PHP implements two arrays to add the method, the PHP implementation of the array addition

The example in this article describes how PHP implements the addition of two arrays. Share to everyone for your reference. Specific as follows:

Example 1:

<?PHP$ARR1 = Array ("A" = "Chaoyang", "B" and "Haidian"); $arr 2 = Array ("h" = "Xicheng", "a" and "Dongcheng", "b" = "Fengtai"); $arr = $ arr1 + $arr 2;echo "
";p Rint_r ($arr);? >
The output results are as follows:
Array (  [A] = Chaoyang  [b] = Haidian  [h] = Xicheng)
Change the order of additions, Example 2:
<?PHP$ARR1 = Array ("A" = "Chaoyang", "B" and "Haidian"); $arr 2 = Array ("h" = "Xicheng", "a" = "Dongcheng", "B" = "Fengtai"); $arr = $arr 2 + $arr 1;echo "
";p Rint_r ($arr);? 
 
 The output is as follows: 
 
array ([h] = Xicheng [A] = Dongcheng [b] = Fengtai) 
 
 From the above two examples, you can see: 
 The 
 (1) addition is the following array, which is added to the previous array; 
 (2) The key name is not overwritten.
