We may If the original array itself has been reordered, then after the array merging is completed, you must reorder the resulting new array. The following example introduces how to use the PHP function array_merge():

<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>
