php implements the method of searching for one-dimensional array elements and deleting the corresponding elements of the two-dimensional array, dimension two-dimensional array

The example of this article tells the php implementation of searching for the one-dimensional array elements and deleting them Method for corresponding elements of a two-dimensional array. Share it with everyone for your reference. The details are as follows:

Define a one-dimensional array and a two-dimensional array as follows

$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)
);

You need to find out whether the elements in the $products array intersect with the $fruit elements in the array. If so, keep them, otherwise delete them.

The implementation method is:

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

I hope this article will be helpful to everyone’s PHP programming design.
