PHP pagination customize page number - php

Question

How to customize the pagination page number below?
Current:
and what I want is:
1 2 3 4 5 Next Last Page
Here is the PHP code:
for($i=1; $i<=$Num_Pages; $i++)
{
if($i != $Page)
{
echo "[ <a href='$_SERVER[SCRIPT_NAME]?Page=$i'>$i</a> ]";
}
else
{
echo "<b> $i </b>";
}
}
Any clue how to do this?

Answer 1

Could try this:
$Num_Pages = 70;
//$Page = $_GET['Page'];
$Page = 12;
$from = $Page - ($Page % 5) + 1;
for($i=$from; $i<$from+5 && $i<$Num_Pages; $i++)
{
if($i != $Page)
{
echo "[ <a href='$_SERVER[SCRIPT_NAME]?Page=$i'>$i</a> ]";
}
else
{
echo "<b> $i </b>";
}
}
$next_page = $Page+1;
echo "[ <a href='$_SERVER[SCRIPT_NAME]?Page=$next_page '>next</a> ]";
echo "[ <a href='$_SERVER[SCRIPT_NAME]?Page=$Num_Pages'>Last Page</a> ]";
Replace the $Page = 12 with the $_GET to get the page dynamically.
Haven't really tested it.

$start_page = intval($Page / 5) *5 + 1;
$to_page = $start_page + 4;
$is_last_group = ($start_page + 5)> $Num_Pages);
if (is_last_group)
$to_page = $Num_Pages;
for($i = $start_page; $i <= to_page; $i++)
{
if($i != $Page)
{
echo "[ <a href='$_SERVER[SCRIPT_NAME]?Page=$i'>$i</a> ]";
}
else
{
echo "<b> $i </b>";
}
}
if($page < $Num_Pages){
$next_page = $page + 1;
echo "[ <a href='$_SERVER[SCRIPT_NAME]?Page=$next_page '>next</a> ]";
echo "[ <a href='$_SERVER[SCRIPT_NAME]?Page=$Num_Pages'>last</a> ]";
}
