PHP use current function in foreach [duplicate]

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 ? You're effectively asking about the internals of foreach (in what way and when it advances the pointer - or not). — AD7six

if you want the output to be 12345:

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

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