How can the SQL LIKE command be effectively used to determine if an article is related to another in a database?

To determine if an article is related to another in a database using the SQL LIKE command, you can search for common keywords or phrases between the two articles. By using the LIKE command with wildcard characters (%), you can search for similarities in the article content or title. This can help identify related articles based on shared keywords or phrases.

<?php
// Assuming $article1 and $article2 contain the article content or title to compare

// Establish a database connection
$connection = new mysqli("localhost", "username", "password", "database");

// SQL query to check for related articles using the LIKE command
$query = "SELECT * FROM articles WHERE content LIKE '%$article1%' OR title LIKE '%$article1%' OR content LIKE '%$article2%' OR title LIKE '%$article2%'";

// Execute the query
$result = $connection->query($query);

// Check if any related articles were found
if ($result->num_rows > 0) {
    // Related articles found
    while ($row = $result->fetch_assoc()) {
        echo "Related article found: " . $row['title'] . "<br>";
    }
} else {
    // No related articles found
    echo "No related articles found.";
}

// Close the database connection
$connection->close();
?>
