Answer 1

您正在寻找array_intersect.

array_intersect() 返回一个数组，其中包含所有参数中存在的 array1 的所有值。请注意，密钥是保留的。

array_intersect($explode_term, $explode_tags);

Answer 2

$search_terms="house,car,boy,table";
$cats="1,2,3,4,car,boy,fly,girl";

$explode_term=explode(",",$search_terms);
$explode_tags=explode(",",$cats);   

$compare=array_diff_assoc($explode_term, $explode_tags);

foreach ($compare as $compa)
{
    print $compa;
    print "<br>";   
}
