Php self-written nice paging class

A nice paging class written by php itself is not complete. it is not verified in some cases, but can be used. for the paging effect, see the bottom of the article. Except for the code that links to the database, all the other codes are pasted. For learning and use ~

 PageSize = $ pageSize; 19 $ this-> showPage = $ showPage; 20 $ this-> count = $ count; 21 $ this-> page = $ this-> checkPage ($ currentPage); 22 $ this-> mergyStr = ''; 23 $ this-> skip = $ skip; 24} 25 26 // check the validity of the passed $ page 27 public function checkPage ($ currentPage) {28 if ($ currentPage <1 | empty ($ currentPage )) {29 $ currentPage = 1; 30} 31 if ($ currentPage> $ this-> totalPages () {32 $ currentPage = $ this-> totalP Ages (); 33} 34 return $ currentPage; 35} 36 37 // calculates the offset 38 public function pageOffset () {39 return ($ this-> showPage-1)/2; 40} 41 42 // calculate the total number of pages 43 public function totalPages () {44 return ceil ($ this-> count/$ this-> pageSize ); 45} 46 47 // get the page URL 48 public function getPageUrl () {49 $ CurrentUrl = $ _ SERVER ["REQUEST_URI"]; 50 $ arrUrl = parse_url ($ CurrentUrl ); 51 $ urlQuery = $ arrUrl ["query"]; 52 53 if ($ u RlQuery) {54 // print_r ($ this-> page); 55 $ urlQuery = preg_replace ("/(^ | &) page = /". $ this-> page, "", $ urlQuery); 56 $ CurrentUrl = str_replace ($ arrUrl ["query"], $ urlQuery, $ CurrentUrl ); 57 58 if ($ urlQuery) {59 $ CurrentUrl. = "& page"; 60} 61 else $ CurrentUrl. = "page"; 62 63} else {64 $ CurrentUrl. = "?

"; 132 133 print_r ($ this-> mergyStr); 134} 135 136 // jump page 137 public function skipNumPage () {138 $ this-> mergyStr. = ""; 142} 143 144}

The above is all the code of the class file, and the following is the call instance:

 "; Echo"Follow_trade_idFollow_id"; While ($ rs = mysql_fetch_assoc ($ query) {echo"{$ Rs ['Follow _ trade_id ']}{$ Rs ['Follow _ id']}";} Echo""; // Read the pagination bar $ p-> GetPagerContent ();
