Description:
------------
After installing PHP 5.0.1 (and latest CVS) I get "Cannot redeclare <functionname/classname> (previously declared in <filename>)" errors at random.

Then after a few seconds a window pops up with a dllhost.exe error. Saying somthing like "Memory could not be read". And my IIS chrashes.

All this do not happen every time i load the page only sometimes.

This did not happen in PHP 5.0.0.

Im running PHP as ISAPI. 

Actual result:
--------------
Fatal error: Cannot redeclare db_connect() (previously declared in D:\HTDocs\BEC\includes\database.inc.php:8) in D:\HTDocs\BEC\includes\database.inc.php on line 10

It looks like I dont get the error if I turn off ISAPI caching.
 [2004-09-27 09:34 UTC] kj at legalizer dot dk
With PHP 5.0.2 and IIS 6.0 I get the same error (without the crash) even if I turn off ISAPI caching.

The IIS 6.0 problem is on a Windows 2003 server.

i got the same problem with php 5.1.2 on MS IIS 6.0 on a windows 2003 Server.
"Cannot redeclare ..." appears at random, but the file is only included once.

This is happening in 5.2.5 (also win2k3-sp2, iis6, isapi). Since most of the pages in the application I'm testing are fairly complex, I created a test script with a single function to do some basic math. After browsing around a bit in the main application (and seeing the "redeclare" bug, probably 15% of the page loads, with random functions being the culprit even when reloading the same page), I pointed at my test script and refreshed once or twice and got: PHP has encountered an Access Violation at 01B09F7E

The main application is heavy in SOAP.

I am brand new to PHP. Here are my particulars with this problem. I am running:

Windows XP 5.1.2600 Service Pack 2 Build 2600
IIS 5.1
PHP 5.2.5 installed from php-5.2.5-Win32.zip
  defined to IIS using php5isapi.dll
MySQL 5.0.51a Win32
phpMyAdmin 2.1.4

I built a test page that only contains phpinfo(). It loads fine.

When I load phpMyAdmin, I get the login page. After supplying my user name and password, I get:

Fatal error: Cannot redeclare pma_ifsetor() (previously declared in D:\My Web Sites\phpMyAdmin\libraries\core.lib.php:38) in D:\My Web Sites\phpMyAdmin\libraries\core.lib.php on line 45

Notice that the previous declaration and the current declaration are in the same file (including the same path) at different line numbers. The fact is that in this file, line 38 is the PMA_ifSetOr() function declaration, while line 45 is then end of the fPMA_ifSetOr function (i.e. the ending "}"):

38 function PMA_ifSetOr(&$var, $default = null, $type = 'similar')
39 {
40     if (! PMA_isValid($var, $type, $default)) {
41         return $default;
42     }
43 
44     return $var;
45 }


One other interesting observation: If I restart IIS and then press F5, the page then loads successfully. Once I get this error, pressing F5 returns the same error until I restart IIS. Then (at least every time so far), the page loads fine.

Having the same problem with 5.1.0 on windows 2003. Is there a solution 
for this problem?
 [2010-03-10 09:38 UTC] eugenio at blux dot org
Same problem (Cannot redeclare functions...) with php 5.2.3 and IIS 6 on windows 2003 Small Business Server. Php in ISAPI.
 [2010-05-08 17:39 UTC] rmac at iki dot fi
I found out one way how this error message can happen: it happens if you declare a 
function with a reserved name. So try changing the name of function to something 
else.
