我之前有写过类似这个功能，这次写的全一点，高亮显示实现功能也是用到这个$uri=explode('/',$_SERVER['REQUEST_URI']);

我贴一下代码，你们可以参考一下，个人暂时未找到更好的方法，有什么好的方法，可以在下面评论，我们探讨一下。

$uri=explode('/',$_SERVER['REQUEST_URI']);
<?php
					$categories = get_categories("hierarchical=1&taxonomy=video&hide_empty=0");
					$cats=array();
					foreach($categories as $tmpcat){
						if($tmpcat->parent>0){
							$cats[$tmpcat->parent]['child'][$tmpcat->term_id]['name']=$tmpcat->name;
							$cats[$tmpcat->parent]['child'][$tmpcat->term_id]['term_id']=$tmpcat->term_id;
						}else{
							$cats[$tmpcat->term_id]['name']=$tmpcat->name;
							$cats[$tmpcat->term_id]['term_id']=$tmpcat->term_id;
						}
					}
					ksort($cats);
					foreach($cats as $key=>$val){?>
						<li class="cat-item">
							<i class="fas fa-angle-down"></i><a><?php echo $val["name"]; ?></a>
							<ul class="children">
								<?php foreach($val["child"] as $cat){ ?>
									<li class="cat-item">
										<a<?php if (ucwords(str_replace('-',' ',$uri[3])) == $cat["name"] ) {echo ' class="opeth"';}?>><?php echo $cat["name"]; ?></a>
										<?php
										$posts_array = get_posts(
											array(
												'posts_per_page' => 3,

												'tax_query' => array(
													array(

														'field' => 'term_id',

												)
											)
										);
										if ($posts_array){?>
											<ul class="children">

													$youtube = substr(basename(get_field('add_link')),8);

													<li<?php if ($uri[4] == $a ) {echo ' class="opeth"';} ?>>
