<?php
$con=mysql_connect("localhost","root","admin");
mysql_query("set character_set_server='utf8'");
mysql_query("set names 'utf8'");
if(!$con)
{
	die('couldnot connect:');
}

mysql_select_db("santirino",$con);
@$user_id = $_POST['ID'];
echo "
<table class='bordered' align='center'> <thead> <tr> <th style='text-align:center;' nowrap='nowrap'> وقت الأنصراف </th> <th style='text-align:center;' nowrap='nowrap'> وقت الحضور </th> <th style='text-align:center;' nowrap='nowrap'> التاريخ </th> <th style='text-align:center;' nowrap='nowrap'> اسم العضو </th> <th style='text-align:center;' nowrap='nowrap'> رقم العضو </th> <th style='text-align:center; height='10px';' nowrap='nowrap'> المسلسل </th> </tr> </thead>
	";
echo $today = date("20y-m-d"). "   ";
$todayDate = date("Y-m-d g:i a");// current date
$currentTime = time($todayDate); //Change date into time
$timeAfterOneHour = $currentTime+60*60;

echo $time = date("H:i:s",$timeAfterOneHour);

if($time >= "16:00:00")
{
	$sql="select * from members where id = '$user_id'";
	$result = mysql_query($sql);
	
	$get_all="select * from attendance where date = '$today'";//select all members in current date
	$result_getall = mysql_query($get_all);
	$i;
	echo "<br />";
	while($row = mysql_fetch_array($result))
	{
		@$i++;
		mysql_query("set character_set_server='utf8'");
		mysql_query("set names 'utf8'");
		$query_sql = "INSERT INTO attendance (id,date,name,time) VALUES ('$user_id','$today','$row[name]','$time')";
		$res = mysql_query($query_sql);
		 echo "<tr>"
		 ."<td style='text-align:center;'><form><button>انصرف</button></form></td>"

There's a lot of code there. Which part are you having trouble with? I see code in there already to insert data into the database so I'm not sure what it is you're struggling with.
