If you have a textbox within a form that "POST"s the data then simply need to put something like:

 

<?php
// Function...
function writeName($var){
     return $var;
}

// Grab it.
$var = $_POST['textbox'];

// Send it to the function. 
echo writeName($var);
?>

 

Obviously changing the "textbox" with the actual name of the field.

Though my issue is being resolved just kindly answer my one last question

is it necessary to redirect our form page to a new page to get the posted value from textbox Can't we do it in the same page like

 

suppose the form for entering values is present at page 'name.php' and when i click on submit either than showing result on a new page its simply shows the output result in the same page that is name.php

 

NAme entered in 'name.php'

and also its acho in 'name.php' from the function mentioned above???

Written in PHP you would need to refresh the page so the data is actually sent in the first place regardless however if you wanted to enter the information into the textbox and send it to the function without refreshing or doing anything to the page you could do it using AJAX. Thats another kettle of fish though.
