Hi

I am experiencing problems when using multi-threaded cURL (libcurl) on PHP.

When I have more than about 5 threads, all subsequent threads fail to
connect. I presume this is because PHP hasn't implemented the
CRYPTO_callback functions to prevent OpenSSL locking.

Following on from this thread about an implementation of libcurl...
http://curl.haxx.se/mail/lib-2004-06/0086.html

Does anyone know how I could implement the CRYPO_callbacks in PHP?

Thanks
Emile
