本文实例讲述了php实现搜索一维数组元素并删除二维数组对应元素的方法。分享给大家供大家参考。具体如下:

定义一个一维数组一个二维数组如下

$fruit=array('apple','orange');
$products = array( array('name'=>'apple','price'=>23.4),
array('name'=>'orange','price'=>45.3),
array('name'=>'biscuit','number'=>5,'price'=>34)
);

Copy after login

需要实现从$products数组中查找元素是否和数组$fruit元素有交集,如果有的话保留,否则删除.

实现方法为:

foreach($products as $key=>$value)
{
   if(!in_array($value["name"],$fruit))
   unset($products[$key]);
}
array_values($products);
//使用unset()销毁数组元素时候应注意索引问题最好使用array_values()给数组重新排序

Copy after login

希望本文所述对大家的php程序设计有所帮助。
