i would like to add array to a matrix(multidimensional) array.
e.g.
$a = array ('a','b','1');
$b = array ('b','c','1');
$matrix += $a;
$matrix += $b;
//data in $matrix = array( array('a','b','1'), array('b','c','1') );

I think array_push is what you're after.
$a = array ('a','b','1');
$b = array ('b','c','1');
$matrix = array();
array_push($matrix, $a);
array_push($matrix, $b);
var_dump($matrix);
You can also simply add it with square brackets which will do the same thing:
$a = array ('a','b','1');
$b = array ('b','c','1');
$matrix = array();
$matrix[] = $a;
$matrix[] = $b;
var_dump($matrix);
Pushes $a in to $matrix, and then the 2nd line pushed $b, you are then presented with:
array (size=2)
0 =>
array (size=3)
0 => string 'a' (length=1)
1 => string 'b' (length=1)
2 => string '1' (length=1)
1 =>
array (size=3)
0 => string 'b' (length=1)
1 => string 'c' (length=1)
2 => string '1' (length=1)

Simply use :
$a = array ('a','b','1');
$b = array ('b','c','1');
$matrix = array();
$matrix[] = $a;
$matrix[] = $b;
This will give you :
Array
(
[0] => Array
(
[0] => a
[1] => b
[2] => 1
)
[1] => Array
(
[0] => b
[1] => c
[2] => 1
)
)

You can add 2 array in $matrix:
$a = array ('a','b','1');
$b = array ('b','c','1');
$matrix = array();
$matrix[] = $a;
$matrix[] = $b;

Use array_push
<?php
$a = array ('a','b','1');
$b = array ('b','c','1');
$matrix = [];
array_push($matrix, $a);
array_push($matrix, $b);
print_r($matrix);
Result:
Array
(
[0] => Array
(
[0] => a
[1] => b
[2] => 1
)
[1] => Array
(
[0] => b
[1] => c
[2] => 1
)
)

you can easily use array merge
$a = array ('a','b','1');
$b = array ('b','c','1');
$matrix = array_merge($a, $b);
print_r($matrix);
//Array ( [0] => a [1] => b [2] => 1 [3] => b [4] => c [5] => 1 )
