PHP/SQL - How can I display distinct values and the number of occurrences?
1
So I am currently using PHP to pull the bodies from emails, parse the data, and insert the data into a user-created DB. I want to display an overview of the data (that is inside the DB) using PHP. Here is an example of what I want to achieve:
This is my table:
Table Name: bldgSensors
sensor_code | temp_limit | current_temp
---------------------------------------
0102260100A | 55 | 45
0102260100B | 55 | 50
0102260100A | 55 | 48
Desired output using PHP:
Sensors Count
0102260100A 2
0102260100B 1
So far, I can find distinct values but cannot output the total count:
$result1 = mysqli_query($DBconn,"SELECT DISTINCT sensor_code FROM bldgSensors");
echo "<table border='1'>
<tr>
<th>Distinct sensor codes</th>
<th>Count</th>
</tr>";
while($row1 = mysqli_fetch_array($result1))
{
echo "<tr>";
echo "<td>" . $row1['sensor_code'] ."</td>";
}
echo "</table>";
mysqli_close($DBconn);
Thanks so much in advance! This will help tremendously!

You can do that by modifying your query. Use the COUNT and GROUP BY sql functions:
Try this:
$query = "SELECT
sensor_code,
COUNT(sensor_code) AS sensorCount
FROM bldgSensors
GROUP BY sensor_code
ORDER BY sensorCount DESC";
$result1 = mysqli_query($DBconn, $query);
echo
'<table border="1">
<tr>
<th>Distinct sensor codes</th>
<th>Count</th>
</tr>';
while($row1 = mysqli_fetch_array($result1)){
echo
'<tr>' .
'<td>' . $row1['sensor_code'] . '</td>' .
'<td>' . $row1['sensorCount'] . '</td>' .
'</tr>';
}
echo
'</table>';
mysqli_close($DBconn);
