Once upon a time, a long time ago... require would ONLY read and parse the file one time, so whatever was in there at the first 'require' would get parsed once, and, inside of a loop, pasted multipel times. include would read/parse the file on each iteration of a loop. That got changed in PHP3 or so, because A) nobody understood it, and B) nobody really used it much anyway. When it did get chagned, it was decided that 'require' should be more forceful than 'include' so one should error, and one should warn. There are DEFINITELY times where include more than once is good. Suppose you have the body of a <TR><TD>...</TD></TR> in an include file, and want to include it many times, with different values. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
