How do I change words in post texts?

[DonosOdD]

Hello again, and sorry for the late response (I haven't worked on the forum for some time).



Your answers were great, and I was able to do this:

PHP Code:

if ($forum['forumid'] != 2) 
{ 

    $pat = array(
    'f1',
        'f2',
        'f3',
        'f4',
        'f5',
        'f6',
        'f7',
        'f8',
        'f9',
        'f10'
         );
    

        $rep = array(
    'e1',
        'e2',
        'e3',
        'e4',
        'e5',
        'e6',
        'e7',
        'e8',
        'e9',
        'e10'
         );


    foreach ($pat as &$value) {
        $value = "/\b" . $value . "\b/iu" ;
    }


    $ret = preg_replace($pat, $rep, $this->post['message']);
    if ($ret !== NULL)
       $this->post['message'] = $ret;
} 


And it worked fine. However, my forum is in portuguese, and when I change something to a word with any accentuation, like ? or ?, the code changes nothing at all (I guess ret == null).



I'm bypassing it by writing the words without accentuation.

Any thoughts?


Thanks!


EDIT: It doesn't work. Well, it worked for a while, but after two tests and two F5s, it stopped working. I can't understand why. And I was using this exact code, with this silly words.
