Two ways to merge two two-dimensional arrays into one two-dimensional array in PHP_PHP Tutorial

Title: There are the following 2 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 contents of the two arrays are as above. How to merge $a and $b into a new two-dimensional array? The content of the new array is required to be 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 problem. Someone asked it in the group today and I gave two solutions
