Introduction
PHP is a server scripting language, and It is a powerful tool for making interactive and dynamic Web-pages. I have used WampServer 2.2 for following excercise..
<?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 " <br>List of five lowest temperatures :"; for ($i=0; $i< 5; $i++) { echo $temp_array[$i].", "; } echo "<br>List of five highest temperatures :"; for ($i=($temp_array_length-5); $i< ($temp_array_length); $i++) { echo $temp_array[$i].", "; } ?>
