PHP5.0.2win32 dont find mysql dll file

Hi!
I have a very frustrating problem!

I have installed php5.0.2 into apache2.0.52 at windows xp, service pack
2.
This works fine, the server is responding, and php answers nicely.
When I install MySQL 4.1.7, I can start the database server, and it works
as it should.
But when I try to get php to recognize mysql, the trouble begins..
Apache tries to load php, but fails with this error message:
PHP Startup: Unable to load dynamic library
'c:\php\extensions\php_mysql.dll' - Can't find the procedure. After that,
apache crashes.

I have the php_mysql.dll in the extensions dir, and the php.ini contains
this line: extension_dir = "c:\php\extensions\"
all according to the install.txt file.
In the windows PATH, there is the 'c:\php;c:\php\extensions'
path.
If I remove the line
extension=php_mysql.dll
everything starts nicely, of course without mysql.

Why can't php find the dll file??

This is beyond my understanding, so please help me!

I can't explain it, but in Windows XP I experienced the same problem with
some of the php extensions.
I finaly got those extensions to work by putting them in C:\WINNT\system32\
folder.
Anyway this was a temporary development environment so I didn't try very
hard to find how to make them work in php\extensions\, but at least it
worked fine from the .../system32 folder.
WinXP is not my usual working environment, so maybe someone will be able to
tell you more... for now you may want to try the system32 folder

Hi Dae,
I tried to put php_mysql.dll in the system32 folder, but it did not help.
I also tried to give 'All' permissions to read all folders and files in the
php directory. I tried to remove the line
extension_dir = "c:\php\extensions\",
but then php defaults to "c:\php5\ext\" or something similar.
It does not s

in the system32 folder at all.

I finally tried to change
extension_dir = "c:\windows\system32\",
but this only generates the same message:
"PHP Startup: Unable to load dynamic library 'c:\windows\system32
\php_mysql.dll' - Can't find the procedure. "

This is so strange..

I fixed it! With a tip from a friend.
He told me to copy libmysql.dll from c:\php to c:\windows, and that solved
everything!

I encountered same problem, but with another extensions, and i solved it by

1. copying all DLLs from ...\PHP\extensions TO ...\Windows\System32;

2. copying all dynamic link libraries from (...)\PHP\dlls\ to (...)\Windows\System32 directory (because DLLs that reside in ...\PHP\extensions rely on DLLS in ...\PHP\dlls\.

I did not have that problem before installing Service Pack 2 on WinXP, and maybe only WinXP SP2 does not load DLLs that are not in System32 folder.
