Question

Hello all i am working on a project where i need to have find any url/links/emails, preserve the line brakes,replace the special symbol with emotions and also wordwrap. so i was wondering that if all these things are possible with only a single function or not currently i am using this function for emotions

        ':d'    =>  '<img src="smiles/lol.gif" class="icon_smile" title="Laughing :d"/>',
        ';)'    =>  '<img src="smiles/wink.png" class="icon_smile" title="Wink ;)"/>',
        ':p'    =>  '<img src="smiles/tongue.png" class="icon_smile" title="Tounge :p"/>',
        ':('    =>  '<img src="smiles/sad.png"  class="icon_smile" title="Sad face :("/>',

        ':D'   =>  '<img src="smiles/lols.gif" class="icon_smile" title="lol :D"/>',

        ':(('   =>  '<img src="smiles/cry.gif" class="icon_smile" title="crying :(("/>',
        ':X'   =>  '<img src="smiles/silent.gif" class="icon_smile" title="sealed lips :X"/>',

);
return strtr($text, $icons);
}

You could use str_replace(), array_keys() and array_values().

function emotions($text) {
    $icons = array(
        ':)'    =>  '<img src="smiles/smilee.png" class="icon_smile" title="smiling :)"/>',
        ':d'    =>  '<img src="smiles/lol.gif" class="icon_smile" title="Laughing :d"/>',
        ';)'    =>  '<img src="smiles/wink.png" class="icon_smile" title="Wink ;)"/>',
        ':p'    =>  '<img src="smiles/tongue.png" class="icon_smile" title="Tounge :p"/>',
        ':('    =>  '<img src="smiles/sad.png"  class="icon_smile" title="Sad face :("/>',
        ':o'    =>  '<img src="smiles/shock.png" class="icon_smile" title="Shocking :o"/>',
        ':|'    =>  '<img src="smiles/straight.png" class="icon_smile" title="straight :|"/>',
        '<3'   =>  '<img src="smiles/heart.png" class="heart" title="Heart <3"/>',
        '::s'   =>  '<img src="smiles/sexy.png" class="icon_smile" title="Sexy <s"/>',
        ':D'   =>  '<img src="smiles/lols.gif" class="icon_smile" title="lol :D"/>',
        ':(('   =>  '<img src="smiles/cry.gif" class="icon_smile" title="crying :(("/>',
        ':X'   =>  '<img src="smiles/silent.gif" class="icon_smile" title="sealed lips :X"/>',
        ':B'   =>  '<img src="smiles/bla.gif" style="width:29px;vertical-align:middle;" title="bla bla :B"/>',
        ':C'   =>  '<img src="smiles/coll.gif" style="width:24px;vertical-align:middle;" title="coll me :C"/>'
    );
    return str_replace(array_keys($icons), array_values($icons), $text);
}

You should use nl2br and additional functions to the result of the function. But of course you can use these functions in this function, too.
