How can an array be used to store and remove duplicate entries before inserting data into table x_worldsp?

To store and remove duplicate entries before inserting data into table x_worldsp, we can use an array to keep track of the unique values. Before inserting each data entry into the table, we can check if it already exists in the array. If it does not, we can insert it into the table and add it to the array. This way, we ensure that only unique entries are inserted into the table. 

// Connect to the database
$pdo = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password');

// Data to be inserted into the table
$data = ['entry1', 'entry2', 'entry3', 'entry1', 'entry4'];

// Array to store unique entries
$uniqueEntries = [];

foreach($data as $entry) {
    if(!in_array($entry, $uniqueEntries)) {
        // Insert the entry into the table
        $stmt = $pdo->prepare("INSERT INTO x_worldsp (entry) VALUES (:entry)");
        $stmt->bindParam(':entry', $entry);
        $stmt->execute();

        // Add the entry to the array of unique entries
        $uniqueEntries[] = $entry;
    }
}
