Mapping MySQL to PHP

Question

So far, I have this program that links my phpmyadmin database with my php script. Now I need to display certain things in the table, such as “all records”, “all contacts whose last name begins with S”, “all pet owners”, etc. My question is: is there an easier way to embed code in my PHP script to display information from my database. Right now I have this long echo application for displaying information. Is there a way that I can just use something like a SELECT * statement to display all records and simplify the code?

<?php
    $db_hostname='localhost';
    $db_username='root';
    $db_password='';
    $db_database='Address Book';

    $connection = new mysqli(   $db_hostname,
                                $db_username,
                                $db_password,
                                $db_database);

    if ($connection->connect_error) {
        echo "Sorry";
    } else {
        echo "Connected!<br><br>";      
        $sql = "SELECT * FROM People";
        $result = $connection->query($sql);
        if (!$result) die ($connection->error);
        $n = $result->num_rows;     

        for ($i=1; $i<=$n; $i++) {
            $row = $result->fetch_array(MYSQLI_ASSOC);

    echo "<table>
            <tr><th>ID</th><th>First Name</th><th>Last Name</th>
            <th>Street Address</th><th>City</th>
            <th>State</th><th>Zip Code</th>
            <th>Email Address</th><th>Comment</th>
            <th>Number of pets</th></tr>";

        echo "<tr><td width=20>" . $row['iD'] . "</td><td>" . $row['First Name'] . "</td><td width=40>" .
                $row['Last Name'] . "</td><td width=200>" . $row['Street Address'] . "</td><td width=30>" .
                $row['City'] . "</td><td width=40>" . $row['State'] . "</td><td width=30>" .
                $row['Zip Code'] . "</td><td width=40>" . $row['Email Address'] . "</td><td width=20>" .
                $row['Comment'] . "</td><td width=10>" . $row['Number of pets'] . "</td></tr>";
        }
        echo "</table>";
    }
?>

, PHP- . :

 // Put your MYSQLI retrievals codes here
?>
<table>
  <tr>
    <th>FIELD_1</th>

    <th>FIELD_3</th>
  </tr>

<?php
while ($rows = $result->fetch_array(MYSQLI_ASSOC))
{
?>
  <tr>
    <td><?php echo $rows['field_1']; ?></td>
    <td><?php echo $rows['field_2']; ?></td>

Hope this works for you:

<?php
$db_hostname='localhost';
$db_username='root';
$db_password='';
$db_database='Address Book';

$connection = new mysqli($db_hostname,$db_username,$db_password,$db_database);
if ($connection->connect_errno) {
    echo "Failed to connect to MySQL: (" . $mysqli->connect_errno . ") " . $mysqli->connect_error;
} else {
    echo "Connected!<br><br>";
}

$last_name = "Lastname to search"; //You can post or get lastname in here.
/* create a prepared statement */
if ($sql = $connection->prepare("SELECT * FROM People WHERE `Last Name`=?")) {
    /* bind parameters for markers */
    $sql->bind_param("s", $last_name);
    /* execute query */
    $sql->execute();
    /* instead of bind_result: */
    $result = $sql->get_result();
    /* close statement */
    $sql->close();
}
?>
<table>
    <thead>
        <tr>
            <th>ID</th>
            <th>First Name</th>
            <th>Last Name</th>
            <th>Street Address</th>
            <th>City</th>
            <th>State</th>
            <th>Zip Code</th>
            <th>Email Address</th>
            <th>Comment</th>
            <th>Number of pets</th>
        </tr>
    </thead>
    <tbody>
    <?
    /* now you can fetch the results into an array */
    while ($row = $result->fetch_assoc()) {
    ?>
        <tr>
            <td width=20><?=$row['iD'];?></td>
            <td><?=$row['First Name'];?></td>
            <td width=40><?=$row['First Name'];?></td>
            <td width=200><?=$row['Street Address'];?></td>
            <td width=30><?=$row['City'];?></td>
            <td width=40><?=$row['State'];?></td>
            <td width=30><?=$row['Zip Code'];?></td>
            <td width=40><?=$row['Email Address'];?></td>
            <td width=20><?=$row['Comment'];?></td>
            <td width=10><?=$row['Number of pets'];?></td>
        </tr>
    <?
    }
    ?>
    </tbody>
