Question

我正在尝试从每个更改为foreach，但是我无法使其正常工作。

我不断收到错误消息，指出PHP Parse错误：语法错误，意外的'）'，但没有意外的'）'吗？???

感谢您的帮助！

    // Splits textarea lines into an array.
    $newEntry = explode("\n",$txtarea);

    // Obtain the number of new entries.
    $x = 0;
    while (each($newEntry)) {
        $x++;
    } 
    reset($newEntry);

//---------------------------------------------------

    if ($_POST['groups']) {
        while (list ($x_key, $x_gid) = each ($_POST['groups'])) {
            $groupsql = "INSERT INTO " . TABLE_GROUPS . " VALUES ($id,$x_gid)";
            runQuery($groupsql);
        }
    }

这就是帖子中的内容

Array ( [id] => 44 [lastname] => Anderson [firstname] => John [middlename] => William [address_zip_0] => 9922 
[nickname] => Will [address_state_0] => Denver, CO [x_gid] => 123T [pictureURL] => pixtest.jpg 
[address_type_0] => testtype [address_primary_select] => test field address primary [address_line1_0] => 2 [address_city_0] => denver
[address_phone1_0] => 111-222-3333 [address_email] => test@test.com [address_phone2_0] => 999-888-7777 [status2] => [notes] => test 1122 
[address_websites] => www.test.com [address_additionaldata] => [groups] => Array ( [0] => 55 ) [address_type_1] => [address_line1_1] => 
[address_line2_1] => [address_city_1] => [address_state_1] => [address_zip_1] => [address_phone1_1] => [address_phone2_1] => [addnum] => 1 )

if ($_POST['groups']) {
        while (list ($x_key, $x_gid) = each ($_POST['groups'])) {
            $groupsql = "INSERT INTO " . TABLE_GROUPS . " VALUES ($id,$x_gid)";
            runQuery($groupsql);
        }
    }

已转换为使用foreach()

if ($_POST['groups']) {
        foreach($_POST['groups'] as $g) {
            $groupsql = "INSERT INTO " . TABLE_GROUPS . " VALUES ({$_POST['id']},$g)";
            runQuery($groupsql);
        }
    }

注释：

-巨大的安全性问题，原始帖子值会像这样进入db

PHP 7.2不推荐使用foreach不起作用
