How to redirect with PHP

  • 772

I have this page.

maximalearning.hardsoft.xyz

What should I do so that every time a user tries to navigate in this way...

maximalearning.hardsoft.xyz/index.php?id=start

It redirects to index.php and so on with the rest of the pages. But it is if there is something after the ".php" not just a "?variable=value"

Thanks.

    As indicated in the comments, having an Apache server, you can use the file .htaccessto define redirects. So what you are looking for would be something like this:

    # Activa el modulo de redirecciones (mod_rewrite)
RewriteEngine On
RewriteBase /

# Si la solicitud incluye un query string, entonces redirecciona borrándolo
RewriteCond %{QUERY_STRING} .
RewriteRule ^(.*)$ $1? [L,R=301]

    The part about activating the redirects module doesn't require much explanation, but I think more information is needed in the other two lines:

    • RewriteCond %{QUERY_STRING} .: this line is a condition, the next line will only be executed if the requested URL includes a query string (the ?name=value part)
    • RewriteRule ^(.*)$ $1? [L,R=301]: this line is more interesting, basically what it says is:
      • redirects the url whatever it is ( ^(.*)$)
      • herself ( $1)
      • without the query string (the one ?after $1; without the ?, the query string will remain in the URL)
      • this will be the last rule executed (indicated by the sign L)
      • it must be redirected with the code 301 (the signal R=301; without this signal, the redirection would be made but no change would be seen in the address bar).

    If you don't want to use it .htaccess, you could do a similar redirect from PHP (although it would be less efficient) by adding this little script to the top of all PHP files that you want to remove their query string :

    // si hay algún elemento en el query string
if (count($_GET) > 0) {
    // redirige a la misma página sin el query string
    header("Location: " . $_SERVER['PHP_SELF']);
}
