Question

I need a help in a query rows creating a table through php. Here below is the rows in my mysql table named "routine".
Now i want to fetch through week days in a single loop creating a table like below:
Is it possible with a single loop? Here i want to separate the rows through week and auto columns through time.

Answer 1

Yes! It is possible with single loop but we use php array...
Try this...
Data insertion php coding - insert.php
<?php
$servername = "localhost";
$username = "root";
$password = "";
$database = "my_db";
// Create connection
$conn = new mysqli($servername, $username, $password, $database);
$week = "Friday";
$subject = "Physics";
$time = 3;
$sql = "INSERT INTO routine (Week, Subject, Time)VALUES ('".$week."', '".$subject."', '".$time."')";
if ($conn->query($sql) === TRUE) {
echo "New record created successfully";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
$conn->close();
?>
Php code for displaying rows through week and auto columns through time - view.php
<?php
$servername = "localhost";
$username = "root";
$password = "";
$database = "my_db";
// Create connection
$conn = new mysqli($servername, $username, $password, $database);
//Initial Declarations
$data = [];
$data[0][0] = "<tr><td>Week</td>";
$data[0][1] = "<tr><td>Monday</td>";

$data[3][1] = "<tr><td>Thursday</td>";
$data[3][2] = 0;
$data[4][0] = "<tr><td>Week</td>";
$data[4][1] = "<tr><td>Friday</td>";
$data[4][2] = 0;
$sql = "SELECT * FROM routine";
$result = mysqli_query($conn, $sql);
while($row = mysqli_fetch_array($result, MYSQLI_NUM)) // Table Fields - Week ($row[0]), Subject($row[1]), Time($row[2])
{
if($row[0] == "Monday")
{
$data[0][0] = $data[0][0] . "<td>" . $row[2] . "</td>";
$data[0][1] = $data[0][1] . "<td>" . $row[1] . "</td>";
$data[0][2] = intval($data[0][2]) + 1;
}
else if($row[0] == "Tuesday")
{

}

{
$data[2][0] = $data[2][0] . "<td>" . $row[2] . "</td>";
$data[2][1] = $data[2][1] . "<td>" . $row[1] . "</td>";
$data[2][2] = intval($data[2][2]) + 1;
}
else if($row[0] == "Thursday")
{
$data[3][0] = $data[3][0] . "<td>" . $row[2] . "</td>";
$data[3][1] = $data[3][1] . "<td>" . $row[1] . "</td>";
$data[3][2] = intval($data[3][2]) + 1;
}
else if($row[0] == "Friday")
{
$data[4][0] = $data[4][0] . "<td>" . $row[2] . "</td>";
$data[4][1] = $data[4][1] . "<td>" . $row[1] . "</td>";
$data[4][2] = intval($data[4][2]) + 1;
}
}
//Final Assigning
