PHP Json解码数组未列出

Question

我正在尝试在Wordpress中自定义插件，编写了代码以列出从DB中获取的数据，在Json解码数组被列出之后，但是我尝试使用for和for每个循环，因为两者都没有列出没有显示错误，只是空白。

Wordpress页面模板-

<?php
/**
 * Template Name: List Guide
 */
get_header();
?>
<?php

$query = $wpdb->prepare( 
    "SELECT
       post_content
    FROM 
        wp_posts
    WHERE 
        ID = 7
    ", 
    $ID
);

$string = $wpdb->get_var( $query );

$someArray = json_decode( $string );
print_r($someArray);
die;




 echo  $count = count( $someArray ); 

for ( $i = 0; $i < $count; $i++ ) { ?> 

     <?php echo $someArray->locations[$i]->title; ?> 

<?php } ?>



<?php
get_footer();
?>

输出

已解决

要调用的数组的格式为-

foreach ($someArray['levels'] as $arr){ 

       foreach ($arr['locations'] as $locationarr){ 
            echo $locationarr['title']
       }
}
