PHP分页与范围

Question

我有一个分页脚本，它工作正常。我想在我的分页中添加一个范围。但是它应该采用以下格式；

>>

当我点击“5”时，应该是；

>>

同理，点击“8”，应该是；

>>

假设“11”是最后一页，如果我们点击 11，它应该是；

>>

我的代码是这样的；

    $recordLimit = 4;

    $totalNumberofRecords = 100;

    $currentpage = !empty( $startPage ) ? (int) $startPage : 1 ;

    $startFrom = ( $currentpage -1 ) * $recordLimit;

    $limit =  $startFrom.','.$recordLimit;

    $totalPages = ceil( $totalNumberOfRecords / $recordLimit );

    $j = 0;

    for ($i = max(1, $currentpage - 1); $i<= min($currentpage + 4, $totalPages); $i++) {

 $fairLists['pages'][$j] = $i;

if ( $startPage == $fairLists['pages'][$j] ||  ( $j == 0 && empty( $startPage ) ) 
   {
    $fairLists['pages'][$j] = array( $i ,"font-weight:bold;");
}else{
    $fairLists['pages'][$j] = array( $i , 'font-weight:normal;' );
}
$j++;

}

我想将范围限制为 5，当我们到达范围时，它应该显示 1 条上一条记录和 3 条下一条记录；

如果有人知道脚本，请帮助我，

谢谢，

阿伦

您的问题已由我解决。我的代码如下，但在使用此代码后，如果它适用于您，请点击此评论作为答案..... 代码如下

<php
$page = isset($_GET['page']) ? $_GET['page'] : 1;
$recordsPerPage = 10;
$fromRecordNum = ($recordsPerPage * $page) - $recordsPerPage;

$query = "SELECT * FROM
        table_mstr_department
        ORDER BY DeptId
      LIMIT 
        {$fromRecordNum}, {$recordsPerPage}";


  $stmt = $con->prepare( $query );
  $stmt->execute();
  $num = $stmt->rowCount();


  echo "<div id='search_area'>";
        echo "<table width='100%' border='0' cellspacing='0' cellpadding='0'>";
                echo "<tr>";
                    echo "<td colspan='3'></td>";
                echo "</tr>";

                echo "<tr>";
                //********Add New Department Button
                    echo "<td  height='auto' width='auto'>";
                        echo "<input type='submit' name='newemp' value='Add New Department'>";
                     echo "</td>";
                    echo  "<td width='auto'></td>";

                    //******Search Button
                    echo "<td width='auto'>";
                            echo "<div id='search_options'>";

                                    echo "<input type='button' name='search_btn' value='Search' />";

        else 
        {
         $bgcolor= "#A2B5CD";
        }
        //extract row, this will make $row['firstname'] to just $firstname only
        extract($row);

        //creating new table row per record
