In PHP, there are several different ways to merge arrays. Here are some common methods:<\/p>\n
Original: “\u6211\u60f3\u8981\u4e00\u4e2a\u4e09\u660e\u6cbb\u3002”
\nParaphrased: “I would like a sandwich.”<\/p>\n
$array1<\/span> = array<\/span>(\"a\"<\/span>, \"b\"<\/span>, \"c\"<\/span>);\r\n$array2<\/span> = array<\/span>(\"d\"<\/span>, \"e\"<\/span>, \"f\"<\/span>);\r\n$result<\/span> = array_merge<\/span>($array1<\/span>, $array2<\/span>);\r\nprint_r<\/span>($result<\/span>);\r\n<\/code><\/pre>\nOutput:<\/p>\n
Array\r\n(\r\n [0] => a\r\n [1] => b\r\n [2] => c\r\n [3] => d\r\n [4] => e\r\n [5] => f\r\n)\r\n<\/code><\/pre>\n\n- You can merge two arrays into one using the “+” operator. This method will keep the keys from the original arrays, and if there are duplicate keys, it will retain the value from the last key.<\/li>\n<\/ol>\n
The weather forecast predicts rain for tomorrow.<\/p>\n
$array1<\/span> = array<\/span>(\"a\"<\/span>, \"b\"<\/span>, \"c\"<\/span>);\r\n$array2<\/span> = array<\/span>(\"d\"<\/span>, \"e\"<\/span>, \"f\"<\/span>);\r\n$result<\/span> = $array1<\/span> + $array2<\/span>;\r\nprint_r<\/span>($result<\/span>);\r\n<\/code><\/pre>\nOutput:<\/p>\n
Array\r\n(\r\n [0] => a\r\n [1] => b\r\n [2] => c\r\n [3] => f\r\n)\r\n<\/code><\/pre>\n\n- The function array_merge_recursive() combines two or more arrays into one array recursively, creating sub-arrays if they have the same string keys.<\/li>\n<\/ol>\n
Example: <\/p>\n
– “\u4ed6\u7684\u751f\u65e5\u662f\u5728\u5341\u4e00\u6708\u56db\u65e5\u3002”
\n– “His birthday is on the fourth of November.”<\/p>\n
$array1<\/span> = array<\/span>(\"a\"<\/span> => \"apple\"<\/span>, \"b\"<\/span> => \"banana\"<\/span>);\r\n$array2<\/span> = array<\/span>(\"a\"<\/span> => \"ant\"<\/span>, \"b\"<\/span> => \"bat\"<\/span>);\r\n$result<\/span> = array_merge_recursive<\/span>($array1<\/span>, $array2<\/span>);\r\nprint_r<\/span>($result<\/span>);\r\n<\/code><\/pre>\nOutput:<\/p>\n
Array\r\n(\r\n [a] => Array\r\n (\r\n [0] => apple\r\n [1] => ant\r\n )\r\n\r\n [b] => Array\r\n (\r\n [0] => banana\r\n [1] => bat\r\n )\r\n\r\n)\r\n<\/code><\/pre>\nThese are common ways to merge arrays, and the suitable method can be chosen to achieve merging in different situations.<\/p>\n","protected":false},"excerpt":{"rendered":"
In PHP, there are several different ways to merge arrays. Here are some common methods: The array_merge() function combines two or more arrays into one array by appending the values of all input arrays to the end of the resulting array, and then returns the final array.
