Issue with PHP Extensions

comer_97

I'm trying to use a php extension php_yaz.dll

I've added it to the php.ini, it's in the extensions directory, the extensions directory is set correctly.

but i keep getting the following error when i do a phpinfo();

PHP Warning: PHP Startup: Unable to load dynamic library 'C:\PHP5\ext\php_yaz.dll' - The specified module could not be found. in Unknown on line 0

To confuse matters I'm using PHP 5.2.6 on a PLESK set up.

any ideas how to get over this?

thanks

Windows, yes?

Presuming that the file 'C:\PHP5\ext\php_yaz.dll' does exist, then it's most likely a permissions issue.

If this is an IIS server, try giving the user IUSR_<HOSTNAME> read/execute access to the above file/folder, where <HOSTNAME> is the name of the server.

Don't know much about PLESK - there might be custom users and the like set up. Basically, your server runs as a particular user. This user needs read/execute access to the extension.

It is Windows, it is IIS. I reset the permissions and there was no change.

It's a PECL extension, is there a special way to "install" those extensions for use?

This may sound stupid but I had a hard time enabling SSL because of a really stupid mistake I was making: PHP (at least the one I downloaded and installed) has TWO .ini files, one production and one development. Make sure you are editing the right one

i'm definitely editing the right one. I uncomment the php_yaz extension and the error appears, uncomment it and it's gone again.

Can you post your ini. file here.

There are two possible causes
1) PHP 5 includes an old version of php_yaz

Apparently an updated version is here : http://ftp.indexdata.dk/pub/yaz/win32/

Disclaimer : I haven't downloaded, virus-checked or verified the above link

2) Secondly, there's a dependency on yaz.dll, which would need to be in the available path

You must use YAZ.DLL with version 2.0.13 or later.

The YAZ.DLL version that is shipped with
php-5.0.5-win32.zip is version 1.9.1 and does not work.

YAZ.DLL is part of
http://ftp.indexdata.dk/pub/yaz/win32/
.. when installed copy yaz.dll from yaz\bin to a location in your path
(\winnt\system32 or similar).

I've updated the php_yaz and the yaz.dll is installed and seems to be working,

here is an extract from my php.ini (for security reasons)

;;;;;;;;;;;;;;;;;;;;;;;;;
; Paths and Directories ;
;;;;;;;;;;;;;;;;;;;;;;;;;

; UNIX: "/path1:/path2"
;include_path = ".:/php/includes"
;
; Windows: "\path1;\path2"
;include_path = ".;c:\php\includes"
include_path = ".;c:\program files (x86)\yaz"


extension_dir ="C:\SWSoft\Plesk\Additional\PleskPHP5\ext"

extension=php_yaz.dll

murphaph

My extension_dir has the slashes the other way round (windows):

extension_dir = "C:/server/php/ext"

Also, are you sure the .dll is actually in

C:\SWSoft\Plesk\Additional\PleskPHP5\ext

And I don't understand why your include path points to programmes? Mine points to PHP packages, which are (in my case) in my PEAR directory.

comer_97

I had the include going to the program files because i was clutching at straws.

The file is definitely there and i've changed the direction of the slashes and it still doesn't work.

It's a 64Bit server but I'm not sure that is the issue.
