PHP Program to find the even-odd number

<?php
$a=4;
if($a%2==0)
{
echo $a ." is Even number";
}
else
{
echo $a . " is odd number";
}
echo "<title>Even | Odd</title>";

?>

<?php

$a=4;

if($a%2==0)

{

echo $a ." is Even number";

}

else

{

echo $a . " is odd number";

}

echo "<title>Even | Odd</title>";

PHP Program to find the even-odd number with form

<html>
<body>
<form method="post" action="">
 <input type="text" name="num" placeholder="Enter Any Number">
 <input type="submit" name="sub" value="calculate">

</form>

</body>
</html>
 <?php
    if(isset($_POST['sub']))
	{
	  $NUM=$_POST['num'];
	  if($NUM%2==0)
	  {
	   echo "<h2>".$NUM. " is even number </h2>";
	  }
	  else 
	   {
	    echo "<h2>".$NUM. " is Odd number </h2>";
	   }
	}
 
 ?>

<html>

<body>

</form>

</body>

</html>

<?php

if(isset($_POST['sub']))

{

$NUM=$_POST['num'];

if($NUM%2==0)

{

echo "<h2>".$NUM. " is even number </h2>";

}

else

{

echo "<h2>".$NUM. " is Odd number </h2>";

}

PHP Program to find the even-odd number with a database

<html>
<body>
<form method="post" action="">
 <input type="text" name="num">
 <input type="submit" name="sub" value="calculate">

</form>

</body>
</html>
 <?php
  include 'connection.php';
    if(isset($_POST['sub']))
	{
	  $NUM=$_POST['num'];
	  if($NUM%2==0)
	  {
	    mysql_query("insert into even(number) values('$NUM')");
		$sel=mysql_query("select * from even");
		
		  echo $NUM . " is  even";
		
		
	  }
	  else 
	   {
	     mysql_query("insert into odd(number) values('$NUM')");
		 $sel=mysql_query("select * from Odd");
		  echo $NUM. "   is odd";
	   }
	}
 
 ?>

<html>

<body>

</form>

</body>

</html>

<?php

include 'connection.php';

if(isset($_POST['sub']))

{

$NUM=$_POST['num'];

if($NUM%2==0)

{

mysql_query("insert into even(number) values('$NUM')");

$sel=mysql_query("select * from even");

echo $NUM . " is even";

}

else

{

mysql_query("insert into odd(number) values('$NUM')");

$sel=mysql_query("select * from Odd");

echo $NUM. " is odd";

}

now creates the connection.php file to make a database connection.

connection.php

<?php
	$conn = mysql_connect('localhost', 'root', '');
	if (!$conn)
	{
		die('Could not connect: ' . mysql_error());
	}
	mysql_select_db("cal", $conn);
?>

<?php

$conn = mysql_connect('localhost', 'root', '');

if (!$conn)

{

die('Could not connect: ' . mysql_error());

}

mysql_select_db("cal", $conn);
