Bug or not bug

[paullefil]

I have 3 files on my website

tes1.php :
<?php
require_once("t est2.php");

if ($_GET['redirige'] == 1)
{
@header( "Location: http://www.mydomain.co m/test3.php" );
}
else
{
echo "it's test1.php";
}
?>

and test2.php (one file without php code !)

<?php
?>

and test3.php :

<?php
print "it's test3.php";
?>

Now if you load :

http://www.mydomain.com/test1.php

(it's written "it's test1.php")

Now if you load :

http://www.mydomain.com/test1.php?redirige=1

The result is a blank page but normally you will be redirect to
http://www.mydomain.com/test3.php with "it's test3.php" written.

Now in the test1.php file, you delete the ligne
require_once("t est2.php");
So your test1.php file is :

<?php
if ($_GET['redirige'] == 1)
{
@header( "Location: http://www.mydomain.co m/test3.php" );
}
else
{
echo "on affiche test1.php";
}
?>

Now if you load :

http://www.mydomain.com/test1.php

(it's written "it's test1.php")

Now if you load :

http://www.mydomain.com/test1.php?redirige=1

The result is a OK you are redirect to
http://www.mydomain.com/test3.php with "it's test3.phpp" written.

Could you help me, where is the bug ?

Probably a space/newline/something outside <?php ?in test2.php.
Try this in test1.php:
ini_set('displa y_errors',1);
error_reporting (E_ALL);

Which will probably tell you headers are already sent by test2.php

You've got white space before or after your php code in test2.php.

If you were displaying errors, you'd get a message about the headers
already being sent due to this white space.

@header( "Location: http://www.mydomain.co m/test3.php" );

The @ operator removes any possible warning or error message. You'll never
be able to debug properly if you drop it here and there in your code.
Furthermore, what runtime error are you expecting in a call to header()??

Also, sending a header doesn't stop the script execution. I suggest you
append an exit() statement.

The result is a blank page but normally you will be redirect to
http://www.mydomain.com/test3.php with "it's test3.php" written.

Have you enabled error reporting directives in "php.ini". If I recall
correctly, they are:

display_errors = On
error_reporting = E_ALL
