Question

这是我的阵列：

$database[0] = array("country"=>"UK", "product" => "pen423", "company" => "ht789"); 
$database[1] = array("country"=>"USA", "product" => "pen123", "company" => "hi789"); 
$database[2] = array("country"=>"UK", "product" => "pen423", "company" => "ht789");
 $database[3] = array("country"=>"UK", "product" => "pen423", "company" => "ht789");
 $database[4] = array("country"=>"UK", "product" => "pen4023", "company" => "hi7789");

我想要获得的输出数组：＆＃34; Country＆＃34; =＆＃34;英国＆＃34;和＆＃34;公司＆＃34;喜欢＆＃34; ht％＆＃34;

因此，输出将是：

$database[0] = array("country"=>"UK", "product" => "pen423", "company" => "ht789"); 
$database[2] = array("country"=>"UK", "product" => "pen423", "company" => "ht789");
 $database[3] = array("country"=>"UK", "product" => "pen423", "company" => "ht789");

是否有可能像sql语句和没有使用循环？

Answer 1

您可以使用array_filter()。它接受一个回调，您可以在其中添加自定义逻辑到过滤结果集。

使用strpos()或substr()之类的字符串函数应该非常简单。

Answer 2

使用array_filter

function filterfunction($value) 
{

    if(strcmp($value['country'],"UK")!=0
      return false;
    if(strcmp(substr($value['company'],0,2),"ht")==0)
      return true;
    return false; 
}

$filterarr = array_filter($database, "filterfunction");

多维数组过滤器类似于mysql LIKE
