How can the use of named values in a PDOStatement::execute() call affect the execution of an SQL query in PHP?

When using named values in a PDOStatement::execute() call, it is important to ensure that the named values match the placeholders in the SQL query. If the named values do not match the placeholders, the query may not execute correctly or may result in errors. To fix this issue, make sure that the named values in the execute() call correspond to the placeholders in the SQL query. 

// Incorrect usage of named values in PDOStatement::execute()
$stmt = $pdo->prepare("SELECT * FROM users WHERE id = :user_id");
$stmt->execute(['name' => $user_id]); // Incorrect named value 'name'

// Correct usage of named values in PDOStatement::execute()
$stmt = $pdo->prepare("SELECT * FROM users WHERE id = :user_id");
$stmt->execute(['user_id' => $user_id]); // Correct named value 'user_id'
