php 5.0.2 does not load extensions

[aangelo]

Hi all!

my configuration:
- OS: Windows XP
- server: IIS 5.1
- MySQL: 4.1.6 gamma-nt
- php 5.0.2

• installed php 5.0.2 from zip file

• configured C:\windows\php.ini, starting from php.ini-recommended, with options:
  extension_dir = "c:\php\ext" and
  extension=php_mysql.dll

• set %PHPRC% = C:\windows

• added C:\php;C:\php\ext to %PATH%

• configured IIS for .php extension and C:\php\php5isapi.dll

• php libmysql.dll has been copied into C:\Windows\System32

• net-stopped/started IIS

• reset machine

Initially, php worked with MySQL and I executed some queries.
BUT, SUDDENLY, PHP STOPPED WORK:
- Appears the well-known message "PHP Startup: Unable to load dynamic
library 'C:\php\ext\php_mysql.dll' - Impossibile trovare la procedura
specificata."

• I removed the whole php directory and repeated all installation (three
  times), but nothing changed.

• The problem is not specific to php_mysql.dll, but occurs with all
  extensions (e.g. php_oci8.dll)

• MySQL installation has a different libMySQL.dll (1.044 kB instead of 228
  k😎: I tried to replace the php dll with this one, but it doesn't work.

• Adding php5isapi.dll, php5ts.dll, php_mysql.dll to C:\windows\system32 gives no result.

• php.ini is found in fact if I comment again [FONT=courier new]extension=php_mysql.dll[/FONT]
  the message error doesn't display.

I searched over many forum but I cannot find any other suggestion.
Can someone help me?
Thanks!!!
Antonio

Hi,

MySQL:

copy the libmysql.dll that comes with the zip PHP package to system32

Oracle:

You need to install the Oracle client on the PC/Server.

There are some other dlls in the zip package you need to copy to system32 depending on the extension you want to enable. You don't need to copy php_mysql.dll/php5isapi.dll to system32 if extension_dir is set to the correct directory.
