How can PHP be used to automatically correct and update names in a database based on certain conditions or criteria?

When updating names in a database based on certain conditions or criteria, you can use PHP to create a script that fetches the relevant data from the database, applies the necessary corrections or updates, and then updates the database with the corrected names. This can be achieved by writing a PHP script that connects to the database, retrieves the data based on the specified criteria, processes the names, and then updates the database accordingly.

<?php

// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Fetch data from the database based on certain criteria
$sql = "SELECT id, name FROM users WHERE condition = 'criteria'";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // Update names based on conditions
    while($row = $result->fetch_assoc()) {
        $id = $row["id"];
        $name = $row["name"];

        // Apply corrections or updates to the name
        $correctedName = // Your correction logic here

        // Update the database with the corrected name
        $updateSql = "UPDATE users SET name = '$correctedName' WHERE id = $id";
        $conn->query($updateSql);
    }
} else {
    echo "No results found";
}

// Close the connection
$conn->close();

?>
