How to showing report that group by archieve with PHP & MySQL? - php

Question

I want to recapitulate report that grouped by month. But the results of sum is incorrect. It's just sum data in one month and show in all rows.
<?php
$query = mysql_query("SELECT * FROM barang GROUP BY arsip");
$i = 1;
while ($data = mysql_fetch_assoc($query)) {
?>
<tr class="<?php if ($i % 2 == 0) { echo "odd"; } else { echo "even"; } ?>">
<td><?php echo $i; ?></td>
<td><?php echo $data['arsip']; ?></td>
<td><?php
$Masuk= mysql_query("SELECT SUM(barang_in) AS masuk FROM barang GROUP BY arsip");
if($Masuk){
$data = mysql_fetch_assoc($Masuk);
echo $data['masuk'];
}
?></td>
<td><?php
$keluar= mysql_query("SELECT SUM(bijih_out+htm_out+pth_out) AS keluar FROM barang GROUP BY arsip");
if($keluar){
$data = mysql_fetch_assoc($keluar);
echo $data['keluar'];
}?></td>
<td><?php
$efisiensi= mysql_query("SELECT SUM((bijih_out+htm_out+pth_out)-barang_in) AS efisiensi FROM barang GROUP BY arsip");
if($efisiensi){
$data = mysql_fetch_assoc($efisiensi);
echo $data['efisiensi'];
}
?></td>
<td><?php
$persen= mysql_query("SELECT SUM(barang_in/(bijih_out+htm_out+pth_out))*1 AS persen FROM barang GROUP BY arsip");
$simbol = "%";
if($persen){
$data = mysql_fetch_assoc($persen);
echo number_format($data['persen'],2); echo $simbol;
}
?></td>
<?php
$i++;
}
?>
so that's my code. what's wrong with that? There are some columns for displaying income items, outcome items, efficiency ( difference of outcome and income items ) and percent of efficiency.

Answer 1

finally I found out the right code. Thankyou for #RandomSeed who helps me. This is my final code and it works!
<?php
$query = mysql_query("SELECT arsip, SUM(barang_in) AS income, SUM(bijih_out+htm_out+pth_out) AS outcome, SUM((bijih_out+htm_out+pth_out
)-barang_in) AS efficiency, SUM((barang_in / ( bijih_out + htm_out + pth_out))*100) AS percent FROM barang GROUP BY arsip");
$i = 1;
while ($data = mysql_fetch_assoc($query)) {
?>
<tr class="<?php if ($i % 2 == 0) { echo "odd"; } else { echo "even"; } ?>">
<td><?php echo $i; ?></td>
<td><?php echo $data['arsip']; ?></td>
<td><?php echo $data['income']; ?></td>
<td><?php echo $data['outcome']; ?></td>
<td><?php echo $data['efficiency']; ?></td>
<td><?php $simbol = "%"; echo number_format($data['percent'],0); echo $simbol; ?></td>
<?php
$i++;
}
?>
