[ijustdidit2011]

I think im so lost im dead in a ditch somewhere! Trying to write basic inventory program and i cant get it to get out to the other files and i think i have screwed up the functions!

 

<?php

 

//main

$ordernumber=0;

$itemID= "";

$qtyOnHand =0;

$qtyRequested= 0;

$qtyShipped = 0;

$qtyBO = 0;

$message = "";

$fileBo;

$fileshipped;

 

 

prepShippedFile($fileshipped);

prepBoFile($fileBo);

 

print("\nEnter the order number or 0 to exit: ");

fscanf(STDIN,"%d", $ordernumber);

while($ordernumber !=0)

{

  print("\n a new order . . . ");

  print("\nEnter the Quantity for item: ");

  fscanf(STDIN,"%d", $qtyRequested);

 

  print("\nEnter the Quantity in store: ");

  fscanf(STDIN,"%d", $qtyOnHand);

  print("\nEnter the item id or 0 to exit order: ");

  fscanf(STDIN,"%s", $itemID);

 

     

while($itemID !="0")

  {

        doCalcs(&$qtyRequested,$qtyOnHand,$qtyShipped,$qtyBO,$message);

    writeReports($fileshipped,$fileBo,$itemID,$qtyShipped,$qtyBO);

 

    print("\nEnter the item id or 0 to exit order: ");

    fscanf(STDIN,"%s", $itemID);

  }

 

print("\nEnter the order number or 0 to exit: ");

fscanf(STDIN,"%d", $ordernumber);

}

 

 

 

    //end main

    function prepShippedFile(&$fileshipped)

    {

  $fileshipped = fopen ("shipped.txt",'w') or die ("no file created");

  fprintf($fileshipped, "\n        SHIPPED REPORT\n\n");

  fprintf($fileshipped, "\n    Item  QTY\n\n");

    }

    function  prepBoFile(&$fileBo)

    {

  $fileBo = fopen ("backorder.txt",'w') or die ("no file created");

  fprintf($fileBo, "\n        BACKORDER REPORT\n\n");

  fprintf($fileBo, "\n    Item  QTY\n\n");

    }

    function doCalcs(&$qtyRequested,$qtyOnHand,$qtyShipped,$qtyBO,$message)

    {

    if($qtyRequested <= $qtyOnHand)

    {

    $qtyBO = $qtyBO++;

    }

    else

    {

    $qtyShipped= $qtyShipped++; 

    }

    }

    function writeReports($fileshipped,$fileBo,$itemID,&$qtyShipped,&$qtyBO)

    {

    if($qtyShipped == $qtyShipped)

        }

    else
