php 替换 已有数组键值

<br />
	      foreach($arry1 as $key => $value) {<br />
 if (array_key_exists($key,$arry2))<br />
	{<br />
	  $arry2[$key]=$value;<br />
	}<br />
 else<br />
	{<br />
	  array_push($arry2,"$key=>$value");<br />
	  ksort($arry2);<br />
	}<br />
 	        }<br />


需求: 如果数组arry2中有arry1中的属性,则arry2中该属性值替换为arry1该属性值;如果没有则加入进入.
数组是 key=> value 那样的,如arry[a:1,b:[1,2]] 
上面代码为何有问题呢?

------解决方案--------------------
array_push($arry2,"$key=>$value");
改为
$arry2[$key] = $value");
