php pagination display 5pages range - php

Question

I use pagination using this tutorial.
Everything is ok, but I want to change display of page numbers.
The tutorial code generates pages link as below.
For page 1 : [1] 2 3 4 > >>
For page 6 : << < 3 4 5 [6] 7 8 9 > >> ( 3 pages range before and after).
What I want to change is showing only 5pages.
For page 1: [1] 2 3 4 5 > >>
For page 3: 1 2 [3] 4 5 > >>
For page 5: 1 2 3 4 [5] > >>
For page 6: << < [6] 7 8 9 10 > >>
For page 10: << < 6 7 8 9 [10] > >>
I think this part needs to be changed. I tried to search other articles but I couldn't find any. what is good logic to change? Thanks.
// loop to show links to range of pages around current page
for ($x = ($currentpage - $range); $x < (($currentpage + $range) + 1); $x++) {
// if it's a valid page number...
if (($x > 0) && ($x <= $totalpages)) {
// if we're on current page...
if ($x == $currentpage) {
// 'highlight' it but don't make a link
echo " [<b>$x</b>] ";
// if not current page...
} else {
// make it a link
echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$x'>$x</a> ";
} // end else
} // end if
} // end for
Added:
Last page also in 5 pages format
For page 1: [1] 2 3 4 5 > >>
For page 3: 1 2 [3] 4 5 > >>
For page 5: 1 2 3 4 [5] > >>
For page 6: << < [6] 7 8 9 10 > >>
For page 10: << < 6 7 8 9 [10] > >>
For last page 12: << < 8 9 10 11[12]
I am trying to put 5 pages numbers as group in array, to use with in_array. No success yet.
Added:
Somehow, I make it working... But current page is always in center which is not I wanted.. :(
// range of num links to show
//$range = 3;
$range = 2;
....
// Added from here...
if (($currentpage - $range) <= 1){
$start_x = 1;
$end_x = 5;
}
else if ($currentpage >= ($totalpages - $range)){
$start_x = $totalpages - 4;
$end_x = $totalpages;
}
else {
$start_x = $currentpage - $range;
$end_x = $currentpage + $range;
}
// Until here
// loop to show links to range of pages around current page
// for ($x = ($currentpage - $range); $x < (($currentpage + $range) + 1); $x++) {
for ($x = $start_x; $x < ($end_x + 1); $x++) {
// if it's a valid page number...
if (($x > 0) && ($x <= $totalpages)) {
// if we're on current page...
if ($x == $currentpage) {
// 'highlight' it but don't make a link
echo " [<b>$x</b>] ";
// if not current page...
} else {
// make it a link
echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$x'>$x</a> ";
} // end else
} // end if
} // end for
Result:
For page 1: [1] 2 3 4 5 > >>
For page 3: 1 2 [3] 4 5 > >>
For page 5: << < 3 4 [5] 6 7 > >>
For page 6: << < 4 5 [6] 7 8 > >>
For page 10: << < 8 9 [10] 11 12 > >>
For last page 12: << < 8 9 10 11[12]
I still want like..
For page 1: [1] 2 3 4 5 > >>
For page 3: 1 2 [3] 4 5 > >>
For page 5: 1 2 3 4 [5] > >>
For page 6: << < [6] 7 8 9 10 > >>
For page 10: << < 6 7 8 9 [10] > >>
For last page 12: << < 8 9 10 11[12]

// loop to show links to range of pages around current page
for ($x = 1; $x <= ($totalpages); $x++) {
// if it's a valid page number...
if (($x > 0) && ($x <= $totalpages)) {
//limit for each 5 pages
if ($x % 5 == 0) {
// if we're on current page...
if ($x == $currentpage) {
// 'highlight' it but don't make a link
echo " [<b>$x</b>] ";
// if not current page...
} else {
// make it a link
echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$x'>$x</a> ";
} // end else
}
} // end if
} // end for
