php - 需要对 foreach() 的结果进行分组

问题描述

foreach ($mgrAccounts as $mgrAccount) {
    $mgrAccNames  = $mgrAccount['account_name'];
    $userAccNames = $userRow['account_name'];
    $userAccNames = explode(',', str_replace(['{', '}', '"'], "", $userAccNames));
    $mgrAccNames  = explode(',', str_replace(['{', '}', '"'], "", $mgrAccNames));
    $accounts     = array_intersect($userAccNames, $mgrAccNames);

    if (!empty($accounts)) {
        $tableStr .= "<tr>";
        $tableStr .= "<td><select name='selectAccounts' id='selectAccounts'>";
        foreach ($accounts as $account) {
            $tableStr .= "<option>{$account}</option>";
        }
        $tableStr .= "</select></td>";
        $tableStr .= "<td><a href='/reset_password.php'>Password Reset</a></td>";
        $tableStr .= "</tr>";
    }
}

我需要能够将每个帐户的下拉列表作为其中的一个选项。目前，它正在为每个帐户创建一个新选项。如何将所有内容组合在一起以放入选项下拉列表中？

解决方案

只需在循环外打开和关闭您的桌子

$tableStr .= "<tr>";
$tableStr .= "<td><select name='selectAccounts' id='selectAccounts'>";
foreach ($mgrAccounts as $mgrAccount) {
    $mgrAccNames = $mgrAccount['account_name'];
    $userAccNames = $userRow['account_name'];
    $userAccNames = explode(',', str_replace(['{', '}', '"'], "", $userAccNames));
    $mgrAccNames = explode(',', str_replace(['{', '}', '"'], "", $mgrAccNames));
    $accounts = array_intersect($userAccNames, $mgrAccNames);

    if (!empty($accounts)) {


         foreach ($accounts as $account) {
             $tableStr .= "<option>{$account}</option>";
         }


     }
}
$tableStr .= "</select></td>";
$tableStr .= "<td><a href='/reset_password.php'>Password Reset</a> 
</td>";
$tableStr .= "</tr>";
