Sorting strings

[jc94062]

I can use the function str_replace easily enough on simple things...

$message = str_replace("swear","*****",$message);

but I can't seem to find a function that is "case-indifferent".

I've tried to use strtolower to do this but I can't get it to work without converting everything to lowercase.

Also, is there a way to count the number of times * appears in the $message string?
I thought count() might be able to do it but can't seem to work out how.

Thanks for any help

eregi_replace() is a case-insensitive
regular expression replace function.

eregi_replace("swear","*****",$message);

yup, build an array of swear, iterate through it and eventually use strlen to get the number of * to be put.

Could you give me some more info on how to do that please?
I've never yet got arrays working, always had to work around them.
Doesn't strlen just cut a string down to the first set number of characters?

Thanks, knew it was something simple :-)

don't reinvent the wheel.... this just checks to see if there is a bad word in the string... just change eregi to eregi_replace and add in som **s for this to replace the bad ones.

function bad_word ($intext) {
$check= eregi("fuc?k|[kc]unt|ar[zs]e?hole?|a[sz]?[zs]hole?|face$|pi[zs]?[zs]|@!#$|wank|pric?k|to[zs]?[sz]er|vagina|vaginer|pu[zs]?[zs][yi]|breath|mo?oke?[iy]|stink|bit?ch|bar?[sz]tar?d|s[kc]rew|bal?l[sz]|bol?lo[kc]?[ck][zs]|gonads?|idiot|mole[zs]ter|mole[sz]t|pen[iu][sz]|anu[sz]|coc?k|horrible|dirty?|filthy?|dic?k|head$|slime|kille[rd]|puke|vomit|suck|spastic|spaz|bugg?ery?|(you )|( you )|(u )|( u )|( of?f$)|( of?f )|[asz]{3,}", $intext);

if ($check) {
return TRUE;
exit;
} else { return FALSE;
}

}

?>

Nice :-)
Won't cover everything and easily circumventable, but very nice :-)
And as an added bonus, I am sure that one could have some fun completing it :-)

Yes, I'll send you a few more words an American mate came up with 🙂

But still, how do I count the number of *'s returned in the $message variable?

If someone posts a message thats comes out as * you ** or something I want to stop them posting at all :-)

I think substr_count is the function you are looking for.
