Hi there, I am working on a spam filter for email forms. To improve it it would be great to compare 2 text and to find out how equal they are. Is there a function in php wich compares 2 text and returns a percentage of equality? The system allready checks for spam keywords, but there are some spam text which are verry difficult to identify. So if a person submits the same text to more people this would be another factor to check. Thank you for any help, Merlinlevenshtein()
