Pls I need a php code for addition of two numbers together. I am to add input tag to it and place holder. Pls help me. Thanks and God bless.

I only know Javascript ,but you can draw inspiration from this



<form>
<input type = "number" placeholder= "first number">


<input type = "number" id='f' placeholder= "second number">


<input type = "number" id='result' placeholder= "second number">


<input type = "button" id='result' type="submit">
</form>



<script>


function add(){


var firstNumber =
document.getElementById('f').value;



var secondNumber =
document.getElementById('s').value;



var add = first + second;



document.getElementById('result').
INNERHTML = "result is "+ add;



}

document.getElementById('result').addEventListener ('click', add, false);
</script>

i don't understand your question that much, but try this.

<!DOCTYPE html>
<html lang="en">
   <head>
      <title>Untitled</title>
   </head>
   <body>
      <form action='' method='post'>
          <input name='first_num' type='text' placeholder='First Number here' />
          <input name='second_num' type='text' placeholder='Second Number here' />
          <input type='submit' value='Add Number' />
      </form>
      <?php
      if($_SERVER['REQUEST_METHOD']=='POST'){
          $sum = $_POST['first_num'] + $_POST['second_num'];
          echo $sum;
      }
      ?>
   </body>
</html>
