Question

I’m using the below function to redirect a person after specific task (eg.: after login, after logout, after searching etc.)
code is below:

<?php
class common {
    /* Redirect to another page
     * $url= Url to go
    */
    function redirection($url){
        header("location: $url");
        exit();
    }
    // Some other function below
?>

But now I’m dealing this class with many project of different host (MLM project). I have a problem now. With some server it works as i expected, but in some other server, it’s not redirecting. If i enable error_reporting(E_ALL); i found a notice that headers are already send. So I’m in confusion that what can I do now instead of header() function. Also i tried the below code

<?php
    function redirection($url){
        echo "<div align='center'><a href='$url' target='_top'><img src='../img/proceed.jpg' alt='Proceed>>' align='absmiddle' border='0'></a></div>";
        exit();
    }
?>

But it is not desirable as everybody wants automatic redirection. My servers are windows and linux both. Please help me anyone

Answer 1

well, this situation is very common, then you can simple turn on output buffering (the output will be stored in an internal buffer).

Use ob_start(); in the very first line of your application

<?php
    class common {

        /* Redirect to another page
         * $url= Url to go
         */

        function redirection($url)
        {
          header("location: $url");
          exit();
        }

        // Some other function below

    }

?>


<?php
    ob_start("redirection");

    // Your Common Class Page
    include("Common.php");

     // some code 

    ob_end_flush(); // turn off output buffering
?>
