Examples of Oracle paging functions implemented by PHP, Phporacle page Instances

This article describes the Oracle paging function implemented by PHP. Share to everyone for your reference, as follows:

MySQL has limit, paging, we can use limit 30, 40, and Oracle has no limit, the other way to replace the--rownum.

First, the underlying method

/** * Data connection */function Connect ($db _user, $db _pwd, $db _name, $db _nls) {$this-&GT;DBH = Oci_connect ($db _user, $db _pwd, $db _na Me, $db _nls);} function GetAll ($query, $start =0, $rows =-1) {$this-&GT;DBH = emptyempty ($this->dbh)? $this->connect (): $this- >dbh; $this->sth = Oci_parse ($this->dbh, $query); Oci_execute ($this->sth, Oci_default) or $this->error ($this->sth, $query); Oci_fetch_all ($this->sth, $res, $start, $rows, OCI_FETCHSTATEMENT_BY_ROW+OCI_ASSOC); return $res;} /*** Get Pagination * * $query string query statement * $total int total number of bars * $page int pages * $rows int displayed per page * @return integer row number */funct Ion GetPage ($query, $total, $page, $rows =var_pagenav_rows) {$start _row = ($page-1) * $rows + 1; $start _row = $start _row > $total? 1: $start _row; $end _row = $start _row + $rows-1; $end _row = $end _row > $total? $total: $end _row;  $query = "SELECT * from" (select ROWNUM as Row_num, r.* from ($query) R where ROWNUM <= $end _row) where $start _row <= row_num "; REturn $this->getall ($query);} /*** gets the total number of rows for a query * * $string $sql Query statement * * Return integer Total row number */function GetCount ($sql) {$subSQL = ' select count (*) '. STRISTR ($s QL, ' from '); return $this->getone ($subSQL);} function GetOne ($query) {$row = $this->getrow ($query), if (Is_array ($row)) $one = current ($row), Else $one = "; Unset ( $row); return $one;} function GetRow ($query) {if (false = = = Stripos ($query, ' COUNT (')) {if (false = = = Stripos ($query, ' WHERE ')) {$query. = ' WHERE ROWNUM = 1 '; } else {$query. = ' and ROWNUM = 1 ';}} $result = $this->getall ($query, 0, 1); if (Emptyempty ($result)) $row = Array (); else $row = $result [0]; Unset ($result); return $row;}

Main two methods I write a little note

Ii. Method of Invocation

$total = $this->db->getcount ($sql); $result = $this->db->getpage ($sql, $total, $page, $page _number);

The above is just a part of the code, but also the core.
