本文实例讲述了PHP查找数值数组中不重复最大和最小的10个数的方法。分享给大家供大家参考。具体如下:
1. php代码如下:
1
2
3
4
5
6
7
8
9
10
11
12
13
|
//随机生成1万个元素的数组 for ( $i =0; $i <10000; $i ++){ $ary []=rand(1,100000); } $ary = array_unique ( $ary ); //去重复数值 sort( $ary ); //顺序排序 $min_10 = array_slice ( $ary ,0, 10); //取出最小的10个数值 $max_10 = array_slice ( $ary ,-10, 10); //取出最大的10个数值 rsort( $max_10 ); //倒序排序最大的10个数值 echo '<pre>' ; print_r( $min_10 ); print_r( $max_10 ); unset( $ary , $min_10 , $max_10 ); |
2. 运行结果如下:
1
2
3
4
5
6
7
8
9
10
11

Array ( [0] => 16 [1] => 19 [2] => 22 [3] => 31 [4] => 40 [5] => 49 [6] => 71 [7] => 74 [8] => 80 [9] => 92 ) Array ( [0] => 99997 [1] => 99991 [2] => 99973 [3] => 99958 [4] => 99955 [5] => 99946 [6] => 99939 [7] => 99933 [8] => 99927 [9] => 99900 ) |
希望本文所述对大家的php程序设计有所帮助。
