我用这个html标记对一些数据进行排序

<div class="row">
<div class="col-xs-2">
  <img src="images/member-schools/ms1.jpg" class="img-responsive">
</div>
<div class="col-xs-4">
  <h4>American International School - East</h4>
</div>
<div class="col-xs-2">
  <img src="images/member-schools/ms2.jpg" class="img-responsive">
</div>
<div class="col-xs-4">
  <h4>Dover American International School</h4>
</div>

我从我使用的可重复组元数据库中提取数据CMB2

这是注册的metabox的代码

function schools() {

// Start with an underscore to hide fields from custom fields list
$prefix = \'schools_\';

/**
 * Repeatable Field Groups
 */
$schools= new_cmb2_box( array(
    \'id\'           => $prefix . \'metabox\',
    \'title\'        => __( \'schools\', \'cmb2\' ),
    \'object_types\' => array( \'page\', ),
    \'show_on\'      => array( \'key\' => \'id\', \'value\' => 6 ),
    \'closed\'     => true,
) );

$group_field_id = $schools->add_field( array(
    \'id\'          => $prefix . \'field\',
    \'type\'        => \'group\',
    \'options\'     => array(
        \'group_title\'   => __( \'Slide {#}\', \'cmb2\' ), // {#} gets replaced by row number
        \'add_button\'    => __( \'Add Another Slide\', \'cmb2\' ),
        \'remove_button\' => __( \'Remove Slide\', \'cmb2\' ),
        \'sortable\'      => true, // beta
    ),
) );


$schools->add_group_field( $group_field_id, array(
    \'name\' => __( \'Photo\', \'cmb2\' ),
    \'id\'   => \'photo\',
    \'type\' => \'file\',
) );

$schools->add_group_field( $group_field_id, array(
    \'name\' => __( \'Name\', \'cmb2\' ),
    \'id\'   => \'name\',
    \'type\' => \'text\',
) );}

我通过这个代码提取数据

$schools = get_post_meta( get_the_ID(), \'schools_field\', true );

其中$schools是一个数组，其中包含每个条目的图像和标题，我可以通过循环提取值。我的问题是如何添加<div class="row"> 该数组中的每两个项，因为我需要为每两个条目对应一行

编辑：var\\u转储结果

array(3) {
    [0] => array(3) {
        ["photo_id"]    => string(2) "89"
        ["photo"]       => string(56) "http://localhost/NCSR/wp-content/uploads/2015/06/ms3.jpg"
