[SOLVED] preg_match help needed

[5ury4]

Hello everyone!

 

I need simple help with the syntax of preg_match, what I'm trying to do is to see if the user inputs any special character that is -> "@#$%^&*()+=-[]\\\';,./{}|\"

 

How should I preg_match this with a given variable say $userinput ?

 

I tried this code, but the problem with it was though it deteced # and $ but it refused to detect ! and @.

 

<?
$userinput  = "test";
if(preg_match("/\!\@\#\$\%\[\]/",$userinput)){
echo "Special Characters Found";
}
else{
echo "No SPeical character found.";
}
?>

 

Thanks in advance.

rather than including each special characters, wont it be easier to just include what you want, so the alphbets and numbers?

if(!eregi("^([a-z0-9])*$",$lname))
{echo "invalid found!";}
