use of header()

I want to use header():

header(Location: "file.php")
but want to pass parameters to the php scrip.
how should I write it ???

thanks !

the 'location' is an URL, so do something like:

header('Location: file.php?this=that&foo=bar');

Remember that when quoting text you should consider speed and flexibility :

Using this :

<?php
$name = 'Jacob';
$age = 27;
header('Location: script.php?name=$name&age=$age');
?>

.. would result in heading to the URL "script.php?name=$name&age=$age" and NOT "script.php?name=Jacob&age=27".

Instead you could use :

<?php
header('Location: script.php?name='.$name.'&age='.$age);
?>

Which is "less" readable but faster than :

<?php
header("Location: script.php?name=$name&age=$age");
?>

Which is more "flexible" ...

Note : I'm not trying to start a way here, but it is a problem for most "new" people to PHP.

thanks
