$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爲$skillsarray，得到的結果作爲array_unique - PHP - 笨

[ 「PHP」，「Java」的，「IOS」如果我用array_unique

對於$cityarray，得到的結果作爲

{ 「0」：「奈」，「1」：「與Theni」，「3」：「木MBAI」，「7」：「海得拉巴」，「9」：「馬杜賴」}

任何人都可以解釋爲什麼array_unique($cityarray)是生產字典結果呢？

對於這兩種情況'array_unique'將返回唯一值的'array'。 –

'array_unique'將不會返回這些特定的格式。你忽略了一半的問題... – 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...:)
