Answer 1

Try below code:

header('Location: url..?success=1');

Call full url in header function

or

Use jQuery function to redirect to a page

window.location

Answer 2

有技巧，在<?php之后的第一行中使用ob_start（）

Answer 3

Always remember if you are going to redirect to any page then you should not print anything before that otherwise you will get error something like header already sent....just remove

 echo "redirecting to";

before header function

check this code

<?php
    if(isset($_GET['success']) && empty($_GET['success'])){

        $msg= "You Have Been Registered!";
        echo $msg;
        }
    else{
        if(empty($_POST) === false && empty($errors) === true){
        $register_data = array(
            'user_name' => $_POST['username'],
            'password' => $_POST['pass'],
            'email' => $_POST['email'],
            'mobileno' => $_POST['cell'],
            'gen' => $_POST['gen'],
            'first_name' => $_POST['firstname'],
            'last_name' => $_POST['lastname']
        );
        register_user($register_data);

        header("location:../../core/Admin/registrationform.php?success");
            exit();
        }else if(empty($errors) === false ){
            echo output_errors($errors);
        }

    }
        ?>


    </div>
  <form  method="post" action="">

            <label>First Name*</label> <input type="text" name="firstname"/> 
            <label>Last Name</label> <input type="text" name="lastname"/>  
            <label>Gender*</label> <input type="text" name="gen"/>  
            <label>User Name*</label> <input type="text" name="username"/> 
            <label>Email*</label> <input type="text" name="email"/>
            <label>Mobile No* (Must Be Given)</label> <input type="text" name="cell"/>  
            <label>Password*</label> <input type="text" name="pass"/>  
            <label>Confirm Password*</label> <input type="text" name="confirmpass"/>
             <label>Write The Answer Of* :</label> <input type="text" name="ans"/>
