Sounds like a homework question.

Homeworky answer:

$array = array('log0'=>233,'log1' => 354,'log2' => 232,'log3' => 255);
$count=1;
foreach($array as $key=>$value){
if($count==1 ){
$low_val =$value;
$low_key=$key;
}
elseif($value<$low_val){
$low_val =$value;
$low_key=$key;
}
$count++;
}
echo "$low_key => $low_val";

How to handle null values and duplicates left as an exercise. :-)
