PHP merges two-dimensional arrays into one two-dimensional array. 2 solutions _ PHP Tutorial

PHP combines two-dimensional arrays and one two-dimensional array. Question: There are the following two 2D arrays: 1 $ aArray (0 Array (id66, class_namewww.iiwnet.com), 1 Array (id67, class_namelinux), 2 $ bArray (0 Array (class_count8 ), 1 Array question: there are the following two 2D arrays

1
$ A = Array (0 => Array (id => 66, class_name => www.iiwnet.com), 1 => Array (id => 67, class_name => linux ));
2
$ B = Array (0 => Array (class_count => 8), 1 => Array (class_count => 2 ));
The content of the two arrays is as follows:

1
Array (0 => Array (id => 66, class_name => www.iiwnet.com, class_count => 8), 1 => Array (id => 67, class_name => linux, class_count => 2 ));
Someone must have encountered this question. There are two solutions that can be provided if someone in the group asks me today.
The following code is provided by PHP Tutorial.

Method 1:
02

03
Function arrpreg (){
04
$ A = Array (0 => Array (id => 66, class_name => www.iiwnet.com), 1 => Array (id => 67, class_name => linux ));
05
$ B = Array (0 => Array (class_count => 8), 1 => Array (class_count => 2 ));
06
$ Arr = array ();
07
Foreach ($ a as $ k => $ r ){
08
Foreach ($ r as $ k1 => $ r1 ){
09
$ Arr [$ k] [$ k1] = $ r1;
10
}
11
}
12
Foreach ($ B as $ k => $ r ){
13
Foreach ($ r as $ k1 => $ r1 ){
14
$ Arr [$ k] [$ k1] = $ r1;
15
}
16
}
17
Return $ arr;
18
}
19
$ Ar = arrpreg ();
20
Echo'

';
21
     print_r($ar);
22
    echo '

';
23
?>
24

25
Method 2:
26

27
$ A = array (0 => Array (id => 66, class_name => www.iiwnet.com), 1 => Array (id => 67, class_name => linux ));
28
$ B = array (0 => Array (class_count => 8), 1 => Array (class_count => 2 ));
29
$ Arr = array ();
30
Foreach ($ a as $ k => $ r ){
31
$ Arr [] = array_merge ($ r, $ B [$ k]);
32
}
33
Echo'

';
34
    print_r($arr);
35
    echo '

';

Rows 1 $ a = Array (0 = Array (id = 66, class_name = www.iiwnet.com), 1 = Array (id = 67, class_name = linux )); 2 $ B = Array (0 = Array (class_count = 8), 1 = Array...
