need help with php loop logic - php

Question

This code works perfectly except that it doesn't print the last 2 rows of my csv file:
This is the file:
603629,0,ATLV0008,"Vendor1",1942.60,11/04/2010,1942.60,9/1-9/30/10,EFT-JP
603627,2,ATLV0008,"Vendor1",1242.40,11/04/2010,1242.40,7/1-7/31/10,EFT-JP
600023,0,FLD4V0003,"Vendor2",1950.00,06/15/2010,1950.00,6/14/10 Request,EFT-JP
600024,0,FLD4V0003,"Vendor2",1800.00,06/15/2010,1800.00,6/14/10 Request,EFT-JP
603631,0,ATLV5066,"Vendor2",1000.00,11/09/2010,1000.00,11/4/10 Check Request,PM2
603647,0,ATLV5027,"DVendor3",2799.80,11/15/2010,2799.80,10/1-10/31/10 Bishop,PM2
603642,5,ATLV5027,"Vendor3",482.40,11/15/2010,482.40,10/1-10/18/10 Allen,PM2
603653,0,ATLV0403,"Vendor4",931.21,11/17/2010,931.21,9/1-9/30/10,EFT-JP
603661,0,ATLV0105,"Vendor5",26.75,11/19/2010,26.75,093139,PM2
603660,1,ATLV0105,"Vendor5",5.35,11/19/2010,5.35,093472,PM2
Here is the code: (It needs to display the sum of 2 rows with the same vendor before the actual rows)
if (($handle = fopen('upload/ATLANTA.csv', "r")) !== FALSE) {
while (($row_array = fgetcsv($handle, 1000, ","))) {
foreach ($row_array as $key => $val) {
$row_array[$key] = trim(str_replace('"', '', $val));
ob_flush();
}
$complete[] = $row_array;
ob_flush();
}
}
flush();
$prevVendor = '';
$sum = 0;
$venData = '';
if (isset($complete)) {
foreach ($complete as $key => $val) {
$venData .= "<br/>";
$currVendor = $complete[$key][3];
if ($currVendor != $prevVendor){
if ($prevVendor != NULL){
print "<br/>";
print $sum . "<br/>";
print $venData;
$sum = 0; $venData = '';
}
}
foreach ($val as $ikey => $ival){
if ($ikey != 1){
$venData .= $ival . '&nbsp';
$prevVendor = $val[3];
}
}
if ($currVendor == $prevVendor){
$sum += $complete[$key][6];
}
}
}

I don't really understand your problem but if you want to get (and save it wherever you want) the sum of each vendors, you should do something like this :
$prevVendor = null;
$venData = '';
$sums = array();
if (isset($complete) && is_array($complete)) {
$lim = count($complete);
for ($key=0;$key<$lim;++$key) { // no need foreach for simple array
$venData .= "<br/>";
$currVendor = $complete[$key][3];
if ($currVendor != $prevVendor){
if ($prevVendor != null){
print "<br/>";
print $venData;
}
$venData = '';
$prevVendor = $currVendor;
$sums[$currVendor] = 0; // set the counter to 0
}
foreach ($complete[$key] as $ikey => $ival){
if ($ikey != 1){
$venData .= $ival . ' '; // is useful for you I guess
}
}
$sums[$currVendor] += $complete[$key][6]; // add amounts
}
}
if ($prevVendor != null){ // you need to do this to display the last record
print "<br/>";
print $venData;
}
var_export($sums); // check results
This can be some syntax errors ...
