php：输出关联数组特定范围的数据
一、php源码（将“关联数组”转化为“索引数组”，然后输出）
1 <?php
2
3 // define data structure
4 class SCOPE
5 {
6 private $scp_start="";
7 private $scp_end="";
8
9 public function set_start($scp_start)
10 {
11 $this->scp_start=$scp_start;
12 }
13
14 public function get_start()
15 {
16 return $this->scp_start;
17 }
18
19 public function set_end($scp_end)
20 {
21 $this->scp_end=$scp_end;
22 }
23
24 public function get_end()
25 {
26 return $this->scp_end;
27 }
28 }
29
30
31 // print array, $array_var = index array
32 function print_array($scope_var, $array_var)
33 {
34 for($st=$scope_var->get_start(); $st!=$scope_var->get_end(); $st++)
35 {
36 echo "array[$st]_out = " . $array_var[$st] . PHP_EOL;
37 }
38 }
39
40
41
42 // define relation array
43 $array_laohu=array("bg"=>"book1", 2=>"book2", 3=>"book3", 4=>"book4", "ed"=>"book5");
44
45 // translate array; relation_array -> index_array
46 $array_translate = array_values($array_laohu);
47
48 // define scope variable and set its values.
49 $sc = new SCOPE;
50 $sc->set_start(0);
51 $sc->set_end(6);
52
53 // print array in the scope
54 print_array($sc, $array_translate);
55
56
57
58 ?>
二、运行结果
