PHP get value from associative array by variable from loop - php

Question

I'm not sure my question is right.
I have made a html table and filled it with test data from the database.

This is my table:
<table class="table table-striped table-bordered turnover_list">
<thead>
<tr class="sorting_1">
<th>Company</th>
<th>Year</th>
<th>January</th>
<th>February</th>
<th>March</th>
<th>April</th>
<th>May</th>
<th>June</th>
<th>July</th>
<th>August</th>
<th>September</th>
<th>October</th>
<th>November</th>
<th>December</th>
<th>Total</th>
</tr>
</thead>
<tbody>
<?php
$currentYear = date('Y');
$check = "SELECT * FROM turnover WHERE year = '" . $currentYear . "'";
$result = mysql_query($check) or die(mysql_error());
foreach ($allCompanies as $companyName) {
$companyTurnoverTotal = 0;
$turnoverTotal = 0;
echo "<tr>";
echo "<td style='width:7%;'>" . $companyName . "</td>";
echo "<td style='width:7%;'>" . $currentYear . "</td>";
$monthTotal = array("January"=>"0", "February"=>"0", "March"=>"0", "April"=>"0", "May"=>"0", "June"=>"0", "July"=>"0", "August"=>"0", "September"=>"0", "October"=>"0", "November"=>"0", "December"=>"0");
foreach ($months as $month) {
$sql = "SELECT SUM(mob + www) AS 'turnover' FROM turnover WHERE year = '" . $currentYear . "' AND companyID = '" . getCompanyID($companyName) . "' AND month = '" . $month . "'";
$result = mysql_query($sql) or die(mysql_error());
$row = mysql_fetch_assoc($result);
$companyTurnoverMonth = $row['turnover'];
$monthTotal[$month] += $companyTurnoverMonth;
echo "<script>alert('" . $month . ": " . $monthTotal[$month] . "')</script>";
$companyTurnoverTotal += $companyTurnoverMonth;
$turnoverTotal += $companyTurnoverTotal;
echo "<td style='width:7%;'>" . make_format($companyTurnoverMonth) . "</td>";
}
echo "<td style='width:7%; font-weight: bold; background-color:#d3d3d3;'>" . make_format($companyTurnoverTotal) . "</td>";
echo "</tr>";
}
echo "<tr style='font-weight: bold; background-color:#d3d3d3;'>";
echo "<td style='width:7%;'>" . "Total" . "</td>";
echo "<td style='width:7%;'>" . $currentYear . "</td>";
echo "<td style='width:7%;'>" . make_format($monthTotal['January']) . "</td>";
echo "<td style='width:7%;'>" . make_format($monthTotal['February']) . "</td>";
echo "<td style='width:7%;'>" . make_format($monthTotal['March']) . "</td>";
echo "<td style='width:7%;'>" . make_format($monthTotal['April']) . "</td>";
echo "<td style='width:7%;'>" . make_format($monthTotal['May']) . "</td>";
echo "<td style='width:7%;'>" . make_format($monthTotal['June']) . "</td>";
echo "<td style='width:7%;'>" . make_format($monthTotal['July']) . "</td>";
echo "<td style='width:7%;'>" . make_format($monthTotal['August']) . "</td>";
echo "<td style='width:7%;'>" . make_format($monthTotal['September']) . "</td>";
echo "<td style='width:7%;'>" . make_format($monthTotal['October']) . "</td>";
echo "<td style='width:7%;'>" . make_format($monthTotal['November']) . "</td>";
echo "<td style='width:7%;'>" . make_format($monthTotal['December']) . "</td>";
echo "<td style='width:7%;'>" . make_format($turnoverTotal) . "</td>";
echo "</tr>";
?>

I want a table column at the right that shows the total of every company.
At the bottom of the table I want a row with columns per month that shows the total of every month.
I was trying to make an array with all the months and increase the value with the next column in the same month. $monthTotal[$month] += $companyTurnoverMonth;
foreach ($months as $month) {
$sql = "SELECT SUM(mob + www) AS 'turnover' FROM turnover WHERE year = '" . $currentYear . "' AND companyID = '" . getCompanyID($companyName) . "' AND month = '" . $month . "'";
$result = mysql_query($sql) or die(mysql_error());
$row = mysql_fetch_assoc($result);
$companyTurnoverMonth = $row['turnover'];
$monthTotal[$month] += $companyTurnoverMonth;
$companyTurnoverTotal += $companyTurnoverMonth;
$turnoverTotal += $companyTurnoverTotal;
echo "<td style='width:7%;'>" . make_format($companyTurnoverMonth) . "</td>";
}
