php

<code>array(3) {
  [0] =&gt; array(9) {
    [0] =&gt; string(1) "1"
    [1] =&gt; string(3) "175"
    [2] =&gt; string(1) "2"
    [3] =&gt; string(2) "22"
    [4] =&gt; string(2) "22"
    [5] =&gt; string(2) "-1"
    [6] =&gt; string(1) "0"
    [7] =&gt; string(11) "小份+0元"
    [8] =&gt; int(44)
  }
  [1] =&gt; array(9) {
    [0] =&gt; string(1) "1"
    [1] =&gt; string(3) "175"
    [2] =&gt; string(1) "3"
    [3] =&gt; string(2) "22"
    [4] =&gt; string(2) "22"
    [5] =&gt; string(2) "-1"
    [6] =&gt; string(1) "0"
    [7] =&gt; string(11) "小份+0元"

请问如何把一样的一维数组合并
并且如果两者一样把 [2] => string(1) "2"的值相加后的值作为新的值.键不变
