PHP循环遍历整个多维数组，但只返回一个结果

Question

I have got an multidimensional array on which I run a foreach loop.

I basically want to see if I've got the country_url stored in an database. If it is in the database then I'll echo "exists" but if it doesn't then I want to echo "doesn't exist". I don't want it to tell me for each array if it exists or not, but I want the foreach loop to tell me whether the country_url exists in one of the arrays or not.

foreach ($countriesForContinent as $country) {
    if ($country['country_url']==$country_url) {
        echo "exists";
    } else {
        echo "doesn't exist";
    }
}

Would anyone be able to help me out with this?

Try this:

$exist = false;    
foreach ($countriesForContinent as $country) {
        if ($country['country_url']==$country_url) {
            $exist = true;
            break;
        }
    }

if ($exist){
   echo "exists";
} else {
   echo "doesn't exist";
}
