how to clear the query string in PHP.

Question

How to Clear the Query string.

my query string is "index.php?name=sugumar&id=49"

using meta tag I redirect the same page. that time the query string values are not cleared. for that I have used.

Request.QueryString[1] = string.Empty;

but it shows the error.

syntax error, unexpected '[' in /home/sugumar

Then I used

Request.QueryString.Clear();

it shows the error

Call to undefined function Clear() in /home/sugumar

how to solve this problem? I want to clear the query string values before the meta tag redirect the page.

Answer 1

If you are using meta refresh you can not clear the query string.

I would suggest using the header() function in php to redirect instead

header("Location: index.php");

Answer 2

Try:

unset($_SERVER['QUERY_STRING']);

Other possibility is to simply not specify the query string values when you are redirecting:

header('LOCATION: page.php');

Or

<form action="<?php $_SERVER['PHP_SELF']?>">
<form action="page.php">

If that's how you are doing it.
