$skillsarray = ["php","java","ios","php","php","php","php","java","java","ios"]; 

$cityarray = ["Chennai","Theni","Theni","Mumbai","Chennai","Theni","Chennai","Hyderabad","Theni","Madurai"];

如果我用array_unique为$skillsarray，得到的结果作为array_unique - PHP - 笨

[ “PHP”， “Java” 的， “IOS” 如果我用array_unique

对于$cityarray，得到的结果作为

{ “0”： “奈”， “1”： “与Theni”， “3”：“木MBAI”， “7”： “海得拉巴”， “9”： “马杜赖”}

任何人都可以解释为什么array_unique($cityarray)是生产字典结果呢？

对于这两种情况'array_unique'将返回唯一值的'array'。 –

'array_unique'将不会返回这些特定的格式。你忽略了一半的问题... – deceze

array_unique find first unique values from the array with id and that is the reason $cityarry is different from $skillarray. Please check image that will easy to understand...:)
