simple php pagination or css pagination with php/mysql - php

Question

I am trying to built a simple php pagination ( a sort of ).
or to be more specific css pagination with php/mysql.
Accessing and storing the values from db
while($row = $result->fetch_assoc()) {
$id[]=$row["id"];
$name[]=$row["name"];
$url[]=$row["url"];
//echo "id: " . $row["id"]. " - Name: " . $row["name"]. " " . $row["url"]. "<br>";
}
Displaying them
<ul class="pagination">
<li>«</li>
<?php
$i=1;
for ($x = 0; $x < count($id); $x++) { ?>
<li>
<a href=<?php echo "$url[$x]"; ?> target="iframe1"
title="<?php echo "$name[$x]"; ?>"><?php echo "$i";?></a>
</li>
<?php $i++;} ?>
<li>»</li>
</ul>
Once any number shown above is clicked required url is displayed inside iframe1
<div align="center">
<iframe name="iframe1" src="http://www.w3schools.com"
frameborder='0' height='1000' width='1000' align="center"></iframe>
</div>
when I click any number it display the url inside the iframe "iframe1" .
Question:
How do i display first and NEXT {NOT LAST} record in
<li>«</li> [First]
<li>»</li> [Next]
I am looking for a very small code to do the same.

Answer 1

The first link is pretty easy:
<a href=<?php echo "$url[0]"; ?> target="iframe1"
title="<?php echo $name[0]"; ?>"><<</a>
For next link It would kind of depend on how your urls are set out. If the $url values are just a name and your url is domain.com/blog?page=page1 where page1 is the value from $url then we get use $_GET['page'] to grab the current page. Then using:
$next = array_search($_GET['page'], $url);
will give us the number in the order of the current page so the next page will simply be $url[$next + 1]
EDIT:
OK if its a url that changes in domain part then the $_GET wont work. You could grab the current url using $_SERVER[REQUEST_URI] and then use the same technique as above to find its position in the array of urls.
