題目：有以下2個二維數組
1
$a=Array(0 => Array(id => 66,class_name => www.iiwnet.com),1 => Array(id => 67,class_name => linux ));
2
$b=Array(0 => Array(class_count=> 8),1 => Array(class_count => 2));
兩個數組內容如上，如何把$a和$b合並成為一個新的二維數組，要求新數組內容如下：
1
Array(0 => Array(id => 66,class_name => www.iiwnet.com，class_count=> 8),1 => Array(id => 67,class_name => linux ，class_count => 2));
這個題目一定有人遇到過 正好今天群裡有人問 就給出2種解法
以下代碼由 PHP教程網 原創提供
01
方法一：
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
$ar= arrpreg();
20
echo '<pre>';
21
print_r($ar);
22
echo '</pre>';
23
?>
24
25
方法二：
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 '<pre>';
34
print_r($arr);
35
echo '</pre>';
