I am new to PHP (in-fact I am learning it). I am trying to get the value of textbox defined in HTML and print it on HTML page through PHP code. I am able to send the value of textbox to another page using form post and getting it using $_POST['name'] on other page.

I am not able to print the value of textbox on same page.

Here is my code:

<html>
    <head>
        <?php

            function myfunction()
            {
                printf($_POST['fname']);
            }

        ?>
    </head>

    <body>

        Name: <input type="text" name="fname" />

        <input type="button" onClick="myfunction()" value="Click" />

    </body>
</html>

    First of all it’s not required to write php function within <head> tags. Second,
    you can’t POST data without <form> tags. try this

    <?php
if(isset($_POST['submit']) && $_POST['submit']=='Submit'){
     $name=$_POST['fname'];
     echo $name;
     }
else {  
        ?>
<html>
    <head>

    </head>

    <body>
<form method="POST" action="<?=$_SERVER["PHP_SELF"]?>">
        Name: <input type="text" name="fname" />

        <input type="submit" name="submit" value="Submit"/>
</form>
    </body>
</html>
<?php } ?>
