try this; I am working on the last word... ereg replace is not finding the
REGEX "\.$" - anyone has a clue?
<?
$bannedwords = array ("dadada", "dedede", "dididi");
$string = "Dadada in this world dadaDA is not permitedadada because this
very deDede peoplededede that appears in our DIDIDi world dedede.";
$num=count($bannedwords);
/*
echo $num."<BR><BR>";
echo $string."<BR><BR>";
for($i=0;$i<$num;$i++) {
$string = eregi_replace("{$bannedwords[$i]}","[censored]",$string);
}
*/
echo $string."<BR><BR>";
// take out the damn ; . : chars on the end of the string and save for later
/*
elseif (ereg("\;$",$string)) {
ereg_replace("\;$","",$string);
$semmicolon = TRUE;
} elseif (ereg("\:$",$string)) {
ereg_replace("\:$","",$string);
$colon = TRUE;
} else {
$dot = TRUE;
$semmicolon = TRUE;
$colon = TRUE;
}
*/
$hasdot = ereg("\.$",$string);
if ($hasdot) {
ereg_replace("\.$","test",$string);
$dot = TRUE;
}
// the middle words
reset($bannedwords);
foreach ($bannedwords as $word) {
$string = eregi_replace(" {$word} "," [censored] ",$string);
}
echo $string."<BR><BR>";
// test the start word and exchange
reset($bannedwords);
foreach ($bannedwords as $word) {
$string = eregi_replace("^{$word}","[censored] ",$string);
}
echo $string."<BR><BR>";
// test the end word and exchange
reset($bannedwords);
foreach ($bannedwords as $word) {
$string = eregi_replace("{$word}$","[censored]",$string);
}
echo $string."<BR><BR>";
echo $dot."<BR>";
echo $hasdot;
?>

Subject: Re: [PHP] Help w/ regular expressions for banned words
Thanks for your help. Unfortunately, [:space:]$bannedwords[$i][:space:]
would not work, since I need to also check for the first and last word. In
a last-case scenario I could write special code for the first and last word,
but that may get ugly with bug-checking... but I've already tried
"\s+$bannedwords[$i]\s+" to no avail. I believe [:space:] is just a
substitute for \s+, right?
Yeah, I've tried \<$bannedwords[$i]\> too, unfortunately. Like I said
before, eregi_replace("a","[censored]",$string) makes a match, but
eregi_replace("\<a\>","[censored]",$string) or
eregi_replace("\ba\b","[censored]",$string) does not. Most odd.
Thanks for your help, though. Anyone else have suggestions?
