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");
     ?>
