PHP Array Exercises : Calculate and display average temperature

PHP Array: Exercise-9 with Solution

Write a PHP script to calculate and display average temperature, five lowest and highest temperatures.

Recorded temperatures : 78, 60, 62, 68, 71, 68, 73, 85, 66, 64, 76, 63, 75, 76, 73, 68, 62, 73, 72, 65, 74, 62, 62, 65, 64, 68, 73, 75, 79, 73

Sample Solution:

PHP Code:

<?php
$month_temp = "78, 60, 62, 68, 71, 68, 73, 85, 66, 64, 76, 63, 81, 76, 73,
68, 72, 73, 75, 65, 74, 63, 67, 65, 64, 68, 73, 75, 79, 73";
$temp_array = explode(',', $month_temp);
$tot_temp = 0;
$temp_array_length = count($temp_array);
foreach($temp_array as $temp)
{
 $tot_temp += $temp;
}
 $avg_high_temp = $tot_temp/$temp_array_length;
 echo "Average Temperature is : ".$avg_high_temp."
"; 
sort($temp_array);
echo "
 List of five lowest temperatures :";
for ($i=0; $i< 5; $i++)
{ 
echo $temp_array[$i].", ";
}
echo "
List of five highest temperatures :";
for ($i=($temp_array_length-5); $i< ($temp_array_length); $i++)
{
echo $temp_array[$i].", ";
}
?>

Sample Output:

Average Temperature is : 70.6                               
List of five lowest temperatures : 60,  62,  63,  63,  64,
List of five highest temperatures : 76, 78,  79,  81,  85,
