PHP合并数组追加数组例子_PHP教程
array array_merge (array array1 array2…,arrayN)
下面是一个PHP合并数组的例子：
1
2$fruits = array("apple","banana","pear");
3$numbered = array("1","2","3");
4$cards = array_merge($fruits, $numbered);
5print_r($cards);
6// 输出结果：
7// Array ( [0] => apple [1] => banana [2] => pear [3] => 1 [4] => 2 [5] => 3 )
8?>
用PHP追加数组，使用array_merge_recursive()，将两个数组合并在一起，注意，与array_merge()函数是不一样的，array_merge()的两个数组有重复项时会覆盖掉，而array_merge_recursive()则不会。array_merge_recursive()语法：
array array_merge_recursive(array array1,array array2[…,array arrayN])
下面是一个PHP追加数组的例子：
view sourceprint?1
2$fruit1 = array("apple" => "red", "banana" => "yellow");
3$fruit2 = array("pear" => "yellow", "apple" => "green");
4$result = array_merge_recursive($fruit1, $fruit2);
5print_r($result);
6// 输出结果：
7// Array ( [apple] => Array ( [0] => red [1] => green ) [banana] => yellow [pear] => yellow )
8?>
现在apple 指向一个数组，由两个颜色值组成的索引数组。
