PHP merges two-dimensional arrays into one two-dimensional array.

Question: There are the following two 2D arrays: 1 $ aArray (0 & gt; Array (id & gt; 66, class_name & gt; www.iiwnet.com), 1 & gt; array (id & gt; 67, class_name & gt; linux); 2 $ bArray (0 & gt; Array (class_count &

Question: There are the following two-dimensional arrays

1
$ A = Array (0 => Array (id => 66, class_name => www.iiwnet.com), 1 => Array (id => 67, class_name => linux ));
2
$ B = Array (0 => Array (class_count => 8), 1 => Array (class_count => 2 ));
The content of the two arrays is as follows:

1
Array (0 => Array (id => 66, class_name => www.iiwnet.com, class_count => 8), 1 => Array (id => 67, class_name => linux, class_count => 2 ));
Someone must have encountered this question. There are two solutions that can be provided if someone in the group asks me today.
The following code is provided by PHP Tutorial.
