[RESOLVED] eregi_replace problem when replacing .net

[2005]

I use this function to check the text for bad words:

function filter($str)
{
$result = mysql_query( "SELECT * FROM badwords");
while( $row = mysql_fetch_array( $result) )
$str = eregi_replace($row['word'], "", $str );
return $str;
}

Table "badwords" contains also:
.com
.net
.org
.uk
etc...

Unfortunately, this function ignores "." in the beginning and if I type:

Internet
Network

this function returns:

Inte
work

Any ideas?

maybe this:

// ......
$str = eregi_replace('[.]'.$row['word'].'$', "", $str );
// ......

OR

// ......
$str = eregi_replace('[.]'.$row['word'], "", $str );
// ......

Actually, you need to escape the period, since a period in a regexp pattern means something special: match any character.

Soo... escape all periods in your "word" !

EDIT: Also, the preg_ functions are much faster than the ereg functions, so I would recommend you use those instead. For example:

$word = str_replace('.', '\\.', $row['word']);
$pattern = "/$word/i";
preg_replace($pattern, '', $str);
