For double quotes, you can just type " directly. For single quotes, since you're using them to quote the string, you'll have to use a backslash to escape them, by typing \'. (Note that this is just telling PHP to use a single quote in the string. Once it's passed to preg_match, the backslash is gone.)

BTW, your regular expression looks wrong. The $ should usually be the last character, and ^ should be the first. Unless you're trying to match multiple lines, in which case you need a m modifier at the end. For example:

preg_match('#$[a-z0-9"\']^#im',$text)
