Just wanna share to you the code for a simple PHP calculator, hope it helps especially those who are learning PHP.

<?php
if(isset($_POST['calc']) && $_POST['calc'] == "Calculate")
{
    $_POST['int1']=trim((int)$_POST['int1']);
    $_POST['int2']=trim((int)$_POST['int2']);
    $_POST['math']=$_POST['math'];
   
    $int1=$_POST['int1'];
    $int2=$_POST['int2'];
    $math=$_POST['math'];
    if(!empty($math) && $math == 1)
    {
        $math="+";
        $tot=$int1+$int2;
    }
    elseif(!empty($math) && $math == 2)
    {
        $math="-";
        $tot=$int1-$int2;
    }
    elseif(!empty($math) && $math == 3)
    {
        $math="/";
        $tot=$int1/$int2;
    }
    elseif(!empty($math) && $math == 4)
    {
        $math="*";
        $tot=($int1*$int2);
    }
   
   
    print "$int1 $math $int2 = $tot";
    exit;
}
else
{
        //this is html embedded inside PHP
    print "<form action='".$_SERVER['PHP_SELF']."' method='post'>
    number 1:<input type='text' name='int1' /><br/>
