{SOLVED} PHP trim whitespaces

[bhing]

hiya!!!
I have a php program that retrieve data from the database. The result is not consistent, i mean, there are many whitespaces in between characters. Like cs 143, the result will look like "cs 143", my problem is i want to have a single space in between it.. help pls..
tnx

Your message appears to only have a single spacing, but hopefully this will help.
str_replace($fi nd, $replace, $str);
so you can use it as
$entry = (" ", " ", $entry);

When you display the string in HTML it does not really matter, because the browser will remove extraneous blanks. When you want to use the data to store or other non-display function, you'll need a loop to remove all blanks except just 1. A lot easier is to use a logical expression. See the following snippet and run it, so you'll see the result.
[php]<?php
$data = "A B C D E F G";
echo '<br><pre>';
var_dump($data) ;
// result: string(30) "A B C D E F G"
$data = preg_replace('/(\\s+)/', ' ',$data);
echo '<br><pre>';
var_dump($data) ;
// result: string(13) "A B C D E F G"
?>[/php]

i got my idea though your suggestions...
actually i used ereg_replace function....

ereg_replace(" +"," ",$query["courseid"]);
