When you include a file from within a function, the included code is executed in the scope of that function. Thus, when you include t1.php from Test2(), $T=1 is executed in the scope of Test2(), and does not become a global variable. For that reason, global $T inside Test() does not attach to this variable. ------------------------------------------------------------------------ [1999-08-30 10:25:02] lemming@k332.feld.cvut.cz It may be just "feature", but it is not documented to behave so: If I include file within a function and that file declares global variables, they are not really global: file t1.php: <? $T=1; function Test() { global $T; echo "T=$T\n"; } Test() ?> file t2.php: <? function Test2() { include('t1.php'); } Test2(); ?> 'php t1.php' gives T=1 'php t2.php' gives T= it is (unset). If I define T global in Test2(), it works - but it requires Test2 to know which global variables (configuration etc...) Test() uses...
