从一个数组,PHP得到3个最低值 [英] Get 3 lowest values from an array, PHP
问题描述
所以我知道 MIN()
可以让我从一个数组中的最低值,但我需要一个数组的3最低值。
假设我的数组被命名为 $ myArray的
:
我用 ASORT($ myArray的)
我的数组,然后的print_r($ myArray的)
输出这样的:
阵列(
[137] => 4.90416668118
[135] => 7.1203544474
[18] => 7.2476262434
[81] => 8.37903400152
[33] => 9.1074567001
[4] => 9.90788482793
[138] => 10.2493339987
[5] => 11.6024401676
[63] ......等等,直到
[124] => 8727.73285117
[153] => 8727.73285117
[117] => 8727.73285117
)
我
如何获得第3的值或X值第一我需要...
我应该已经指定:是否有可能与丢失钥匙要做到这一点
ASORT($ yourarray,SORT_NUMERIC);
的print_r(array_slice($ yourarray,0,3,真实));
http://www.php.net/manual/en/function。 asort.php
http://www.php.net/manual/en/ function.array-slice.php
So I know that min()
can get me the lowest value from an array, however I need the 3 lowest values from an array.
assuming my array is named $myArray
:
I used asort($myArray)
on my array, then print_r($myArray)
outputs this:
Array (
[137] => 4.90416668118
[135] => 7.1203544474
[18] => 7.2476262434
[81] => 8.37903400152
[33] => 9.1074567001
[4] => 9.90788482793
[138] => 10.2493339987
[5] => 11.6024401676
[63]...and so on until
[124] => 8727.73285117
[153] => 8727.73285117
[117] => 8727.73285117
)
How can I get the 3 first values or the X first values should I need to...
I SHOULD HAVE SPECIFIED: Is it possible to do this with losing the keys?
asort($yourarray, SORT_NUMERIC);
print_r(array_slice($yourarray, 0, 3, true));
