Grab and echo out multiple SQL rows with PHP - php

Question

I'm wanting to fill a database with news article information such as PostID, PostTitle, PostDescription, PostContent and so on - I tried writing some code to constantly echo out the data in the SQL query but it only works for the first row that the query picks up
$SQL = "SELECT * FROM posts"; // get all info from posts
$result = mysql_query($SQL);
$row = mysql_fetch_array($result);
if (mysql_numrows($result) > 0) {
$row = mysql_fetch_array($result);
$Title = $row["PostTitle"];
$Description = $row["PostDescription"];
$Date = $row["PostDate"];
$AuthorID = $row["AuthorID"];
echo "<div id='preview'>";
echo "<div class='group selection'>";
echo "<div class='col span_1_of_3'>";
echo "<div id='previewmedia'>";
echo "</div>";
echo "</div>";
echo "<div class='col span_2_of_3'>";
echo "<h1>".$Title."</h1>";
echo "<p class='preview'>".$Description."</p>";
echo "<a href='bloglayout.php' class='orange readmore'>Read More...</a>";
echo "</div>";
echo "</div>";
echo "</div>";
}
I then thought about doing a SELECT query to then count the number of ID's in the table and then set that as $ID and then give each variable a number and then +1 after each loop but realised that wouldn't work so I'm kinda stuck on how to loop out several rows automatically from my database.
Also, I know I shouldn't be using mysql_numrows and whatnot in PHP and I should move to mysqli or PDO but this is for something where I've been asked to use mysql specifically.

You're only fetching one row. Try looping through your results.
$SQL = "SELECT * FROM posts"; // get all info from posts
$result = mysql_query($SQL);
while( $row = mysql_fetch_array($result);)
{
$Title = $row["PostTitle"];
$Description = $row["PostDescription"];
$Date = $row["PostDate"];
$AuthorID = $row["AuthorID"];
echo "<div id='preview'>";
echo "<div class='group selection'>";
echo "<div class='col span_1_of_3'>";
echo "<div id='previewmedia'>";
echo "</div>";
echo "</div>";
echo "<div class='col span_2_of_3'>";
echo "<h1>".$Title."</h1>";
echo "<p class='preview'>".$Description."</p>";
echo "<a href='bloglayout.php' class='orange readmore'>Read More...</a>";
echo "</div>";
echo "</div>";
echo "</div>";
}
