如何才能获得以同一个单词开头的所有会话？

Question

I have problem with building a cart. How can I get all the sessions that starts with the same word?

Answer 1

$start = 'startingword';
$new_session = array();
foreach($_SESSION as $index=>$value) {

    $temp = explode(' ', $index, 2);
    if($temp[0] == $start) {
        $new_session[$index] = $value;
    }
}

If the starting word is session value and not index, then,

foreach($_SESSION as $index=>$value) {

    $temp = explode(' ', $value, 2);
    if($temp[0] == $start) {
        $new_session[$index] = $value;
    }
}
