMP?
I'm working on a project that involves a lot of SNMP data gathering. I was wondering if it's possible to have a multi-threaded PHP script. Basically the SNMP queries I'm running are taking a long time to complete (several seconds). However I found that running multiple at the same time does not slow down the response time of any of the others. So I was wondering how easy it would be to get 5 or 6 SNMP queries running at the same time. If PHP is unable to, I'm going to have to write a C/C++ app, that will do it, then insert the results into a database. Then the PHP script will grab from there.
