how to get lowest value

[jayipee]

hi to all. can anybody help me figuring out how to get the minimum
value from this list.

log1 354
log2 232
log3 155

from the above list i want to have a return value "log3" since this is
the lowest value in the list.

I tried to use $test = min(array('log1' =354,'log2' =232,'log3' =>
155));
but it returns only the value 155 and not log3

i would be very glad if someone can help me.

$array = array('log1' =354,'log2' =232,'log3' =155);
asort($array);
$min_key = reset(array_keys($array));

$array = array('log1' =354,'log2' =232,'log3' =155);
asort($array);
$min_key = reset(array_keys($array));

or:

$log_array = array("log1"=>354, "log3"=>155, "log2"=>232);
arsort($log_array);
$log_array = array_flip($log_array);
echo array_pop($log_array);

In most cases, yes.
Now try:
$log_array = array("log1"=>354, "log3"=>null, "log2"=>232);

You can see why I'm a bit reluctant to use values as the keys.

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. :-)

$array = array('log1' =354,'log2' =232,'log3' =155);
$test1 = array_search(min($array), $array);
$test2 = array_keys($array, min($array));

The difference between aray_search and array_keys is that _keys returns an
array of keys for matching elements. That means if several minimum values
are found, all matching elements are returned. Array_search just returns the
first.
