PHP use current function in foreach

Question

$arr = array(1,2,3,4,5);

foreach($arr as $key => $row) {
    echo current($arr);
}

//output is 22222, why?

Why the result is not 12345?

Have you read the docs for [current](http://www.php.net//manual/en/function.current.php) ? You're effectively asking about the internals of foreach (in what way and when it advances the pointer - or not). — AD7six, Jun 24 '14 at 08:36

if you want the output to be 12345:

$arr = array(1,2,3,4,5);

foreach($arr as $key => $val) {
    echo $val;
}
