[PHP] Char1 filter

Well i was wondering if some of you guys/girls could help me with this, It filters out the but if for example i write "lol" it wont filter it. So basicly im wanting it to pick it up even if there is text after it. If you can help me i will really appreciate it.

PHP Code:

---

if(isset($_POST['motto'])) {
if($_POST['motto'] == "") {
echo "Sorry, this character isn't allowed.";
}else{ 


---

If you want me to explain it better please say.

Well it wont show the icon thing. So what i want it to do is search for a character in the line, And if its there it says "Sorry, this character isn't allowed." But for example is X is the character i want to be able to write Xlol and it to pick it up, Anyone that can help me with this il send them like

PHP Code:

---

<?php
if(isset($_POST['motto'])) {

    if(eregi("x",$_POST['motto'])) {
    
        echo "Sorry, this character isn't allowed.";
        
    }
} 
?>

It's better to escape characters though instead of forbidding them.

Also, for the love of god use indentation.
