Since PHP 8.1 you can pass an array directly to execute: $sql = “INSERT INTO users (email, password) VALUES (?,?)”; // sql $stmt = $mysqli->prepare($sql); // prepare $stmt->execute([$email, $password]); // execute with data! For the earlier versions the task is a bit elaborate but doable. For a simple case when you already have a query … Read more
You could also say: SELECT wrd FROM tablename WHERE wrd LIKE CONCAT(:partial, ‘%’) to do the string joining at the MySQL end, not that there’s any particular reason to in this case. Things get a bit more tricky if the partial wrd you are looking for can itself contain a percent or underscore character (since … Read more

Just replace all the variables with ?. $sql = “UPDATE Applicant SET phone_number=?, street_name=?, city=?, county=?, zip_code=?, day_date=?, month_date=?, year_date=? WHERE account_id=?”; $stmt = $db_usag->prepare($sql); // This assumes the date and account_id parameters are integers `d` and the rest are strings `s` // So that’s … Read more

To bind an arbitrary number of variables into mysqli query you will need an argument unpacking operator. It will make the operation as simple and smooth as possible. For … Read more

So, for example: $sex = ‘male’; $s = $dbh->prepare(‘SELECT name FROM students WHERE sex = :sex’); $s->bindParam(‘:sex’, $sex); // use bindParam to bind the variable $sex … Read more
