PHP / MySQL Database Optimization Function
After frequent record deletion from your MySQL database tables, your tables can acquire overhead. Overhead is empty space left inside the database table due to the deletions. A great way to speed up your MySQL database, not to mention keep it compact, is to use a simple PHP function to optimize your database tables:
/* OPTIMIZE ALL TABLES */
function optimize_database($DATABASE_LINK) {
$result = mysql_query('SHOW TABLES', $DATABASE_LINK) or die('Cannot get tables');
while($table = mysql_fetch_row($result)) {
mysql_query('OPTIMIZE TABLE '.$table[0], $DATABASE_LINK) or die('Cannot optimize '.$table[0]);
}
}
I use the $DATABASE_LINK variable to keep my connection throughout my PHP script. Obviously it's not required, so you can modify the above function if you don't keep that variable.

With a PHP script, you can have it as a stand alone (with connection info), or you can put it as part of your code, as I have.
Great script. I was looking for a way to compact a MySQL database, and this is perfect. Thanks.
This article is like my ass,
its big shit
@trimd: hei trimd, you so stupid!
if you want fast compact you can make a program with delphi or VB6 to compact it. i make a application to compact my mysql database 370MB (7years period) become 90MB. Look more carefully trimd.
make a little application to compact it, use Delphi or VB6
don’t look others samples
grow trimd !
for more explanation go to mysql site.
or dev forum for VB
try to become great programmer.
not like junior!
Thanks, for the scripts because so far I have only seen two, the one for backing up the tables and this one above. They all look to be great and I’m use them in the my project.
Thanks. I grabbed this code and created a WP plugin. Thanks again. :-)
