onClick - selected (clicked) value in input box - php

Question

i am retrieving data form database using a search query.
PHP code (which I'm using in search query to display search results)
echo "<span style='background-color= #FFFF00'>$query</span><br>";
$count=$dbo->prepare($query);
$count->execute();
$no=$count->rowCount();
if($no > 0 ){echo " <span>No of records = ".$no."</span>";
echo "<table><tr><th>PHONE NUMBER</th><th>OWNER NAME</th></tr>";
foreach ($dbo->query($query) as $row){
echo "<tr><td>$row[ROLLNO]</td><td>$row[CNAME]</td></tr>";
}
echo "</table>";
i want to do like this,
when a user clicks on a phone number, it should redirect to a new page and in that new page, my input box should be filled with this phone number and should be submitted.
Input Box Code (which I'm using in page 2)
<form name="phone_number_form" id="phone_number_form" action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post" onsubmit="return vali()" >
<input type="text" name="number" id="number" />
<input type="submit" name="submit" value="Submit" />
</form>

Looking at w3schools PHP has a $_POST variable which is used to collect values from a form sent with method="post". There's also $_GET and $_REQUEST which seems to merge both post and get data. http://www.w3schools.com/php/php_post.asp
There are a couple of options like making a request (get) from your first page or post the data from your first page.
REQUEST Method
Heres how I think the request way to do it would work
PAGE 1
Amend the foreach that renders the table row to include an hyperlink to your second page
foreach ($dbo->query($query) as $row){
echo "<tr><td>$row[ROLLNO]</td><td>$row[CNAME]</td></tr>";
}
PAGE 2
Amend the textbox to be populated with the phone number from the request variable
<input type="text" name="number" id="number" value="<?php echo $_REQUEST["phoneno"]; ?>" />
POST Method
In your first page using javascript when the user clicks the phone number set a hidden field and submit the form to the second page. Again you should be able to read the hidden fields value from the $_REQUEST variable
