PHP 数组的添加和读取

Posted 2020-09-05 godlei

在实际的开发中，会经常使用数组的添加和读取。这里把经常使用的操作记下来，以备以后查阅。

 1 <?php
 2 //一维数值数组
 3 $list = array(‘wang‘,‘god‘);
 4 $list[] =‘biaobiao‘;
 5 $list[] = ‘chaofan‘;
 6 foreach($list as $v){
 7     echo $v."<br />";
 8 }
 9 
10 //一维关联数组
11 $list1 = array(
12     ‘name‘ => ‘god‘,
13     ‘info‘ => ‘XXXXX‘,
14     ‘number‘ => 123213
15     );
16 $list1[‘address‘] = ‘Beijing‘;
17 foreach($list1 as $key => $value){
18     echo $key . "=>" . $value."<br />";
19 }
20 
21 
22 //二位数值数组
23 $list = array(
24     array(1,4,12,3),
25     array(2,5,6,10),
26     array(3,7,9,8)
27 );
28 foreach($list as $value){
29     foreach($value as $v){
30         echo $v ." ";
31     }
32     echo "<br />";
33 }
34 
35 //二维数组关联数组
36 $lists = array();
37 $list0 = array(
38     ‘name‘ => ‘god‘,
39     ‘info‘ => ‘XXXXX‘,
40     ‘number‘ => 123213
41 );
42 $lists[] = $list0;
43 $list1 = array(
44     ‘name‘ => ‘chaofan‘,
45     ‘info‘ => ‘SSSSSS‘,
46     ‘number‘ => 41123
47 );
48 $lists[] = $list1;
49 $list2 = array(
50     ‘name‘ => ‘biaobiao‘,
51     ‘info‘ => ‘#######‘,
52     ‘number‘ => 56732
53 );
54 $lists[] = $list2;
55 
56 foreach($lists as $key => $value){
57     echo "name:".$lists[$key][‘name‘]." info:".$lists[$key][‘info‘]." number:".$lists[$key][‘number‘]."<br />";
58 }
59 
60 foreach($lists as $key => $value){
61     $lists[$key][‘nick‘] =  $lists[$key][‘name‘]." host";
62 }
63 ?>
