SYMPTOMS AND SETUP
------------------
For anyone having problems enabling the PHP openssl extension on WINDOWS.
I uncommented: extension=php_openssl.dll and installed the latest versions of ssleay.dll and libeay.dll in <windows>\system32.
When I restarted my web server and examined phpinfo(), there was no "openssl" headed section (although there were references to openssl in other sections).
I also found this error in my web server logs (<apache dir>/logs/ssl.log and <apache dir>/logs/access.log).
PHP Warning: PHP Startup: Unable to load dynamic library 'C:\\Program Files\\PHP\\ext\\php_openssl.dll' - The operating system cannot run %1.\r\n in Unknown on line 0
I have PHP 5.2.6 running on Apache 2.2.3 for Windows.
CAUSE
-----
This was caused by PHP picking up the WRONG VERSIONS of libeay.dll and ssleay.dll, which were present in multiple locations on my computer.
When any application attempts to use a dll file in windows, the system searches for this file using the following order:
1. The directory from which the application loaded.
2. The windows\system32 directory.
3. The windows\system directory.
4. The windows directory.
5. The current directory.
6. The directories that are listed in the PATH environment variable.
(http://msdn.microsoft.com/en-us/library/ms682586.aspx)
For PHP running under Apache, the application directory is <apache dir>\bin and NOT <php dir>. PHP was finding OUT OF DATE versions of libeay.dll and ssleay.dll in <apache dir>\bin (probably installed when I enabled SSL support in my web server). Because of this, the latest versions in windows\system32 were never reached.
NOTE: Although my problem was caused by an Apache2 specific configuration, I can imagine others might face this problem if, say, they install the openssl dlls in the PHP directory and add this directory to the PATH. I haven't checked it but I would imagine if another directory in the path contains outdated openssl dlls and this is listed before the PHP directory, a similar situation would occur.
SOLUTION
--------
Either replace the dlls in the first location on the search order, or, as I did, you can install the latest openssl dlls in the the windows system32 directory and just rename to .old the ssleay.dll and libeay.dll files in the search order locations before windows\system32.
Hope that helps others who might be stuck with this.
Mark.
Установка
To use PHP's OpenSSL support you must also compile PHP --with-openssl[=DIR].
Замечание: Note to Win32 Users
In order for this extension to work, there are DLL files that must be available to the Windows system PATH. For information on how to do this, see the FAQ entitled "How do I add my PHP directory to the PATH on Windows". Although copying DLL files from the PHP folder into the Windows system directory also works (because the system directory is by default in the system's PATH), this is not recommended. This extension requires the following files to be in the PATH: libeay32.dll
Additionally, if you are planning to use the key generation and certificate signing functions, you will need to install a valid openssl.cnf file on your system. As of PHP 4.3.0, we include a sample configuration file in our win32 binary distributions. PHP 4.3.x and 4.4.x has the file in the openssl directory. PHP 5.x and 6.x has the file in the extras/openssl directory. If you are either using PHP 4.2.x or missing the file, you can obtain it from » the OpenSSL binaries page or by downloading a recent PHP release. Be aware that Windows Explorer hides the .cnf extension by default and says the file Type is SpeedDial.
PHP will search for the openssl.cnf using the following logic:
- the OPENSSL_CONF environmental variable, if set, will be used as the path (including filename) of the configuration file.
- the SSLEAY_CONF environmental variable, if set, will be used as the path (including filename) of the configuration file.
- The file openssl.cnf will be assumed to be found in the default certificate area, as configured at the time that the openssl DLL was compiled. This is usually means that the default filename is c:\usr\local\ssl\openssl.cnf.
In your installation, you need to decide whether to install the configuration file at c:\usr\local\ssl\openssl.cnf or whether to install it someplace else and use environmental variables (possibly on a per-virtual-host basis) to locate the configuration file. Note that it is possible to override the default path from the script using the configargs of the functions that require a configuration file.
