arraymergephp具体函数合并对我们数组方法的解析

我们也许对如果原有数组本身已经被重新排序过，那么在数组合并完成以后，你必须针对产生出来的新数组重新再排序一次。下面这个范例就介绍PHP函数array_merge()的使用方式：

<ol class="dp-xml">
<li class="alt"><span><span>＜? /* 首先建立第一个数组 */   </span></span></li>
<li class=""><span> </span></li>
<li class="alt">
<span>$</span><span class="attribute"><font color="#ff0000">fruitArray</font></span><span> = </span><span class="attribute-value"><font color="#0000ff">array</font></span><span>("apple", "orange", "banana", "Peach", "pear");    </span>
</li>
<li class=""><span> </span></li>
<li class="alt"><span>/* 接下来建立第二个数组 */   </span></li>
<li class=""><span> </span></li>
<li class="alt">
<span>$</span><span class="attribute"><font color="#ff0000">vegArray</font></span><span> = </span><span class="attribute-value"><font color="#0000ff">array</font></span><span>("carrot", "green beans", "asparagus", "artichoke", "corn");    </span>
</li>
<li class=""><span> </span></li>
<li class="alt"><span>/* 现在使用array_merge()函数将两个数组合并成一个新的数组 */   </span></li>
<li class=""><span> </span></li>
<li class="alt">
<span>$</span><span class="attribute"><font color="#ff0000">goodfoodArray</font></span><span> = </span><span class="attribute-value"><font color="#0000ff">array_merge</font></span><span>($fruitArray, $vegArray);    </span>
</li>
<li class=""><span> </span></li>
<li class="alt"><span>/* 最后我们把合并后的新数组的所有元素的键（key）与值（value）都显示在网页上 */   </span></li>
<li class=""><span> </span></li>
<li class="alt"><span>while (list($key,$value) = each($goodfoodArray)) {   </span></li>
<li class=""><span> </span></li>
<li class="alt"><span>echo "$key : $value＜br＞";   </span></li>
<li class=""><span> </span></li>
<li class="alt"><span>}    </span></li>
<li class=""><span> </span></li>
<li class="alt"><span>?＞     </span></li>
</ol>

显示结果如下：

0 : apple

1 : orange

2 : banana

3 : Peach

4 : pear

5 : carrot

6 : green beans

7 : asparagus

8 : artichoke

9 : corn

PHP函数array_merge()在数组合并中的使用方法如上所示。
