<form action="Ex4-04-test.php" method="get">

Pick a number between 0 - 50:<br />

<input name="num_wanted" type="text" id="num_wanted" />

<input name="go" type="submit" value="Search for my Number!" />

</form>

CODE FOR SEARCHING ARRAY

 

<?php

$numWanted = $_POST['num_wanted'];

// create an array of numbers called $numArray

$numArray = array(12, 0, 89, 64, 23, 50);

?>

<?php

// use the array_search function to check if the number entered is in the array

      if(in_array($numWanted, $numArray) )

      {

        echo "YES";

      }

      else

  {

        echo "NO";

Try

<?php
$numWanted = trim($_POST['num_wanted']);
// create an array of numbers called $numArray
$numArray = array(12, 0, 89, 64, 23, 50);
?>
<?php
// use the array_search function to check if the number entered is in the array
      if(in_array($numWanted, $numArray) )
      {
        echo "YES";
      }
      else
     {
        echo "NO";
      }
?>

Your not posting the form data.

<form action="Ex4-04-test.php" method="get">

should be

<form action="Ex4-04-test.php" method="POST">
