<p>在这个数组输出中，我如何计算类型的数量？或者更好的是，如何在计算时排除additional_data？</p> <pre class="brush:php;toolbar:false;">Array ( [124] =&gt; Array ( [type] =&gt; 0 [value] =&gt; 4 Pack [label] =&gt; 4 Pack ) [125] =&gt; Array ( [type] =&gt; 0 [value] =&gt; 6 Pack [label] =&gt; 6 Pack ) [126] =&gt; Array ( [type] =&gt; 0 [value] =&gt; 12 Pack [label] =&gt; 12 Pack ) [additional_data] =&gt; {"swatch_input_type":"text","update_product_preview_image":"1","use_product_image_for_swatch":0} )</pre> <p>尝试过 <code>count(array_column($swatchLists, 'type'));</code></p> <p>但输出为0</p>

$countResult = array();

foreach( $swatchLists as $item ){
    if( isset($item['type']) == false ){
        continue; // 排除不包含'type'的数组
    }
    $type = $item['type'];
    if( isset($countResult[$type]) ){
        $countResult[$type]++;
    }else{
        $countResult[$type] = 1;
    }
}
var_dump($countResult);
