Cayte, Hello again! >My web surfing showed that ZEND( part of PHP ) can >make calls to C programs like CIFLIB but the may need >to be recompiled with ZEND stuff. Hmmm... interesting piece of info you've got there. Haven't used Zend yet, have you? There are criticisms of PHP being unsuitable for computationally-intensive tasks because it is an interpreted language. Do you think the Zend compiler is the answer to this? Does it produce code whose speed is comparable to that produced by a C/C++ compiler? Cheers!
