Cannot load extensions

[melchiorus]

I've been using PHP for a long time now on my Windows XP Pro machine and had little problems. Today, I needed to enable a new extension (php_domxml.dll) so I just went into my php.ini and uncommented that line. I restarted apache, however, and got this error:

Warning
Unknown(): Unable to load dynamic library 'C:/PHP/extensions/php_domxml.dll' - The specified module could not be found.

Right off the bat I figured it was a typo or something, but I triple checked all my path names and everything, everything is correct. What is really strange is that I can load some extensions and not others.

In my php.ini file:

; Directory in which the loadable extensions (modules) reside.
extension_dir = "C:/PHP/extensions/"

...

;Windows Extensions
;Note that MySQL and ODBC support is now built in, so no dll is needed for it.
;
;extension=php_bz2.dll
;extension=php_cpdf.dll
;extension=php_crack.dll
;extension=php_curl.dll
;extension=php_db.dll
;extension=php_dba.dll
;extension=php_dbase.dll
;extension=php_dbx.dll
extension=php_domxml.dll
;extension=php_exif.dll
;extension=php_fdf.dll
;extension=php_filepro.dll
extension=php_gd2.dll
;extension=php_gettext.dll
;extension=php_hyperwave.dll
;extension=php_iconv.dll
;extension=php_ifx.dll
;extension=php_iisfunc.dll
;extension=php_imap.dll
;extension=php_interbase.dll
;extension=php_java.dll
;extension=php_ldap.dll
;extension=php_mbstring.dll
;extension=php_mcrypt.dll
;extension=php_mhash.dll
extension=php_mime_magic.dll
;extension=php_ming.dll
;extension=php_mssql.dll
;extension=php_msql.dll
;extension=php_oci8.dll
;extension=php_openssl.dll
;extension=php_oracle.dll
;extension=php_pdf.dll
;extension=php_pgsql.dll
;extension=php_printer.dll
;extension=php_shmop.dll
;extension=php_snmp.dll
;extension=php_sockets.dll
;extension=php_sybase_ct.dll
;extension=php_w32api.dll
;extension=php_xmlrpc.dll
;extension=php_xslt.dll
;extension=php_yaz.dll
;extension=php_zip.dll

The directory C:\PHP\extensions does exist and the file php_domxml.dll is sitting right there. I've tried copying that extension to my C:\WINDOWS\System32 directory (just incase Windows is being stupid again) but it still did not work. Does anyone have the slightest clue what's going on and how to fix it? I'm running PHP 4.3.11 and Apache 2.0.

; Directory in which the loadable extensions (modules) reside.
extension_dir = "C:/PHP/extensions/"

try changing that to

extension_dir = "C:\PHP\extensions"

hope that will help

And remember that in many cases to be able to load one extension you may need to load another one.

Thanks for the help. Changing the path to using backward slashes didn't work, but the second post about needing other dependencies got me searching and I found the answer.

Just for anyone else experience similar issues sometime, here's what I found:

The problem was that I started out with the windows installer version of
PHP 4.3.0 and then just copied the libxml2 and php_domxml from the
windows4.3.0.zip file to their locations. I completely forgot to copy
the other DLL's from the php_install_dir/dlls/ folder to
windows/system32. This solved the problem.

In a nutshell, copy everything from X:\PHP\dlls to X:\WINDOWS\System 32.

Thanks again for all the help.

you'll have to escape backslashes then, you can't use them as you suggested!! However, windows can understand both back-slashes & forward-slashes, so its not that issue!!!
