Sarching a string, not strstr??

[AbydosGater]

Hey, Ive been working on a chat script for my website, its going great, but my members have been asking me to add a similies set to chat!
And i said yeah it would be easy..
All i have to do is check if the string contains one of the keywords, (ie : P) and then if it does use str_replace?, as far as i know thats correct!

But how would i search if my string contains the keyword?
I was going to use strstr, but on reading the manual i relised that this only...

"Returns part of haystack string from the first occurrence of needle to the end of haystack. "

What should i use?

Thanks Abydos

Why not use the str replace function?

for example,

$string = "im great :) oh yes";

$newstring = str_replace(":)", "<img src='mypic.gif' id=':)' alt='smilie' />", $string);

Hi, back again! i tryed this, and no success!

I made a function...

[code]
function modifyPost($message){
$message = $message;
$message = str_replace("\n", "<br />", $message);
$message = str_replace("fuck", "----", $message);
return $message ;
};
[/code]

and it is run just before the post is submitted to the database...

[code]
if($message){
modifyPost($message);
mysql_query("INSERT INTO chat_messages (message_id, member_id, handle, ip, timestamp, message, type) VALUES (NULL , '0', '$handle', '$ip', CURRENT_TIMESTAMP , '$message', 'post') ") or die(mysql_error()); 
};

[/code]

It should replace the "f" word with ----, but it doesnt, it runs ok and the message is added to the database, but it doesnt add a <br> for every newline in the message and it doesnt censor the word!

Why is it not working??

Thanks abydos

Your function is returning a value so you need to have something to receive that value.  Change this:

modifyPost($message);

to

$cleanMessage = modifyPost($message);

and then use $cleanMessage in your db query.

Also, check out nl2br()

You would be better off using preg_replace and generating an arary keywords (like ': P') and and an array of corresponding smileys '<img src=....'

that way you can do all replacements at once with just one line fo code (and the two arrays of course)

str_replace can also use arrays, and is faster than preg_match.

Orio.

Yay! I have it up and running good now with str_replace, so im going to leave it at that!

But thank you all so much! been a great help

Thanks Abydos
