Find sum of randomly generated array

Right now I'm working on a PHP project where the user enters the lower limit and upper limit and the program will generate 5 numbers between that limit, print it out the randomly generated 5 numbers, and find and print the sum.

For some reason my program isn't getting passed the input (lower and upper limits).

<!DOCTYPE html>

<html lang = "en">

   <head>

      <title>Sum of the Digits!</title>

   </head>

   <body>

      <h1>Find the sum of five digits!</h1>

      <p>Enter in the lower and upper limits of the numbers you would like to 

         generate. Press "Calculate" to calculate the sum of the genreated numbers!

      </p>

      <form method="post" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>">

         Enter the lower limit: <input type = "number" name = "lowLim">

         Enter the upper limit: <input type = "number" name = "upLim">

         <input type = "submit">

      </form>

      <?php

         if($SERVER["REQUEST_METHOD"] == "POST"){



         $lowerLim = test_input($_POST["lowLim"]);

         $upperLim = test_input($_POST["upLim"]);

         $randomArray = array();

         $sumArray = array();

         $total = 0;

         $arrCounter = 0;

         var_dump ($lowerLim);







         for($i = 0; $i < 5; $i++){

         $randomRange = rand("$lowerLim","$upperLim");

         $randomArray = array($randomRange[i]);

         }



         $sumArray = array($randomArray);

         $total = array_sum($sumArray);

         }

         function test_input($data){

         $data = trim($data);

         $data = stripslashes($data);

         $data = htmlspecialchars($data);

         return $data;

         }









         echo "First number generated: ".$randomArray[0];

         echo "Second number generated: ".$randomArray[1];

         echo "Third number generated: ".$randomArray[2];

         echo "Fourth number generated: ".$randomArray[3];

         echo "Fifth number generated: ".$randomArray[4];







         echo "The sum of the generated digits is:".$total;





         ?>

You had a couple of issues in your code:

typo: $_SERVER, not $SERVER

The result output need to be inside the if ... == POST brackets, or they will be called with the input

In your loop of assigning the random values, you kept overwriting the $randomArray

array_sum() needs to be called on the $randomArray directly, not on an
array of the random array.

Here is a corrected version of your code:

<!DOCTYPE html>

<html lang = "en">

   <head>

      <title>Sum of the Digits!</title>

   </head>

   <body>

      <h1>Find the sum of five digits!</h1>

      <p>Enter in the lower and upper limits of the numbers you would like to 

         generate. Press "Calculate" to calculate the sum of the genreated numbers!

      </p>

      <form method="post" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>">

         Enter the lower limit: <input type = "number" name = "lowLim">

         Enter the upper limit: <input type = "number" name = "upLim">

         <input type = "submit">

      </form>

      <?php

         if($_SERVER["REQUEST_METHOD"] == "POST")

         {



             $lowerLim = test_input($_POST["lowLim"]);

             $upperLim = test_input($_POST["upLim"]);

             $randomArray = array();

             $sumArray = array();

             $total = 0;

             $arrCounter = 0;

             var_dump ($lowerLim);







             for($i = 0; $i < 5; $i++)

             {

                 $randomRange = rand("$lowerLim","$upperLim");

                 $randomArray = $randomRange;

             }



             $total = array_sum($randomArray);



              echo "First number generated: " . $randomArray[0];

             echo "Second number generated: " . $randomArray[1];

             echo "Third number generated: " . $randomArray[2];

             echo "Fourth number generated: " . $randomArray[3];

             echo "Fifth number generated: " . $randomArray[4];

               echo "The sum of the generated digits is:".$total;

         }



         function test_input($data)

         {

             $data = trim($data);

             $data = stripslashes($data);

             $data = htmlspecialchars($data);

             return $data;

         }



         ?>

You had a couple of issues in your code:

typo: $_SERVER, not $SERVER

The result output need to be inside the if ... == POST brackets, or they will be called with the input

In your loop of assigning the random values, you kept overwriting the $randomArray

array_sum() needs to be called on the $randomArray directly, not on an
array of the random array.

Here is a corrected version of your code:

<!DOCTYPE html>

<html lang = "en">

   <head>

      <title>Sum of the Digits!</title>

   </head>

   <body>

      <h1>Find the sum of five digits!</h1>

      <p>Enter in the lower and upper limits of the numbers you would like to 

         generate. Press "Calculate" to calculate the sum of the genreated numbers!

      </p>

      <form method="post" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>">

         Enter the lower limit: <input type = "number" name = "lowLim">

         Enter the upper limit: <input type = "number" name = "upLim">

         <input type = "submit">

      </form>

      <?php

         if($_SERVER["REQUEST_METHOD"] == "POST")

         {



             $lowerLim = test_input($_POST["lowLim"]);

             $upperLim = test_input($_POST["upLim"]);

             $randomArray = array();

             $sumArray = array();

             $total = 0;

             $arrCounter = 0;

             var_dump ($lowerLim);







             for($i = 0; $i < 5; $i++)

             {

                 $randomRange = rand("$lowerLim","$upperLim");

                 $randomArray = $randomRange;

             }



             $total = array_sum($randomArray);



              echo "First number generated: " . $randomArray[0];

             echo "Second number generated: " . $randomArray[1];

             echo "Third number generated: " . $randomArray[2];

             echo "Fourth number generated: " . $randomArray[3];

             echo "Fifth number generated: " . $randomArray[4];

               echo "The sum of the generated digits is:".$total;

         }



         function test_input($data)

         {

             $data = trim($data);

             $data = stripslashes($data);

             $data = htmlspecialchars($data);

             return $data;

         }



         ?>

   </body>

</html>
