I am using Apache 2.2 server, PHP 5.3.6 on a Windows 7 OS running on a 64-bit system.
On starting Apache server, this error appears in the apache error log-
PHP Warning: PHP Startup: Unable to load dynamic library 'D:\\php5\\ext\\php_curl.dll' - The specified module could not be found.\r\n in Unknown on line 0
Following are the other extensions mentioned in the php.ini -
extension=php_curl.dll extension=php_gd2.dll extension=php_mbstring.dll extension=php_mysql.dll extension=php_xsl.dll extension=php_memcache.dll
phpinfo() does not show the curl extension loaded, but the others are loaded.
php_curl.dll file is however present in the correct location along with the others -
phpinfo() shows that
extension_dir = D:\php5\ext
So, that also is correct.
Some more details
I am a new member in this team and I had setup Apache, PHP separately on this Windows 7 system and everything was working fine. Our project needed a lots of httpd conf changes, so I was asked to simply overwrite the httpd conf file with the team's current version. I did the same and just changed the ServerName, ServerAdmin etc. I also copied their PHP installation directory. Everything other than this extension is working fine.
