Code implementation of vertical merging & horizontal merging of two-dimensional arrays in PHP

This article brings the content is about PHP two-dimensional array of vertical merge & horizontal Merge code implementation, there is a certain reference value, the need for friends can refer to, I hope to help you.

This article is mainly to share with you the first way of merging: Using the Array_merge method given by the PHP array API to merge an array, we hope to help everyone.

Code:

$a = Array (Array ("1", "2"), Array ("3", "4"), $b = Array ("A", "B"), Array ("C", "D"));          $c = Array_merge ($a, $b);p Rint_r ($c);

Results:

This method of merging becomes a B array appended to the a array.

The second method of merging:

Merging arrays with a foreach loop

Code:

<?php$a = Array (Array ("1", "2"), Array ("3", "4"), $b = Array ("A", "B"), Array ("C", "D"));  foreach ($a as $key = + $vo) {$list [] = Array_merge ($vo, $b [$key]);} print_r ($list);

Results:

The method is then merged into a B array inserted into the a array.
