trouble with trim preg replace...

im using:
if($varCheck && trim(preg_replace("/[a-zA-Z0-9,@._]+/", "", $varCheck))) $stop = true;
if($stop=="true")
{

blah

}

how would i go abouts adding "-" ( a hyphen, -) to preg replace?

preg_replace("/[a-zA-Z0-9,@._-]+/", "", $varCheck)

lol, sweet and simple :p

preg_replace("/[a-zA-Z0-9,@._-]+/", "", $varCheck)


eh nvm :)
