[PHP] How would I go about doing this?

Hi,

I have a table with 20,000 odd rows. Every row has a 'title', such as "hello there" or "my name is bob", as an example. What I want to do is to grab these titles, put a dash ( - ) between the spaces and then insert these titles with dashes into the table under 'dashed'.

So for example, I have these under title:

hello there mate
how are you
its cool yeah
fun fun fun
food tastes good
lets get some cola
good idea mate

And then the PHP script does what I said above and turns them into...

hello-there-mate
how-are-you
its-cool-yeah
fun-fun-fun
food-tastes-good
lets-get-some-cola
good-idea-mate

I'm not great at PHP but I imagine explode would be used? Any help?

Thanks!

Either using a loop in PHP (untested):

PHP Code:

---

<?php
/* Assuming you've already connected to the DB */

// Get rows
$query=mysql_query("SELECT * FROM `items`;");
while($row=@mysql_fetch_array($query)){
     $newTitle=str_replace(" ","-",$row['title']); // Generate new title
     mysql_query("UPDATE `items` SET `dashed`='{$newTitle}' WHERE `title`='".mysql_real_escape_string($row['title'])."';"); // Query the database
}
echo "All done.";
?>

---

Or a much more efficient, all-in-one query method (untested):

PHP Code:

---

<?php
/* Already connected */
mysql_query("UPDATE `items` SET `dashed`=REPLACE(`title`,' ','-');");
?>
