I mean it's fairly easy to write it. thought about tthat one myself.... doesn't work: no, cause you cannot get the correct __FILE__ and __LINE__ if you implement it in php! also i implemented dynamic evauation of the expression: assert_options(ASSERT_ACTIVE,1); assert(0); assert('count($hallo) == 0'); // if ASSERT_ACTIVE is 0 this will NOT be evaluated! i see if i can write the docs later today... also see: <? function myassert($fname,$lineno,$myeval) { printf("\nmyassert failed in $fname:$lineno \"$myeval\"\n"); } assert_options(ASSERT_CALLBACK,"myassert"); assert_options(ASSERT_BAIL,1); assert_options(ASSERT_WARNING,1); $entries=array(); assert('count($entries) == 1'); assert('$a == 0'); ?> > > I don't know if you'd need logging or not, we already have a function > for that. > > -Andrei > * We reason deeply, when we forcibly feel. * > > Thies C.
