PHP Bug Type: Unknown/Other Function
Bug description: Extra null parameter appearing with func_get_args
I have a function that takes a variable number of arguments and uses
func_get_args to retrieve them as an array. In one place when I call this
function with two arguments a third, empty argument is added. As the
function is used to generate SQL 'where' clauses by joing strings with '
and ', this caused a sever problem to my system! I have added an explicit
test for null strings in the function and this has worked round the
problem. I use this function in many places in my code and only this one
call has problems. Here is the function, you can see the work round code I
added.
function dband()
{
$args = func_get_args();
$str = jval(array_shift($args));
foreach ($args as $v)
{
# if ($v != '')
# {
$str .= ' and '.jval($v);
# }
}
return $str;
}
I had another version of this function that tried to use array functions
to achieve this result but I could not get it to work reliably, but for
reasons other than extra arguments.
