displaying specific data from mysql table using php

[printline]

Hello All

I need a little help with a phph script to display some specific data from a mysql table.

I have a mysql table with 4 columns and 10 rows. I want to display fx. data from row 4, 6, 8 and 10.

I can display either the first row or all the rows using the below code:

[PHP]$row = mysql_fetch_arr ay($result) or die(mysql_error ());
echo $row['id']. " - ". $row['Thickness']. " <img src=images/arlon.jpg /> ". $row['Type']. " - ". $row['Sum'];
echo "<br />";[/PHP]

[PHP]while($row = mysql_fetch_arr ay($result)){
echo $row['id']. " - ". $row['Thickness']. " <img src=images/arlon.jpg /> ". $row['Type']. " - ". $row['Sum'];
echo "<br />";[/PHP]
}

Can someone tell me how to fetch a specific row of data......????? ?

I have tried with $row[2] but without any luck.....

Below is my entire code:

[PHP]<?
$username="xxxx xx";
$password="xxxx xx";
$database="prin tline";
$localhost="mys ql.webglobe.dk" ;

mysql_connect($ localhost,$user name,$password) ;
@mysql_select_d b($database) or die( "Unable to select database");
//$query="SELECT * FROM test";
$query="SELECT * FROM test3";
$result = mysql_query($qu ery) or die(mysql_error ());

$row = mysql_fetch_arr ay($result) or die(mysql_error ());
echo $row['id']. " - ". $row['Thickness']. " <img src=images/arlon.jpg /> ". $row['Type']. " - ". $row['Sum'];
echo "<br />";

$row[2] = mysql_fetch_arr ay($result) or die(mysql_error ());
echo $row['id']. " - ". $row['Thickness']. " <img src=images/arlon.jpg /> ". $row['Type']. " - ". $row['Sum'];
echo "<br />";

A row number is a meaningless concept in a database.
Do you mean a specific record?
If so then

SELECT * FROM test3 WHERE `id` = 4
OR `id` = 6 OR `id` = 8"

Hi,

You could streamline this with the use of 'in':

SELECT * FROM test3 WHERE `id` in (4,6,8)

But the idea of a row is not much use when you are selecting data out of a database.

If you want to display specific row then you need to use $row[nth column] ie, $row[0] or $row['column_name'].
For example,

while($row=mysql_fetch_result($query))
{
 echo $row['columnname'].'<br>';
}
