PHP Script to fetch new row from mysql on every script execution - php

Question

I have a simple my-sql table:
+----+----------+----------+-------------+-----------+
| id | Name | Father | National | Value |
+----+----------+----------+-------------+-----------+
| 1 | Daniel | David | American | 0 |
| 2 | Rebbeka | Craig | American | 0 |
| 3 | Robert | John | American | 0 |
| 4 | Arjun | Daneil | Indian | 0 |
| 5 | Ana | Peter | British | 0 |
+----+----------+----------+-------------+-----------+
I need to a php-script to query and fetch new single row every time it is executed. It may be based on ID.
About code/framework, i am using simple php5 with mysql on ubuntu server.
This is my code, the probelem is that it outputs whole of the Name,Father columns every time on call, i just want to print a single row everytime it is executed. and on every php script execution a new row should be printed based on id in ascending order.
<?php
$con = mysqli_connect('localhost','user','pass','database');
$result = mysqli_query($con,"select * from table");
while($row = mysqli_fetch_array($result)) {
echo "Name:" . $row['name'] . " " . "Father's Name:" . $row['father'];
echo "<br>";
}
mysqli_close($con);
?>
Every help is much appreciated.

Answer 1

the below code will help you get the output.
from next time when you ask any question pls add your code.
$link = mysqli_connect("localhost","root","","test") or die("Error " . mysqli_error($link));
$query = "SELECT * FROM `emp` ORDER BY RAND() LIMIT 0,1;" or die("Error in the consult.." . mysqli_error($link));
$result = mysqli_query($link, $query);
//display information:
$row = mysqli_fetch_array($result);
echo $row["name"].$row["Father"].$row["National"].$row["Value"];

As i have no much details of what type of code/framework you have I am giving you a answer on the basis of what I understand
There will be two ways I can think of to fetch the data
1.
Change the Table Structure and add one more column called lastFetched and every-time you fetch the row update the particular row by 1 and else everything else to 0 so that next time when you fetch the row you already know which is the last row fetched by you. and you can do an increment to it.
2.
On the page you are fetching the result would have a hidden input where you can store the last data number letz say first time it is 0 when page loads
then your query will be
SELECT * from <tablename> LIMIT 0,1
and increase the value of the hidden input to +1
so next time you fetch the result will gives the query
SELECT * from <tablename> LIMIT 1,2

From the discussion we had in the comments I came to a conclusion that you are looking for this.
<table>
<tr>
<?php
if(isset($_POST['pullNextRecord'))
{
$whtrec=$_POST['whatrecord'];
$con = mysqli_connect('localhost','user','pass','database');
$result = mysqli_query($con,"select * from table LIMIT $whtrec, ++$whtrec");
echo "<input type='hidden' name='whatrecord' value=".$whtrec." />";
echo "<th>Name</th><th>Fathers Name</th></tr><tr>";
while($row = mysqli_fetch_array($result))
{
echo "<td>$row['name']</td><td>$row['father']</td>";
}
mysqli_close($con);
}
?>
<input type="submit" name="pullNextRecord" />
