3 to 4 preventing multi - includes

Anon

Hi,
in php3 we could prevent multiple re-definitions of functions in include files that might be included more than once by using constants:

$flag = 'INCLUDE_' . basename(FILE);

if(defined($flag)) { return; }

define($flag,TRUE);

works perfectly in PHP3. In 4, the test of defined()
seems to fail, and we get multiple re-defs of our functions in the included file.

Anyone have any ideas?

kind regards.

Just replace your include() calls with include_once() which is, according to the manual, "similar to the include() statement, with the important difference that if the code from a file has already been included, it will not be included again".

thanks Beth - I guess I have a long night ahead of editing all my
included files to run on PHP4 ...
have found that whilst
basename(FILE) seems have stopped working, I can get
basename(getenv(SCRIPTNAME))
to work under PHP4 to give the same functionality - only have to do a find replace then....
all the best
