only if:
function hello() {
global $sql;
$sql = 'select * from table';
}
or
function hello() {
global $MySpecialSQLInstructionForAnyStrangePurpose;
$sql = 'select * from table';
$MySpecialSQLInstructionForAnyStrangePurpose = $sql;
}
if it isn't global (or set any other global var) you cannot get the value...
(long name, to prevent confusions with other programs that use this
function)
but it is not advised for anything
best regards
