這篇文章主要介紹了thinkPHP統(tǒng)計排行與分頁顯示功能,結(jié)合實例形式分析了thinkPHP數(shù)據(jù)庫查詢與結(jié)果分頁顯示相關(guān)操作技巧,需要的朋友可以參考下

本文實例分析了thinkPHP統(tǒng)計排行與分頁顯示功能。分享給大家供大家參考，具體如下：

1.分頁參數(shù)

count	總數(shù)
firstRow	起始行
listRows	每一次獲取記錄數(shù)
list	每一頁的記錄（要與count對應(yīng)一致就行）

2.分頁對象

可以針對真實的數(shù)據(jù)表
也可以針對統(tǒng)計出來的數(shù)據(jù)表，或者說是虛擬的表
因為LIMIT是最后執(zhí)行的，哪怕你進行g(shù)roup操作，哪怕你進行子查詢

    $thisyear = date('Y');
    if ($thismonth == 1) {
      $lastmonth = 12;
      $lastyear = $thisyear - 1;
    } else {
      $lastmonth = $thismonth - 1;
      $lastyear = $thisyear;
    }
    $lastStartDay = $lastyear . '-' . $lastmonth . '-1';
    $lastEndDay  = $lastyear . '-' . $lastmonth . '-' . date('t', strtotime($lastStartDay)); //t 給定月份所應(yīng)有的天數(shù),28到31

}

這里用的是thinkphp的分頁類實現(xiàn)的。
