How can PHP be used to select and manipulate specific records in a table displayed in a web page?

To select and manipulate specific records in a table displayed on a web page using PHP, you can use SQL queries to fetch the desired records from the database and then use PHP to display and manipulate the data accordingly. You can use conditional statements and loops to filter and display specific records based on certain criteria. Additionally, you can use HTML forms and PHP scripts to allow users to interact with the data and perform actions such as editing or deleting records. 

<?php
// Connect to the database
$connection = mysqli_connect("localhost", "username", "password", "database");

// Check connection
if (!$connection) {
    die("Connection failed: " . mysqli_connect_error());
}

// Select specific records from the table
$sql = "SELECT * FROM table_name WHERE column_name = 'criteria'";
$result = mysqli_query($connection, $sql);

// Display the records in a table
echo "<table>";
while ($row = mysqli_fetch_assoc($result)) {
    echo "<tr><td>" . $row['column1'] . "</td><td>" . $row['column2'] . "</td></tr>";
}
echo "</table>";

// Close the connection
mysqli_close($connection);
?>
