title: PHP Validate WKT values
body: <p>I'm trying to validate data passing between client/server for a location-based application and I can't find any way to validate WKT strings in PHP. I'd prefer not to implement it myself, not because I'm lazy or incompetent but because I'm afraid of getting it wrong because I've never dealt with WKT before. Is there any way for me to validate or must I write my own validator?</p>
