Another Way To Check For Different Characters In String

[jtmerchant]

Right now I find myself doing things like this:
if(strpos($uname,"`")!==false || strpos($uname,"~")!==false || strpos($uname,"@")!==false || strpos($uname,"$")!==false || strpos($uname,"%")!==false || strpos($uname,"^")!==false || strpos($uname,"&")!==false)
{}

This seems a bit silly; I want to check a single string for many different characters. Is there another way of doing this?

its probably best to use regular expressions, but im not much good with them. another idea would be to put all the chars your checking for into an array and loop through that. i'd put it in a function to neaten it up some too.

function check4chars($str)
	{
		$tmp = array('!','@','#','$','%','^','&','*','(',')');
		foreach ($tmp as $result) {
			if (strpos($str,$result) > 0) {
				return true;
			}
		}
		return false;
	}

Well I think strpbrk() would be simpler than screwing with regular expressions ("`~@$%^{&*=+[{]}|;:'",<.>/?"} input string instead of the long syntax.
