There were other semantic differences between the two as well, such as return values etc. Performance appears to now be pretty much the same; you can return values with include() now, and so forth and so on. BTW, require() will fail in a completely different way from include() when it can't find the target file. include() will simply return a false value, whereas require() will spit out a great big 'Fatal error' and halt script execution. -- +----------------------------------------------------------------+ |Torben Wilson <torben@php.net> Netmill iTech| |http://www.coastnet.com/~torben http://www.netmill.fi| |Ph: 1 250 383-9735 torben@netmill.fi| +----------------------------------------------------------------+
