我已经阅读了很多关于从数组中删除重复对象的主题,更重要的是,删除了std类对象。我的问题是,似乎没有一致意见,在进入演出时使用哪种方法更好。大多数问题都是以重复的形式提出来的,主要是这个问题
看起来好像两个流行的方法是array_unique()
和foreach
循环,然后有两三个其他没有提到的方法
不幸的是,我的开发站点是为WordPress设置的,只需要很小的测试安装,所以当涉及更大的数据集时,我无法真正运行有关性能的测试。
让我们举个例子:( 注意: 这只是一个小数组,可以包含数百个标准对象)
Array
(
[0] => stdClass Object
(
[term_id] => 1
[name] => First term
[slug] => first-term
[term_group] => 0
[term_taxonomy_id] => 1
[taxonomy] => category
[description] => This is the first term
[parent] => 0
[count] => 2
)
[1] => stdClass Object
(
[term_id] => 2
[name] => Second Term
[slug] => second-term
[term_group] => 0
[term_taxonomy_id] => 2
[taxonomy] => category
[description] =>
[parent] => 0
[count] => 2
)
[2] => stdClass Object
(
[term_id] => 1
[name] => First term
[slug] => first-term
[term_group] => 0
[term_taxonomy_id] => 1
[taxonomy] => category
[description] => This is the first term
[parent] => 0
[count] => 2
)
[3] => stdClass Object
(
[term_id] => 2
[name] => Second Term
[slug] => second-term
[term_group] => 0
[term_taxonomy_id] => 2
[taxonomy] => category
[description] =>
[parent] => 0
[count] => 2
)
)
基于上面的链接问题,一般情况下,基于性能和资源管理,这将是删除重复项的最佳选择
