Question

Basically, I’m trying to create a function in php that would give me the most recent column (message) that has no word greater than 40 characters. I was able to get the most recent message but I have no idea how to only get the most recent message that has no word greater than 40 characters. Please refer to the $callrecent variable.

<?php
function recentpost($postnum) {
$callrecent = "SELECT message FROM messages WHERE message (HAS NO WORD GREATER THAN 40 CHARACTERS) ORDER BY msg_id DESC LIMIT $postnum,1";

$callrecent_run = mysql_fetch_assoc(mysql_query($callrecent));

$message = stripslashes($callrecent_run['message']);

return $message;
}
?>

Answer 1

you could use regular expressions

SELECT message
FROM messages
WHERE message not regexp '[[:alnum:]]{41}'
ORDER BY msg_id DESC
LIMIT $postnum, 1
