如何通过分页从我的mysql数据库表中每页只显示5条记录?

I want to display five record per page through pagination (mysql,php,html,css) until all the records are displayed, navigation to pages must be like, Page: 1 2 3 4 5 6 7 7 8... Last.

HERE IS MY CODE TO VIEW ALL THE RECORDS FROM emp_master table. I am new to PHP so please write an easily understandable code for pagination. I have seen few examples but they are not working.

<?php
$con=mysqli_connect("localhost","user","password","dataplus");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}

$result = mysqli_query($con,"SELECT * FROM emp_master");

echo "<table border='1'>";

$i = 0;
while($row = $result->fetch_assoc())
{
if ($i == 0) {
  $i++;
  echo "<tr>";
  foreach ($row as $key => $value) {
    echo "<th>" . $key . "</th>";
  }
  echo "</tr>";
 }
 echo "<tr>";
 foreach ($row as $value) {
  echo "<td>" . $value . "</td>";
 }
 echo "</tr>";
 }
 echo "</table>";

  mysqli_close($con);

I want to display five record per page through pagination untill all the records are displayed, navigation to pages must be like, Page: 1 2 3 4 5 6 7 7 8... Last.

This code below is not working:

     $dbhost="localhost";
     $dbuser="10053"; 
     $dbpass="n6867242"; 
 $database="0368";

     $rec_limit = 10;
     $conn = mysql_connect($dbhost, $dbuser, $dbpass);

     if(! $conn ) {
        die('Could not connect: ' . mysql_error());
     }
     mysql_select_db('1005368');

     /* Get total number of records */
     $sql = "SELECT count(emp_id) FROM emp_master ";
     $retval = mysql_query( $sql, $conn );

     if(! $retval ) {
        die('Could not get data: ' . mysql_error());
     }
     $row = mysql_fetch_array($retval, MYSQL_NUM );
     $rec_count = $row[0];

     if( isset($_GET{'page'} ) ) {
        $page = $_GET{'page'} + 1;
        $offset = $rec_limit * $page ;
     }else {
        $page = 0;
        $offset = 0;
     }

     $left_rec = $rec_count - ($page * $rec_limit);
     $sql = "SELECT emp_id, emp_name, e_mail ". 
        "FROM emp_master ".
        "LIMIT $offset, $rec_limit";

     $retval = mysql_query( $sql, $conn );

     if(! $retval ) {
        die('Could not get data: ' . mysql_error());
     }

     while($row = mysql_fetch_array($retval, MYSQL_ASSOC)) {
        echo "EMP ID :{$row['emp_id']}  <br> ".
           "EMP NAME : {$row['emp_name']} <br> ".
           "EMP MAIL : {$row['e_mail']} <br> ".
           "--------------------------------<br>";
     }

     if( $page > 0 ) {
        $last = $page - 2;
        echo "<a href = \"$_PHP_SELF?page = $last\">Last 10 Records</a> |";
        echo "<a href = \"$_PHP_SELF?page = $page\">Next 10 Records</a>";
     }else if( $page == 0 ) {
        echo "<a href = \"$_PHP_SELF?page = $page\">Next 10 Records</a>";
     }else if( $left_rec < $rec_limit ) {
        $last = $page - 2;
        echo "<a href = \"$_PHP_SELF?page = $last\">Last 10 Records</a>";
     }

     mysql_close($conn);

    IF your are using mysqli the code is below

     $conn=mysqli_connect("localhost","root","","ui");
    
    
     $start=0;
      $limit=5;
    
      $t=mysqli_query($conn,"select * from form_table");
      $total=mysqli_num_rows($t);
    
    
    
       if(isset($_GET['id']))
       {
            $id=$_GET['id'] ; 
                            $start=($id-1)*$limit;
    
                              }
                else
                {
            $id=1;
       }
       $page=ceil($total/$limit);
    
       $query=mysqli_query($conn,"select * from form_table limit                                        $start, $limit");

    i Give you an example of my project of pagination. Just you have to put your values in the code
    
    $sql="SELECT * FROM tblname  LIMIT  $next,5";
    $results = mysqli_query($conn,$sql);
        }
            else if (isset($_POST['prev']))
            {
                $prev1=$_POST['prev'];
                $next=$_POST['prev'];
                $prev=$prev1;
                $sql="SELECT * FROM tablename  LIMIT  $prev,5";
                $prev=$prev1;
                $results = mysqli_query($conn,"SELECT * FROM tablename LIMIT  $prev,10");   
                    if($prev==0)
                    {
                        $prev = 0;
                    }
                    else
                    {
                        $prev=$next-10;   
                    }
            }
            else
            {
                $next=0;
                $prev=0;
                $results = mysqli_query($conn,"SELECT * FROM tablename LIMIT  $next,10");
            }

    Link is here for demo, click here to experience the result

    Here is the code working for me, just change your db name, username and password and get pagination done. You can change $rec_limit value to your desired no. of records per page.

    <?php 
      $host="localhost";
      $username="68"; 
      $password="67242"; 
      $database="68";
    
       $rec_limit = 5;
        $conn = mysql_connect($localhost,$username,$password);
    
        if(! $conn ) {
        die('Could not connect: ' . mysql_error());
     }
     mysql_select_db('10');
    
     /* Get total number of records */
     $sql = "SELECT count(emp_id) FROM emp_master ";
     $retval = mysql_query( $sql, $conn );
    
     if(! $retval ) {
        die('Could not get data: ' . mysql_error());
     }
     $row = mysql_fetch_array($retval, MYSQL_NUM );
     $rec_count = $row[0];
    
     if( isset($_GET{'page'} ) ) {
        $page = $_GET{'page'} + 1;
        $offset = $rec_limit * $page ;
     }else {
        $page = 0;
        $offset = 0;
     }
    
     $left_rec = $rec_count - ($page * $rec_limit);
     $sql = "SELECT eid,ename, email, quali, gender, contactno, birthdate, joiningdate,CURDATE(), TIMESTAMPDIFF( YEAR, birthdate, CURDATE( ) ) AS age ". 
        "FROM emp_master ".
        "LIMIT $offset, $rec_limit";
    
     $retval = mysql_query( $sql, $conn );
    
     if(! $retval ) {
        die('Could not get data: ' . mysql_error());
     }
    
    
      echo "<table border='1'>";
      $i = 0;
      while($row = mysql_fetch_array($retval, MYSQL_ASSOC)) {
    
       if ($i == 0) {
            $i++;
            echo "<tr>";
            foreach ($row as $key => $value) {
              echo "<th>" . $key . "</th>";
            }
            echo "</tr>";
            }
            echo "<tr>";
            foreach ($row as $value) {
            echo "<td>" . $value . "</td>";
           }
          echo "</tr>";
    
         }
        echo "</table>";
    
    if( $page > 0 ) {
    $last = $page - 2;
    echo "<a href = \"$_PHP_SELF?page=$last\">Last 5 Records</a> | ";
    echo "<a href = \"$_PHP_SELF?page=$page\">Next 5 Records</a>";
    
    }else if( $page == 0 ) {
    $page = $page + 0;
    echo "<a href = \"$_PHP_SELF?page=$page\">Next 5 Records</a>";
    
    }else if( $left_rec < $rec_limit ) {
    
    $last = $page - 2;
    echo "<a href = \"$_PHP_SELF?page=$last\">Last 5 Records</a>";
    
    }
    
         mysql_close($conn);
    php?>

    you just should remove spaces in href and also make $page = $page + 1 when page is 0

    if( $page > 0 ) {
        $last = $page - 2;
        echo "<a href = \"$_PHP_SELF?page=$last\">Last 10 Records</a> |";
        echo "<a href = \"$_PHP_SELF?page=$page\">Next 10 Records</a>";
     }else if( $page == 0 ) {
        $page = $page + 1;
        echo "<a href = \"$_PHP_SELF?page=$page\">Next 10 Records</a>";
     }else if( $left_rec < $rec_limit ) {
        $last = $page - 2;
        echo "<a href = \"$_PHP_SELF?page=$last\">Last 10 Records</a>";
     }

    If you want just PHP MySQL code, I usually use something like the following.

    $page=max(intval($_GET['page']),1); // assuming there is a parameter 'page'
    $itemsperpage = 5;
    $total=100; // total results if you know it already otherwise use another query
    $totalpages = max(ceil($total/$itemsperpage),1);
    $query = "SELECT * FROM emp_master LIMIT ".(($page-1)*$itemsperpage).",".$itemsperpage; // this will return 5 items based on the page

    You can use a library called dataTables that will auto paginate the data and you can easily customize it to suit your needs with the look and how many records to show per page. It also has a search field which enables users to search your data without any extra code.

    All you have to do is include a couple of cdn's and the following code and everything works fine

    $(document).ready(function(){
        $('#myTable').DataTable();
    });
    

    Some examples here
