Simple method of merging two arrays in PHP

Array Merge Array_merge

Cases

The code is as follows	Copy Code
$array 1 = array (1=> ' 0 '); $array 2 = Array (1=> "data"); $result 3 = Array_merge ($array 2, $array 1),/* results are $array2 and $array1 values, the key name is reassigned * *

There is another way to use the "+" number directly

The code is as follows	Copy Code
A = Array ( ' A ', ); $b = Array ( ' U ', ); $c = $a + $b; Var_dump ($c); Output Array (1) { [0]=> String (1) "a" }

Intersection of arrays

This section only introduces some functions, as the usage is very simple, do not want to say more, so as not to complicate the simple things.

Append array

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

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 Array ([Apple] => Array ([0] => red [1] => green) [Banana] => yellow [pear] => yellow) ?>
