Bug Type: Arrays related
PHP Version: 4.3.0-dev
New Comment:
IMO this is not a bug. Foreach works virtually like while + each
combination, with a few exceptions such as not requiring a reset()
prior to execution since it does not care about the current position in
the array.
As far as current(), next() and simular are concerned,
while (each($arr)); == foreach ($arr as $v);, once the loops are
complete current() will return FALSE. This IMO is a consistent
behaviour and is definately not a bug. I believe this is merely a
documentation issue.

foreach essentially REMOVES the array pointer alltogether on the
original array.
$arr = array('a','b'); foreach ($arr as $v); var_dump( current($arr)
);
$arr = array('a','b'); foreach ($arr as $v); reset($arr); var_dump(
current($arr) );
Results:
bool(false)
string(1) "a"
Using key() instead of current() results in NULL instead of false.
Where did the pointer go?
Conclusion:
Either foreach() has a feature that removes the array pointer from the
original array or it's a bug. If it's seen as a feature please explain
why so it can be documented.

try 1.:
$var[] = "1";
$var[] = "2";
foreach($var as $test)
{
echo $test;
}
reset($var);
echo current($var);
output -> 12
then try:
$var[] = "1";
$var[] = "2";
//reset($var);
foreach($var as $test)
{
echo $test;
current($var);
}
echo current($var);
output -> 121
this should be the output of the first script too?
Greetings lunepi
