    PHP stopped working on with IIS

    Hi

    I have a server running PHP 5.2.3 Isapi module with 64 bit IIS 6 on a windows 2003 server.

    This has been working fine for several weeks.

    Overnight, it has stopped processing php, it will still display html pages but php pages are just rendered as an html page header and no content, even a simple hello_world script that just shows a couple of thumbnails and then runs phpinfo();. There have not been any changes to code or config overnight (that I know of).

    I've looked at what I would consider the usual stuff and just can't see what's going on. The windows logs arent showing anything useful.

    Has anybody else seen this? or can somebody tell me where I might find some useful information to get the server back to normal.

    Thanks

    Paul

      You checked the server error logs?

          Hi

          Yes went through system, application and security logs. Nothing there that matches the time that this happened.

          Do you think it's worth re-installing php on the server ?

          Thanks

          Paul

              Possibly.

              Who else has access to it? The rendering of PHP files is handled through server settings that use the PHP DLLs to parse the code into web pages. Check your configuration for anything with the word "php" in it and see what you find.

                  At the moment, nobody else uses it.

                  I have now re-installed iis6 and re configured to use PHP ISAPI.

                  It is back to exactly what I had before which is when I display a php only page I get...

                  Code:
                  <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML><HEAD>
<META http-equiv=Content-Type content="text/html; charset=windows-1252"></HEAD>
<BODY></BODY></HTML>
                  nothing between the php tags on the page is displayed.

                  Here is the code for my page...

                  Code:
                  <?php
//phpinfo();
session_start();
require 'functions.php';
$sess = session_id();
$this_path =session_save_path();
$this_session = $this_path."\sess_".$sess;
echo $this_session."<br>";
print_r ($_SESSION);
echo "hello world<br>";

dateSelect($sel_day,$sel_month,$sel_year);
echo "<br><br><img src= ../user_images/2/koi_thumbs/2_3_20060919232737_736257985.jpg border=\"0\"></a></center>";
echo "<br><br><img src=../user_images/2/koi_thumbs/2_3_20060919232737_736257985.jpg border=\"0\"></a></center>";
echo "<br><br><img src=../user_images/2/koi_thumbs/test_image.jpg border=\"0\"></a></center>";
echo "<br><br><img src=../user_images/test_image.jpg border=\"0\"></a></center>";
phpinfo();
?>
                  I know in the end this will be simple but right now I just cannot see what's going on.

                      It's not the code you should be concerned about. It's the server configuration. Again, look at the lines in the configuration file that have "php" in them and tell me what they say.

                              And PHP is in c:\php?

                              Try this website: VisualWin.com

                              They've got a lot of resources on IIS.

                                  Hi

                                  Yes, PHP is in c:\php.

                                  I used the installation instructions here...

                                  http://www.peterguy.com/php/install_IIS6.html


                                  It's fixed for now (or more accurately worked around).

                                  I have changed the setup to be CGI rather than ISAPI.

                                  I'll have to sort this out properly at some time but it's back in action for now.

                                  Thanks

                                      Well, as long as it's local, CGI won't hurt anybody. Otherwise, you'll need to deal with that ASAP.

                                          Well, it gets odder and odder.

                                          Today I have reset back from CGI to ISAPI and it works just fine.

                                          There does seem to be something odd and nasty around using 32 bit modules with the 64 bit version of IIS 6. even with the WOW compatibility on and the

                                          cscript %SYSTEMDRIVE%\i netpub\adminscr ipts\adsutil.vb s SET W3SVC/AppPools/Enable32bitAppO nWin64 1

                                          command which is supposed to enable 32 bit and 64 bit modules to be run at the same time.

                                          So I have a work around if / when it happens again which is to change to CGI mode, run a few pages through, restart IIS and then reset back to ISAPI.

                                              I have had the same issue. PHP just stopped working on my server after about 2 weeks of working fine. I tried the cgi solution suggested but that has made no difference. Anyone else with any ideas? Would really appreciate the help

                                                  Hi, just an update on this. Installed an earlier version of php5 (5.1.6) and got the server back up and running. Today the same thing has happened again. No amount of reinstalling seems to be working this time
