This is a PHP script to calculate and display average temperature, five lowest and highest temperatures. <?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].", "; } ?>

Let's create a simple calculator <?php  if(isset($_POST['sub']))  {   $txt1=$_POST['n1'];                       $txt2=$_POST['n2'];     $oprnd=$_POST['sub'];  if($oprnd=="+")  $res=$txt1+$txt2; else if($oprnd=="-")              $res=$txt1-$txt2; else if($oprnd=="x")        $res=$txt1*$txt2; else if($oprnd=="/")    $res=$txt1/$txt2;  } ?> <form method="post" action=""> Calculator <br> No1:<input name="n1" value="<?php echo $txt1; ?>"> <br> No2:<input name="n2" value="<?php echo $txt2; ?>"> <br> Res:<input name="res" value="<?php echo $res; ?>"> <br> <input type="submit" name="sub" value="+"> <input type="submit" name="sub" value="-"> <input type="submi...
