How can the concept of linking words in a text be efficiently implemented and stored in a PHP/MySQL application?

To efficiently implement and store the concept of linking words in a text in a PHP/MySQL application, you can create a database table to store the linking words along with their corresponding text IDs. When processing a text, you can retrieve the linking words from the database and use them to create hyperlinks or perform other actions based on the linking words found in the text.

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

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

// Retrieve linking words from database
$sql = "SELECT word, text_id FROM linking_words";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // Output data of each row
    while($row = $result->fetch_assoc()) {
        $linking_words[$row['word']] = $row['text_id'];
    }
} else {
    echo "0 results";
}

// Process text and create hyperlinks for linking words
$text = "Your text goes here with linking words like 'example' and 'test'";
$words = explode(" ", $text);

foreach($words as $word) {
    if(array_key_exists($word, $linking_words)) {
        echo "<a href='text.php?id=" . $linking_words[$word] . "'>" . $word . "</a> ";
    } else {
        echo $word . " ";
    }
}

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