Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions. 

Thank you for your interest in PHP.

Works fine for me. (there's something wrong with your system
apparently)

Description:
------------
This bug was postet at apache.org as Bugzilla Bug 26912 but the guys
there told me to post here...



I wrote a small PHP script to display a simple table fetched from MySQL
on my system. The response time from sending a request until the page
is displayed is EXTREMELY slow 5-7 seconds (!) even for tables with
only 27 rows. In this time 

period the hard disk is accessed continously (writing sound). The more
rows are added, the slower it gets (each row ~200ms).



I installed the same script at
(http://akoerni.lima-city-webspace.de/list.php?EinsatzID=1) so you can
get an idea. At this site it works as fast as usual (a 

few milliseconds) if you do not consider request time.



It is **NOT** a database/query issue. MySQL response time is some
milliseconds (tested with MySQL Control Center, mysql.exe, PHP
script).

It is **NOT** a latency issue. (Installed on localhost. Redirected
above mentioned website to my local database resulting in good
performance).



The problem is reproduceable with the following configuration:



Windows 2000 SP4      (AMD 2400+, 512MB)

Apache 2.0.48         (apache_2.0.48-win32-x86-no_ssl.msi)

PHP 4.3.4 AND 5.0.0b4 (php-4.3.4-Win32.zip / php-5.0.0b4-Win32.zip)

MySQL 4.0.17          (mysql-4.0.17-win-noinstall.zip)



Using Apache 1.3.29 on together with PHP 4.3.4 results in good
performance! (It does not work with 5.0.0b4, however). I installed each
version of Apache as service to all users. The httpd.conf is the
default config + 3 PHP specific 

lines. The php.ini is the php.ini-recommended file with adaptions for
the extension_dir and the uncommented line "extension=php_mysql.dll"
(PHP 5).

Reproduce code:
---------------
PHP code for the creation of the HTML table follows:



function xmicrotime($name, $starttime) {

  $now = explode(" ", microtime());

  $before = explode(" ", $starttime);

  $mseconds = $now[0] - $before[0]; 

  $seconds = $now[1] - $before[1]; 

  echo $name . " took " . $seconds . " sec. and " . $mseconds . "
ms.";

}



$i = 0;

$start= microtime();

while ($line = mysql_fetch_array($result, MYSQL_ASSOC)) {

   $i++;

   echo "\t<tr class=\"";

       if ($i%2 == 0) {echo "GERADE";}

         else {echo "UNGERADE";}

   echo "\">\n";



   echo "\t\t<td class=\"datum\">" .$line[Datum]. "</td>\n";

   echo "\t\t<td class=\"zeit\">" .$line[Zeit]. "</td>\n";

   echo "\t\t<td class=\"kanal\">" .$line[Kanal]. "</td>\n";

   echo "\t\t<td class=\"betriebsart\">" .$line[Betriebsart].
"</td>\n";

   echo "\t\t<td class=\"an\">" .$line[An]. "</td>\n";

   echo "\t\t<td class=\"von\">" .$line[Von]. "</td>\n";

   echo "\t\t<td class=\"ereignis\">"
.htmlspecialchars($line[Ereignis]). 

"</td>\n";

   echo "\t\t<td class=\"vermerk\">" .htmlspecialchars($line[Vermerk]).


"</td>\n";



}

xmicrotime("total_time:", $start);

Expected result:
----------------
The script should not take longer than 200ms.
