Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to
report
a bug at http://bugs.php.net/how-to-report.php
Using key/next/prev/etc. in foreach() is unsupported. (foreach does an
internal reset() in it too!)
And using key() in foreach is pretty useless since it provides that
with syntax foreach($arr as $key => $val)

Description:
------------
key function within foreach array does not start from the very
beginning of the array instead it starts from the 2nd element
Reproduce code:
---------------
$courses= array(
1=>"test",
2=>"test2",
3=>"test3"
);
echo key($courses)."\n";
foreach($courses as $key=>$course){
echo $key ." ". $course."\n";
}
reset($courses);
echo "\n";
echo key($courses)."\n";
foreach($courses as $course){
echo key($courses) ." ". $course."\n";
next($courses);
}
Expected result:
----------------
1
1 test
2 test2
3 test3
1
1 test
2 test2
3 test3
Actual result:
--------------
1
1 test
2 test2
3 test3
1
2 test
3 test2
test3
