Let's take a look at it first:

 

 

For more paging effects, there are many such styles in the php100 Forum. here we will share the CSS style code in the image:

CSS:

 
 

  
  
DIV.digg {PADDING-RIGHT: 3px; PADDING-LEFT: 3px; PADDING-BOTTOM: 3px; MARGIN: 3px; PADDING-TOP: 3px; TEXT-ALIGN: center}  
  
  
DIV.digg A {BORDER-RIGHT: #aaaadd 1px solid; PADDING-RIGHT: 5px; BORDER-TOP: #aaaadd 1px solid; PADDING-LEFT: 5px; PADDING-BOTTOM: 2px; MARGIN: 2px; BORDER-LEFT: #aaaadd 1px solid; COLOR: #000099; PADDING-TOP: 2px; BORDER-BOTTOM: #aaaadd 1px solid; TEXT-DECORATION: none}  
  
  
DIV.digg A:hover {BORDER-RIGHT: #000099 1px solid; BORDER-TOP: #000099 1px solid; BORDER-LEFT: #000099 1px solid; COLOR: #000; BORDER-BOTTOM: #000099 1px solid}  
  
  
DIV.digg A:active {BORDER-RIGHT: #000099 1px solid; BORDER-TOP: #000099 1px solid; BORDER-LEFT: #000099 1px solid; COLOR: #000; BORDER-BOTTOM: #000099 1px solid}  
  
  
DIV.digg SPAN.current {BORDER-RIGHT: #000099 1px solid; PADDING-RIGHT: 5px; BORDER-TOP: #000099 1px solid; PADDING-LEFT: 5px; FONT-WEIGHT: bold; PADDING-BOTTOM: 2px; MARGIN: 2px; BORDER-LEFT: #000099 1px solid; COLOR: #fff; PADDING-TOP: 2px; BORDER-BOTTOM: #000099 1px solid; BACKGROUND-COLOR: #000099}  
  
  
DIV.digg SPAN.disabled {BORDER-RIGHT: #eee 1px solid; PADDING-RIGHT: 5px; BORDER-TOP: #eee 1px solid; PADDING-LEFT: 5px; PADDING-BOTTOM: 2px; MARGIN: 2px; BORDER-LEFT: #eee 1px solid; COLOR: #ddd; PADDING-TOP: 2px; BORDER-BOTTOM: #eee 1px solid} 
 
 

PHP code:

 
 

  
  
 
  
  
$ Contents = "fjka; fjsa; # page # Generate [newpage] # page # component writing # page # parts and add # page # Paging code "; // original content with paging labels
  
  
$ Cons = "fjka; fjsa; adsfasdfas code"; // The original content without the paging tag
  
  
 
  
  
Function conpage ($ contents ){
  
  
$ Pagesss = '# page #'; // sets the page tag.
  
  
$ A = strpos ($ contents, $ pagesss );
  
  
If ($ ){
  
  
$ Con = explode ($ pagesss, $ contents );
  
  
$ Cons = count ($ con );
  
  
@ $ P = ceil ($ _ GET ['P']);
  
  
If (! $ P | $ p <0) $ p = 1;
  
  
$ Url = $ _ SERVER ["REQUEST_URI"];
  
  
$ Parse_url = parse_url ($ url );
  
  
$ Url_query = $ parse_url ["query"];
  
  
If ($ url_query ){
  
  
$ Url_query = ereg_replace ("(^ | &) p = $ p", "", $ url_query );
  
  
$ Url = str_replace ($ parse_url ["query"], $ url_query, $ url );
  
  
If ($ url_query) $ url. = "& p"; else $ url. = "p ";
  
  
} Else {
  
  
$ Url. = "? P ";
  
  
}
  
  
If ($ cons <= 1) return false; // only one page is displayed without pagination
  
  
$ Pagenav = "";
  
  
For ($ I = 1; $ I <= $ cons; $ I ++ ){
  
  
If ($ I = $ p ){
  
  
$ Pagenav. = ''. $ p .'';
  
  
} Else {
  
  
$ Pagenav. = "$ I ";
  
  
}
  
  
}
  
  
$ Pagenav. = "";
  
  
Return $ con [$ P-1]. $ pagenav;
  
  
} Else {
  
  
Return $ contents;
  
  
}
  
  
}
  
  
 
  
  
Echo conpage ($ contents ); //
  
  
Echo conpage ($ cons); //
  
  
 
  
  
?>
