在两个数组值中的关联数组中查找最小值键是相同的[重复]

• Finding the minimum value's key in an associative array 5 answers

In PHP, say that you have an associative array like this:

$pets = array(
   "cats" => 1,
   "dogs" => 1,
   "fish" => 2
);

How would I find the key with the lowest value and first matching? Here, I'd be looking for cats. Both cats and dogs are 1 value. But i need the first matching cause.

I am using

array_keys($pets, min($pets));

But it gives me the second key(dogs) always. I need to get first key(cats) for lowest value.Is it possible?

Thanks in advance.

check this-

$pets = array(
    "cats" => 1,
    "dogs" => 1,
    "fish" => 2
);

echo array_search(min($pets), $pets);
