Is it necessary to include the variable "artnr" in both the query and bindValue functions when retrieving data from a database in PHP?

Yes, it is necessary to include the variable "artnr" in both the query and bindValue functions when retrieving data from a database in PHP. This ensures that the value of "artnr" is properly bound to the query and executed correctly to fetch the desired data from the database. 

// Assuming $artnr is the variable containing the value to be retrieved
$artnr = 12345;

// Prepare the SQL query with a placeholder for the variable
$query = $pdo->prepare("SELECT * FROM table_name WHERE artnr = :artnr");

// Bind the value of $artnr to the placeholder in the query
$query->bindValue(':artnr', $artnr);

// Execute the query
$query->execute();

// Fetch the data from the database
$result = $query->fetch();
