README

A simple class to test if a string has a profanity in it.

Checks performed

Straight matching

Checks string for profanity as it is against list of bad words. E.g. badword

Substitution

Checks string for profanity with characters substituted for each letter. E.g. bâdΨ0rd

Obscured

Checks string for profanity obscured with punctuation between. E.g. b|a|d|w|o|r|d

Doubled

Check string for profanity that has characters doubled up. E.g. bbaaddwwoorrdd

Combinations

Also works with combinations of the above. E.g. b|â|d|Ψ|0|rr|d

Installation

Install this package via composer.

php composer.phar require developer/profanity-filter 

Usage

/* default constructor */ $check = new Check(); $hasProfanity = $check->hasProfanity($badWords); $cleanWords = $check->obfuscateIfProfane($badWords); /* customized word list from file */ $check = new Check('path.to/wordlist.php'); /* customized word list from array */ $badWords = array('bad', 'words'); // or load from db $check = new Check($badWords);

Kudos

Have to mention the following project as it gave me a good foundation for the regex and a list of swear words.

Thanks to @jackcsk for his contribution, adding the ability to use a plain array instead of a file for the list of profanities. Available in version > v1.3.0.
