Example of an array merge append array in PHP

PHP Merge Array We can use the Array_merge () function, and the Array_merge () function returns a federated array. The resulting array begins with the first input array parameter, appended in the order in which the following array parameters appear. In the form of:

Array Array_merge (array array1 array2...,arrayn)

The following is an example of a php merge array:

The code is as follows	Copy Code
<?php $fruits = Array ("Apple", "banana", "pear"); $numbered = Array ("1", "2", "3"); $cards = Array_merge ($fruits, $numbered); Print_r ($cards); Output results: Array ([0] => Apple [1] => banana [2] => pear [3] => 1 [4] => 2 [5] => 3) ?>

Append the array with PHP, use array_merge_recursive (), combine two numbers together, note that the Array_merge () function is not the same, Array_merge () of the two array with duplicates will be overwritten, and Array_ Merge_recursive () is not. Array_merge_recursive () Syntax:

Array array_merge_recursive (array Array1,array array2[...,array Arrayn])

The following is an example of a PHP append array:

The code is as follows	Copy Code
<?php $fruit 1 = Array ("Apple" => "red", "banana" => "yellow"); $fruit 2 = Array ("pear" => "yellow", "apple" => "green"); $result = array_merge_recursive ($fruit 1, $fruit 2); Print_r ($result); Output results: Array ([Apple] => Array ([0] => red [1] => green) [Banana] => yellow [pear] => yellow) ?>

Now Apple points to an array of indexed arrays of two color values, and there's a strange way to merge arrays

The Array_splice () syntax format is:
Array array_splice (array array, int Offset[,length[,array replacement]])

Example

The code is as follows	Copy Code
<?php $fruits = Array ("Apple", "Banana", "Orange", "Pear", "Grape", "Lemon", "watermelon"); $subset = Array_splice ($fruits, 4); Print_r ($fruits); Print_r ($subset); The output results are: Array ([0] => Apple [1] => Banana [2] => Orange [3] => Pear) Array ([0] => Grape [1] => Lemon [2] => watermelon) ?>

We can also use optional parameter replacement to specify an array to replace the target part. Take a look at the following example:

code is as follows	copy code
<?php $fruits = Array ("Apple", "Banana", "Orange", "Pear", "Grape", "Lemon", "watermelon"); $subset = Array_splice ($fruits, 2,-1, Array ("Green Apple", "Red Apple")); Print_r ($fruits); Print_r ($subset); //output: //Array ([0] => Apple [1] => Banana [2] => Green Apple [3] => Red Apple [4] => Watermel ON) //Array ([0] => Orange [1] => Pear [2] => Grape [3] => Lemon)
