Asuming each record has a unique auto_incrementing id column, then

for all articles (latest first)
[code]$sql = "SELECT id, title FROM articles ORDER BY id DESC";[/code]

for latest x articles to be displayed

[code]$x = 10;
$sql = "SELECT id, title FROM articles ORDER BY id DESC LIMIT $x";[/code]


For the read more bit, output a link containing the id of the record in the querystring

[code]echo "a href='showmore.php?id=$id>Read more...</a>";[/code]

You still need to connect to your server and select the database, but as you are already writing to it I assume you know how to do that.

When the user clicks the "Read more..." link the page "showmore.php" (or whatever you want to call it) will be loaded and the id of the article is passed to it in the querystring. That page then has to query the database table, using the id value, to display the article contents in full.

One or many - depends on your coding style, for example

You can

[code]<?php
echo "<H1>$title<H1>
    <H3>Author : $author</H3>
    <p>$content</p>
    <p>Date : $article_date</p>";
?>    [/code]

or

[code]<H1><?php echo $title ?><H1>
<H3>Author : <?php echo $author ?></H3>
<p><?php echo $content ?></p>
<p>Date : <?php echo $article_date ?></p>[/code]

understanding this concept is what really opened php up for me.

on the show more page you have to run another query based on the id passed in the url
showmore.php?id=15


$id = $_GET['id']; //get the id from the querystring
$query = "SELECT * FROM table WHERE id = ". $id ."";

that query will return article number 15

Yes, you need to connect on each page that accesses the db

also barand do i need to use the code emehrkay gave me? The one that goes
$id = $_GET['id']; //get the id from the querystring
$query = "SELECT * FROM table WHERE id = ". $id ."";

Also would the code for showing latest article be
[code]$x = 1;
$sql = "SELECT id, title FROM articles ORDER BY id DESC LIMIT $x";[/code]
and if you had five variables in the article and you only wanted to show 2 of them with that latest one article code what would you add to that code?

You'll need code like emehrkay posted for getting that specific article from the "read more..." link.

In the SELECT clause try to avoid "SELECT * " as this will get all the columns and just specify the ones you actually need. The less data you pull from the database the quicker the query. Listing the actual columns also better documents what the query is doing if you come back to it later or if someone else needs to change something.

A series of articles by Kevin Yank got me started with PHP/MySQL - worth a read.
