Stock Method


Php-er,

I've been working on severals stock reporting and processing. And i've tried many ways to achieve one. And finally i've came with final. This is it check it out.


Source code:


require_once 'classCol/misc.php';
require_once 'classCol/classStockCalc.php';

/**
* Example: Lets say we have 5 stock entry.
* We arrange them in this format
* DATE---QTY---PRICE---VALUE---REFERENCE
* where: "---" is delimiter.
* Dont worry if one of the value is negative
* since the filter will only take --- exactly.
*
*/
$isDbg = _IS_DEBUG;
$CStockCalc = new stockCalc;

$egTx = array("STOCK_DATE" => array("01-06-2008",
"02-06-2008",
"03-06-2008",
"04-06-2008",
"05-06-2008"),
"QTY" => array("1000",
"2000",
"1000",
"2000",
"1000"),
"PRICE" => array("200",
"400",
"300",
"400",
"250"),
"VALUE" => array("200000",
"800000",
"300000",
"800000",
"250000"),
"REFERENCE" => array("000001/STKOUT/06-2008",
"000002/STKOUT/06-2008",
"000003/STKOUT/06-2008",
"000004/STKOUT/06-2008",
"000005/STKOUT/06-2008",
"000006/STKOUT/06-2008"));

$szEgTx = sizeof($egTx["REFERENCE"]) - 1; //downtop loop, subs by one
for($iTx = $szEgTx; $iTx >= 0; $iTx--){ //where $iTx >= 0

$dataTx = $egTx["STOCK_DATE"][$iTx] ."---".
$egTx["QTY"][$iTx] ."---".
$egTx["PRICE"][$iTx] ."---".
$egTx["VALUE"][$iTx] ."---".
$egTx["REFERENCE"][$iTx];

$CStockCalc->addDetails($dataTx);
}

$qtyOut = 2500;

//calculate the FIFO
$CStockCalc->calcFifo($qtyOut);

$resQtyOut = $CStockCalc->getQtyOutDetails();

$resQtyBal = $CStockCalc->getQtyBalDetails();

dbgInfo("resQtyOut",$resQtyOut["QTY"],$isDbg);
dbgInfo("resQtyOut",$resQtyOut["VALUE"],$isDbg);
dbgInfo("resQtyBal",$resQtyBal["QTY"],$isDbg);
dbgInfo("resQtyBal",$resQtyBal["VALUE"],$isDbg);


Yup, itu aja. Silahkan method nya dipilih sendiri utk fifo, lifo ato average.
