二维数组追加二位数组

Question

数组A:
array(2) {
[0] => array(3) {

["sum"] => string(1) "9"
["group_id"] => string(1) "2"
["group_name"] => string(9) "第一组"

}
[1] => array(3) {

["sum"] => string(1) "3"
["group_id"] => string(1) "3"
["group_name"] => string(9) "第二组"

}
}

数组B:
array(2) {
[0] => array(2) {

["sum"] => string(1) "9"
["user_name"] => string(1) "小明"

}
[1] => array(2) {

["sum"] => string(1) "3"
["user_name"] => string(1) "小红"

}
}

如何将数组B追加到数组A 变成:
array(4) {
[0] => array(3) {

["sum"] => string(1) "9"
["group_id"] => string(1) "2"
["group_name"] => string(9) "第一组"

}
[1] => array(3) {

["sum"] => string(1) "3"
["group_id"] => string(1) "3"
["group_name"] => string(9) "第二组"

}
[3] => array(2) {

["sum"] => string(1) "9"
["user_name"] => string(1) "小明"

}
[4] => array(2) {

 ["sum"] => string(1) "3"
  ["user_name"] => string(1) "小红"

}
}
