php - OpenSSL enabled but not working

Question

I am running Apache 2.2.13 and PHP 5.2.12. Just installed PHP 5.2.12 manually (to have access to all extensions) and enabled OpenSSL. phpinfo() indicates OpenSSL is enabled and running OpenSSL 0.9.8k 25 Mar 2009.

I'm getting this error: PHP Fatal error: Call to undefined function ftp_ssl_connect().

I've seen where the PHP manual suggests 'ftp_ssl_connect() is only available if both the ftp module and the OpenSSL support is built statically into php' and further states that 'you must compile your own PHP binaries' to make it work with Windows.

I have the suspicion that phpinfo() only indicates OpenSSL as being 'enabled' because I have uncommented the line 'extension=php_openssl.dll' and have the correct dlls in the correct folders and the correct path in the environment variables. And perhaps a static build into PHP must be accomplished regardless of what phpinfo() indicates.

I believe the objective of distribution (as described above) is for dynamic extensions, but recompiling (for OpenSSL) is to encode a static extension.

ftp extension is working fine (built into PHP 5.2). I test this with the following code:

$conn_id = ftp_connect($url); $login_result = ftp_login($conn_id, $username, $password); ftp_close($conn_id);

Note that to check ssl, I only change ftp_connect to ftp_ssl_connect. When reaching this line, I get the PHP error above in my Apache error log file.

As the documentation states (quoting what you already quoted) :

Note: Why this function may not exist
ftp_ssl_connect() is only available if both the ftp module and the OpenSSL support is built statically into php, this means that on Windows this function will be undefined in the official PHP builds.
To make this function available on Windows you must compile your own PHP binaries.

You say you installed PHP "manually" ; but this probably still means you used an "official" build from php.net -- which means you have not compiled your own PHP binaries... So, that function is not available.

There is no magic : it seems you'll have to re-compile PHP, using the right configuration options at compile-time, if you want to be able to use that function...

Here's some documentation about that : Build your own PHP on Windows -- but... good luck... i've never heard it was "simple" to compile PHP on windows, actually (it's not that hard on Linux, but Linux is maybe a bit more well suited when it comes to compilation)

A couple of other solutions :

• switching to Linux for your developments (even if it's only using a Virtual Machine) -- but you might still have to recompile PHP to get that (might not be enabled by default)
• just not using that function ; after all, do you know if your hosting service will provide you with it ? (If you can't use it on your production server, no need to use on your development/testing machine)
