Printing an element of an Array?

If I define an array like this:

Code:

---

$arr = array(a => 'apple', b=> 'banana');

---

How can I access the first element of the array without knowing that the key is a?

echo $arr[?];

Would normally do $arr['a'], but let's say I don't know that the first element's key is a.

Thanks in advance.

If you want them back in a particular order then you'll need to use an array sorting function first. Then you can get the first element by:

PHP Code:

---

 reset($arr); // reset just incase array pointer is not at the beginning
 
 $firstval = current($arr); // get the first value
 $firstkey = key($array); // get the first key

Why would that ever be a predicament?

foreach($arr as $key => $value){
//Now I can find out the keys and values
break;//If I really only need the 1st element.
}

visualAd is also right.

If you need all the elements then use foreach, if not it will jsut waste resources.

Because I'm sorting the array after operations are done on the values, and I need to pull the first element. After the sorting, I don't know what the key is for the first element anymore.

Thanks, visualAd, that looks like it should work.

Wouldn't $arr[0] work, or am I missing something here?

Not if the array is not indexed.

Ohh, I thought they allways were. My Bad.
