[英]array_unique not giving the correct output
this give results like 这给像这样的结果
Array( [0] => 5000 [1] => 5001 [2] => 3000 [3] => 3001 [4] => 5000 )
数组([0] => 5000 [1] => 5001 [2] => 3000 [3] => 3001 [4] => 5000)
When I use array_unique same result is obtained 当我使用array_unique时,获得相同的结果
Array ( [0] => 5000 [1] => 5001 [2] => 3000 [3] => 3001 [4] => 5000 )
数组([0] => 5000 [1] => 5001 [2] => 3000 [3] => 3001 [4] => 5000)
foreach($detail as $key => $value){
array_push($zips, $value);
}
}
array_unique($zips);
array_unique()
does not work by reference. array_unique()
不能通过引用工作。 That means, it won't actually modify the original array, just return a new array with the respective modifications. 这意味着,它实际上不会修改原始数组,而只是返回具有相应修改的新数组。 You need to save its output to a new (or the same) variable:
您需要将其输出保存到新的(或相同的)变量中:
foreach($detail as $key => $value){
array_push($zips, $value);
}
$zips = array_unique($zips);

不需要foreach
和array_push
,只需将其应用并保存到所需的变量$zips
:
$zips = array_unique(array_values($zips));
