str_replace() problems

Hi Folks,

In the message forum I have built, I have added str_replace to void out naughty words!!! (LOL)

Here is what I have:


$result = mysql_db_query($db, "SELECT * FROM words WHERE id>0");
while ($row = mysql_fetch_array($result)) {
$word = $row["word"];
$message = str_replace($word,"****",$message);
}


Problem is, lets say the value of $word = cat. If the $message has 'cat' in it then it replaces it with '****'. Problem is, if the message contains 'Cat' or 'cat!' etc it won't replace it!

Is there any way around this other than say making the entire message lower case.

Thanks in advance! :thumbsup:

Try this code instead:

$result = mysql_db_query($db, "SELECT * FROM words WHERE id>0");
while ($row = mysql_fetch_array($result)) {
$word = $row["word"];
$message = preg_replace("/($word)/i","****",$message);
}

Or just use the case insensitive version of str_replace may be?


$result = mysql_db_query($db, "SELECT * FROM words WHERE id>0");
while ($row = mysql_fetch_array($result)) {
$word = $row["word"];
$message = str_ireplace($word,"****",$message);
}

Way to revive a 7 year old thread! haha, but you do have a point - your solution to the problem was a lot better than preg_replace.

They joined for that? - a 7 year old thread?.. well.. thats dedication i suppose!
