PHP Row and Column Count - php

Question

I was wondering if you guys can help me, I am pulling Data from a mysql database and I am looking to have the content echo in rows, like a shopping cart. Below is the code I am using. The Code is working flawlessly, but I don't know how to add the Row Count to it and Column Count to it.
Working Code:
<?
$dmealh = mysql_query("select count(*) from jobs_cart where mid='$mid'");
$jmealh = mysql_fetch_array($dmealh);
if ($jmealh[0]) {
$dmealh = mysql_query("select * from jobs_cart where mid='$mid' order by date desc, time desc");
while ($jmealh = mysql_fetch_array($dmealh)) {
echo "$id - $jmealh[name] - $jmealh[meals]";
}
}
?>
This is what I want the Data to look like:
Row Count- Name - Meal Count
1 - Greg - 3
2 - Mike - 4
3 - Tomm - 1
8 Meals Total

Answer 1

Just use a basic counter to keep track of what row you are on and use another variable to add up the meal count as you loop through your results and then echo out the final count. Throw it all into a table and you're set.
<?php
$dmealh = mysql_query("select count(*) from jobs_cart where mid='$mid'");
$jmealh = mysql_fetch_array($dmealh);
if ($jmealh[0]) {
$dmealh = mysql_query("select * from jobs_cart where mid='$mid' order by date desc, time desc");
$total_meals = 0; // Keep track of the total number of meals. Start at zero.
$row = 1; // Keep track of current row. Start at one.
?>
<table>
<?php
while ($jmealh = mysql_fetch_array($dmealh)) {
?>
<tr>
<td><?php echo $row; ?></td>
<td><?php echo $jmealh['name']; ?></td>
<td><?php echo $jmealh['meals']; ?></td>
</tr>
<?php
$total_meals += $jmealh[meals]; // Add to total meals
$row++; // Increase row count
}
?>
<tr>
<td></td>
<td></td>
<td><?php echo $total_meals; ?> Meals Total</td>
</tr>
</table>
}

Don't use mysql_* functions...they're deprecated (note the red box near the top).
Where does $mid come from? Make sure to escape your database inputs to prevent SQL injection.
You're doing extra work by first querying to see if any rows are returned. Just do the SELECT query and while loop. If no rows are returned, the loop will not execute.
You should be using an HTML table to display this data. Use PHP variables to keep track of your sums.
A crude example:
$mid = mysqli_real_escape_string($mid);
$rows = $total = 0;
$result = mysqli_query("SELECT name, meals FROM jobs_cart WHERE mid = '$mid' ORDER BY date DESC, time DESC");
echo '<table>';
while ($row = mysqli_fetch_assoc($result)) {
$rows++;
$total += $row['meals'];
echo '<tr><td>'. $rows .'</td><td>'. $row['name'] .'</td><td>'. $row['meals'] .'</td></tr>';
}
echo '<tr><td> </td><td> </td><td>'. $total .'</td></tr></table>';
