【问题描述】：
$skillsarray = ["php","java","ios","php","php","php","php","java","java","ios"];
$cityarray = ["Chennai","Theni","Theni","Mumbai","Chennai","Theni","Chennai","Hyderabad","Theni","Madurai"];
如果我将array_unique 用于$skillsarray，得到的结果为
["php","java","ios"]
如果我将array_unique 用于$cityarray，得到的结果为
{"0":"Chennai","1":"Theni","3":"Mumbai","7":"Hyderabad","9":"Madurai"}
谁能解释为什么array_unique($cityarray) 会产生字典结果？
【问题讨论】：
-
对于这两种情况，
array_unique将返回具有唯一值的array。 -
array_unique不会返回这些特定格式。你忽略了一半的问题……
