php中间值,比较当前值和下一个值,并在中间推送数组(Adodb)PHP

我有一个用AdodbConn从表中选择的函数,问题是如何将当前值与循环中的下一个值进行比较。因为我必须在当前值和下一个值之间推一个值。

public function list()

{

$errMsg = "";

$recPerPage = 15;

$currPage = 1;

$where = "";

$filter_user="";

// $user_level = 0[Admin] 1[user]

if(isset($_GET["pagenum"]))

$currPage = intval($_GET["pagenum"])+1;

if(isset($_GET["pagesize"]))

$recPerPage = intval($_GET["pagesize"]);

$this->load->library('AdodbConn');

$conn = $this->adodbconn->getOraConn("WF");

$this->load->helper('erp_wb_helper');

if(isset($_GET["filterscount"]))

$where = genJQWFilterSQL($this->initGrid());

$query="select NO_DOK ID,NO_DOK,JDOK

from TBTR_VIEW5

where TR like '".$this->session->userdata('TMP_KS')."'

and TK like'".$this->session->userdata('TMP_RT')."' ".

$where."

order by CREATED_DATE desc";

$arrParamData = array();

$rst=$conn->PageExecute($query,$recPerPage,$currPage,$arrParamData);

if($rst){

$total_rows = $this->adodbconn->gettotalrec($conn, $query, $arrParamData);

if($rst->recordCount()>0){

for($i=0;$irecordCount();$i++){

//Compare here current no_dok with next no_dok

$arrData[] = array(

'ID' => $rst->fields["ID"],

'NO_DOK' => $rst->fields["NO_DOK"],

'JDOK' => $rst->fields["JDOK"]

);

$rst->moveNext();

}

}else{

$total_rows = 0;

$arrData[] = array(

'ID' => "",

'NO_DOK' => "",

'JDOK' => ""

);

}

}else{

$total_rows = 0;

$arrData[] = array(

'ID' => "",

'NO_DOK' => "",

'JDOK' => ""

);

}

//$errMsg = $query;

$data[] = array(

'where' => $where,

'TotalRows' => $total_rows,

'Rows' => $arrData,

'ErrorMsg'=>$errMsg

);

print_r(json_encode($data,JSON_PRETTY_PRINT));

}

我试过几种方法,比如:

for($i=0;$irecordCount();$i++){

if($rst[$i]->fields["NO_DOK"]==1 && $rst[$i+1]->fields["NO_DOK"]==3){

//

}

}

但没用。
