When we open this url : http://localhost/index.php/test=2

Yep index.php/test=2 not index.php?test=2

Apache open the page index.php one time for every broke link he find in the index.php page.  Example :

<?PHP
  // Simple PHP test page
?>
<HTML>
<TITLE>Simple PHP test page</TITLE>
<BODY>
  <P>Simple PHP test page</P>
  <IMG SRC="image1.gif"><br>
  <IMG SRC="image2.gif"><br>
  <IMG SRC="image3.gif">
</BODY>
</HTML>
<?

  // Keep a log

  /* Log table

CREATE TABLE `simple_log` (
  `sl_time` BIGINT UNSIGNED NOT NULL,
  `sl_url`  VARCHAR(255) NOT NULL
) comment = 'Utilise pour tester le bugs de anikin index/id=2'

  */

  // Current time
  $now = time();

  // Database configuration
  $host     = 'localhost';
  $username = '';
  $password = '';
  $database = '';

  // Open a database connection
  $linkd = mysql_connect($host, $username, $password);
  mysql_select_db($database, $linkd);

  // Insert a log
  $sql = "INSERT INTO simple_log (sl_time, sl_url) VALUES ('$now', '$REQUEST_URI')";
  mysql_query($sql, $linkd);

  // Close the database connection
  mysql_close($linkd);
?>

Images are broke because the path http://localhost/index.php/image1.gif does not exist.  In this case, Apache open 4 times the page index.php.

Here the listing of the log table :

sl_time    sl_url
1005924055 /index.php/test=2
1005924055 /index.php/image1.gif
1005924055 /index.php/image2.gif
1005924055 /index.php/image3.gif

We have the same problem on 3 differents servers.

Compilation script :

'./configure' '--with-mysql=/virtual/mysql' '--enable-bcmath' '--with-gd' '--with-dbase' '--with-curl' '--with-xml' '--with-pgsql=/virtual/postgres/' '--with-imap' '--with-apxs=/virtual/apachedev/bin/apxs'

Apache version :

1.3.20

Php version :

4.0.6 and 4.2.0-dev

erm, ofcourse this doesn't work. / is not a valid URL separator.
Ask for support questions on the php-general@lists.php.net mailinglist.
Not a PHP bug > Bogus.

still not a php problem, *and* intended behaviour

if only part of a URL path exists on the server
and points to a file (not directory) 
the web server will call that file and pass
the rest of the URL as $PATH_INFO

so /index.php/test=2 calls /index.php with $PATH_INFO="test=2"

for <IMG SRC="image1.gif"> the browser will 
strip of what it thinks to be the filename
(as it does not know anything about the server
file system), that is anything after the last 
'/', ending up with "/index.php/", and adds
the relative path from the src attribute
so requesting "/index.php/image1.gif"
which is again treated by the webserver as
a request to /index.php with $PATH_INFO
="image.gif" this time

Thanks you for your reponse.  I will post a question on 
php-general@lists.php.net for a solution to block that.
