meta tag system for a blog

Copy linkTweet thisAlerts:
Nov 04.2006

i have a ‘meta’ field in my blog which when i enter a blog i enter key words ‘rant php mysql’ etc… using a space as an identifier. currently i i haven’t been doing anything with this data. but now i want to split the words up and display them on the page in a list.

sounds easy…

but heres the bit i cant get my head round i don’t want duplicate data in the list.

i.e. more than one of my blogs will contain PHP or MYSQL but how would i stop these from looping again

[code=php]
$query = “SELECT meta FROM `blog`”;
$result = mysql_query($query) or die();
while ($row = mysql_fetch_assoc($result))
{
some function???
{
echo ‘<li><a href=”/blog/’.$meta.'”>’.$meta.'</a></li>’;
}
}
[/code]

thanks in advance

@bokehNov 04.2006 — [code=php]$query = "SELECT meta FROM blog";
$result = mysql_query($query) or die(mysql_error());
$meta_words = array();
if(mysql_num_rows($result) > 0)
{
while ($row = mysql_fetch_assoc($result))
{
if(preg_match_all('/w{3,}/', $row['meta'], $matches))
{
foreach($matches[0] as $meta_word)
{
$meta_words[$meta_word] = $meta_word;
}
}
}
}
sort($meta_words);
foreach($meta_words as $meta_word)
{
echo '<li><a href="/blog/'.$meta_word.'">'.$meta_word.'</a></li>';
}[/code]

@bokehNov 04.2006 — By the way that is case sensitive, although it could easily be changed!!!

Success!
