all that code, well, geez. why not store the words in a file, space
delimited, then:
if (preg_match("/" . implode(" ", file($prof_file)) . "/i", $text)) {
print("Naughty man");
} else {
print("Well, fuck, you're curse free! Congrats...");
}
Or just store it in a string and omit the implode and file() function calls
(I'd prefer placing it in a file for easy addition of new curses)...
If you go with the other method (described by Ignacio), see the in_array()
function, which saves you the trouble of looping...
