Foreach与list-each在PHP中

Question

Is there any difference in the following methods?

$fruit = array(
    'a' => 'apple',
    'b' => 'banana',
    'c' => 'cranberry'
);

// List-each method
reset($fruit);
while (list($key, $val) = each($fruit)) {
    echo "$key => $val
";
}

// foreach method
foreach ($fruit as $key => $value) {
    echo "$key => $val
";
}

list start iteration from current element whereas foreach start from the first element.

In case you've already iterated the array, list will start from the next element from the previous iteration. You need to reset the array if you want to iterate from the first element.
