通过for循环查找数组中的最大值和最小值

Question

I want to find the maximum and minimum value by the for loop, but problem is that when array value is start from a maximum number like (100,30,50,60) then output is the correct first maximum value then, minimum value.

Otherwise output first minimum value, then maximum value.

any idea?

    //Number serial.
    $number = array(10,15,20,100,25,30);

    for ($i=0; $i<count($number); $i++){
        //Find maximum number by max function.
        if ($number[$i] == max($number)){
            //Print maximum number.
            echo " The max number is $number[$i] <br>" ;
        }
        //Find minimum number by min function.
        elseif ($number[$i] == min($number)) {
            //Print minimum  number.
            echo " The min number is $number[$i] <br>";
        }
    }
//Output: 
//The min number is 10
//The max number is 100 

When array value is start from a maximum number.

 //Number serial.
    $number = array(100,10,15,20,25,30);

    for ($i=0; $i<count($number); $i++){
        //Find maximum number by max function.
        if ($number[$i] == max($number)){
            //Print maximum number.
            echo " The max number is $number[$i] <br>" ;
        }
        //Find minimum number by min function.
        elseif ($number[$i] == min($number)) {
            //Print minimum  number.
            echo " The min number is $number[$i] <br>";
        }
    }
//Output:
//The max number is 100
//The min number is 10

Actually I think you dont need the for loop to begin with.... You can do something simple like this:

$number = array(15,20,100,10,25,30);
$max = max($number);
$min = min($number);
echo "min value is $min <br/>";
echo "max value is $max <br/>";

Update:

But if you want to flexibly, echo the statements according to the index of the min and max values then you can do something like this:

$number = array(15,20,100,10,25,30);
$max = max($number);
$min = min($number);
$max_idx = array_search($max,$number);
$min_idx = array_search($min,$number);
if($max_idx < $min_idx){
  echo "max value is $max 
";
  echo "min value is $min 
";
}else{
  echo "min value is $min 
";
  echo "max value is $max 
";
}

What this will do is, it will get the indices of the min and max values and depending on which is encountered first, it will print that statement first.

Hope it helps
