给定这个数组:$inventory=array(array("type"=>"fruit","price"=>3.50),array("type"=>"milk","price"=>2.90),array("type"=>"pork","price"=>5.43),);我想按价格对$inventory的元素进行排序得到:$inventory=array(array("type"=>"pork","price"=>5.43),array("type"=>"fruit","price"=>3.50),array("type"=>"milk","price"=>2.90),);我该怎么做？

我使用AJAX获得了以下对象并将它们存储在一个数组中:varhomes=[{"h_id":"3","city":"Dallas","state":"TX","zip":"75201","price":"162500"},{"h_id":"4","city":"BeveryHills","state":"CA","zip":"90210","price":"319250"},{"h_id":"5","city":"NewYork","state":"NY","zip":"00010","price":"962500"}];我如何创建一个函数以按升序或降序顺序按price属性对对象进行排序
