How about this instead, Mike?
?php
// some code
$fortune = mysql_query(SELECT text FROM fortunes ORDER BY RAND() LIMIT 1);
$fortune = mysql_fetch_row($fortune);
$fortune = sprintf(
'span class=quotecycquot;%squot;br /-Omniversalism.com/span',
$fortune[0]
);
// some more code
?
MySQL is implemented in random code, so it can probably perform this
operation faster, and this code is much cleaner. You may want to move
away from mysql since it's essentially deprecated. I have switched to
mysqli and prefer it.
a week ago or something like that there was an extensive discussion here
about ORDER BY RAND being slow and inefficient on large tables
