这个dr_in_array代码在php8下有什么问题？我PHP7.4换成8.0后，提示系统故障了

{loop $zbhbq $i $c}        
    <div class="col-sm-3 col-md-2">
 {php $data = \Phpcmf\Service::C()->get_attachment($c.file);}
 {if dr_in_array($data.fileext, array(jpg,gif,png))}
     <img layer-pid="{$i}" width="100" height="100" layer-src="{dr_get_file($c.file)}" src="{dr_thumb($c.file, 100, 100)}" alt="{$c.title}">
 {else}
     <img layer-pid="{$i}" width="100" height="100" layer-src="{THEME_PATH}assets/images/ext/{$data.fileext}.png" src="{THEME_PATH}assets/images/ext/{$data.fileext}.png" alt="{$c.title}">
 {/if}
 <div class="caption">
     <p><a href="{dr_down_file($c.file)}">{$c.title}</a></p>
        </div>
    </div>       
{/loop}
