eregi or stristr?

[factornumberone]

Hello,
im trying to exclude some bad words that users may post in my blog. Now i know there must be several ways to achieve this (i dont want to use a db), but only 2 ways come in my mind:

1.Using eregi:

if(!eregi("badword1|badword2|badword3|", $post))
{ //ok}

2. Using stristri and if statements:
   ---------------------------------------------------
   if (stristr($post ,"bad1") ||
   stristr($post ,"bad2") ||
   stristr($post ,"bad3") )
   {//bad words detected}

Which one do you think is faster? Any suggestions?
Thanks!

You can find out yourself. Use time or microtime to find out how long each of them take. You'll have to test it with a lot of bad words though, to be able to see a difference.

HTH,
