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>";
