Question

一个字符串，如下所示：

<ul class="page-sidebar-menu  page-header-fixed page-sidebar-menu-hover-submenu " data-keep-expanded="false" data-auto-scroll="true" data-slide-speed="200">
    @foreach (var menuLevelTest in ViewBag.MenuLevelTest)
    {
        <li class="nav-item start">
            <a href="javascript:;" class="nav-link nav-toggle">
                <i class="icon-home"></i>
                <span class="title">@menuLevelTest.Name</span>
                <span class="arrow"></span>
            </a>
            @if (menuLevelTest.Menu1.Count > 0)
            {
                <ul class="sub-menu">
                    @foreach (var menuLevelTest2 in menuLevelTest.Menu1)
                    {
                        <li class="nav-item">

                            <a href="javascript:;" class="nav-link nav-toggle">
                                <i class="icon-bar-chart"></i>
                                <span class="title">@menuLevelTest2.Name</span>
                            </a>
                    @if (menuLevelTest.Menu2.Count > 0)
                    {
                        <ul class="sub-menu">
                            @foreach (var menuLevelTest3 in menuLevelTest.Menu2)
                            {
                                <li class="nav-item">

                                    <a href="javascript:;" class="nav-link nav-toggle">
                                        <i class="icon-bar-chart"></i>
                                        <span class="title">@menuLevelTest3.Name</span>
                                    </a>
                                </li>
                            }
                        </ul>
                    }
                        </li>
                    }
                </ul>
            }
        </li>

从数据库获取条件字符串

想要转换为数组所以，它可以传入以下语句：

$condition = "['or',['LIKE','name','index'],['=','type',1]]";

Answer 1

你可以简单地使用eval()（不是特定于yii）：

$condition = "['or',['LIKE','name','index'],['=','type',1]]";
eval("\$condition = $condition;");

详细了解eval()。
