How can the function ODBCArtikelpruefung be properly integrated into the existing code to check for the existence of an article number in the database?

Issue: The function ODBCArtikelpruefung needs to be integrated into the existing code to check if an article number exists in the database before proceeding with any operations related to that article. Solution: To integrate the ODBCArtikelpruefung function into the existing code, we can call it before performing any database operations with the article number. If the function returns true, the article exists in the database and further operations can proceed. If it returns false, the article does not exist and appropriate action can be taken.

// Existing code
$articleNumber = $_POST['article_number'];

// Integrate ODBCArtikelpruefung function
if(ODBCArtikelpruefung($articleNumber)) {
    // Article exists in the database, proceed with operations
    // Example: Fetch article details from the database
    $articleDetails = fetchArticleDetails($articleNumber);
    
    // Example: Display article details
    echo "Article Number: " . $articleDetails['article_number'] . "<br>";
    echo "Article Name: " . $articleDetails['article_name'] . "<br>";
} else {
    // Article does not exist in the database, display error message
    echo "Article not found in the database.";
}
