ok, I found the COUNT statement, however I'm not sure how to use the output.
Here's my code (I just guessed at how it might work):
<?php
$query="SELECT COUNT(*) FROM [table_name]";
$result=mysql_query($query);
$num=mysql_numrows($result);
$i=0;
while ($i < $num) {
$Total=mysql_result($result,$i,"COUNT");
++$i;
}
echo "There are currently $Total cars in the database.";
?>
