Functions

antispam_check [line 121]

string antispam_check(
 $haystack 
)

Check if a string contains abusive substrings

Note: Letting the database do the LIKE %% match is a little faster than doing in it PHP, not to mention the incredibly long overhead of preloading the list into PHP

Parameters:

$haystack:

API Tags:

Return:

blacklisted keyword found or false if no spam detected

Information Tags:

Todo:

dh> IMHO this method is too generic used! It gets used for:

comment author name
comment/message author email
comment content
message (email) content
validate_url

..and validates all this against the antispam blacklist! We should rather differentiate here more and make it pluggable!
