PHP uses the array function to implement paging, Phparray function paging

The code is simple, so there's no more nonsense.

The

copy Code code is as follows:
$array =array ("1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12", "13", "14", "15", "16", "17", "18", "19", "20");//Specify the array to be paged
$page = $_get[' page '];
$r = $this->page ($array, 5, $page);
Print_r ($R);
exit ();
foreach ($r ["source"] as $s) {
echo $s;
}
Function page ($array, $pagesize, $current) {
$_return=array ();
$total =ceil (Count ($array)/$pagesize);// Total pages
$prev = (($current-1) <=0? "1":($current-1));//Determine the previous page, if the current page is the first page, click to display the first page
$next = (($current + 1) >= $total? $total: $current + 1);//Determine the next page, If the current page is the last page, click on the next page to display the last page
$current = ($current > ($total)? ( $total): $current);//If the current page is greater than the total number of pages, the current page is the last page
$start = ($current-1) * $pagesize;//When pagination is displayed, how many messages should start reading
for ($i = $start , $i < ($start + $pagesize), $i + +) {
Array_push ($_return, $array [$i]);//Put the displayed information into the array $_return
}
$pagearray [ "Source"]=$_return;
$pagearray ["page"]= "first \" >prev next end;//the page style can be adjusted as needed
return $pagearray;
}

The above is the use of the array function to achieve the core of paging code, I hope you can like.
