匹配内爆数据与另一个内爆

问题描述：

I have data from two different tables where the data have been implode after being selected from Checkboxes and they are divided by a ','. After i selected them from the database the two varibles could look like this.

$firstvar = Red, Blue, Green, Yellow

$secondvar = Green, Purple, White

So i want to know how i can check, if there is a match, when there is at least one of the colors that match in the two variables.

i've been trying with:

if (strpos($firstvar , $firstvar ) !== false) {
    echo 'There is a match';
}

But it doesn't work.

我从两个不同的表中获取数据，其中数据在从Checkbox中选中后已经内爆，并且它们被一个 ''。从数据库中选择后，两个变量看起来像这样。 p>

  $ firstvar =红色，蓝色，绿色，黄色
 
 $ secondvar =绿色，紫色，  White 
  code>  pre> 
 
 所以我想知道如果匹配的话，我可以检查两个变量中是否至少有一种颜色匹配。   p> 
 
 
我一直在尝试： p> 
 
 
  if（strpos（$ firstvar，$ firstvar）！== false）{
  echo'有匹配'; 
} 
  code>  pre> 
 
 但它不起作用。 p> 
  div>

答

After fetching the result from the database, explode these two variables:

Just like this:

$firstvar = explode(",",$firstvar);
$secondvar = explode(",",$secondvar );

Now, use this function:

$match = array_intersect($firstvar,$secondvar);

and now, implode the resulted output:

$result = implode(",",$match);
echo $result;

Hope, this may be useful to you.
