Subject: dl and extension directive in php.ini
From: zaunere@yahoo.com (Hans Zaunere)


Hello,

I'm hearing some conflicting reports and I'd like to see other's thoughts on
this.

Loading an external module using dl() at runtime obviously loads the module
per request (ie, performance hit).

On the other hand, which I believe is the recommended method anyway, is using
the extension= directive in php.ini.  While this is still a dynamic module
load, it should only happen once; for instance when the Apache child process
is forked.  However, while reading some Zend API docs I began to doubt this,
so I'm interested in some confirmations.

Basiclly, I'm of the understanding that dl() is 'bad' anyway, so I guess the
question really is: when specifying a dynamic module (.so) from php.ini, does
it get loaded per request or at process creation time?

Thanks,

H
