New Comment:
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?
