<?

$price = "$19.99";

if(ereg("\\$[0-9]{2}\.[0-9]{2}",$price)){
	echo "this is a price";
}
else{
	echo "not a price";
}

In eregs, if you want to use the $, you have to escape it twice...the
first escape tells php to look for a variable whose name is after the
$...the second \ tells it, look for this character...
