PHP Message Help

[Ancient]

I'm trying to fend off spammers in my hosting contact form and I have this idea to help stop it.

In these emails they are sending the form with keywords in it like for example: $badwords.

And I'm trying to make a code for it to search what they wrote and send and if it finds one of the $badwords that it will die();.

What I have is:

$badwords = array(array('sex', 'porn', 'unknown', 'Unkown', 'geocities', 'tripod', 'http://'));
 
if(in_array(array('sex', 'porn', 'unknown', 'Unkown', 'geocities', 'tripod', 'http://'), $badwords));

How can I hook it up to search the $message for $badwords?

try strstr() function.

elseif(stristr($message, array('unknown', 'sex', 'porn', 'some sites', 'community', 'support', 'label', 'tripod', 'geocities', 'yahoo')) === FALSE)
 {
  die("there is something bad");
 }

Doesn't work well.

It will die weither there is a $badword or not.
I have also tried it true, and stristr and they all come back with the die weither the $badword is in it or not.
It works for finding something in a subject, but the subject doesn't have an array.

elseif(!stristr($subject, 'unknown') == FALSE)
 {
  die("Subject is bad");
 }

I found out when there is more than 1 option to look for it will ignore the script or string and move on.
Also if the string is in a certain way it will always die looking in the string or not.

well... just use a for loop then

PHP Code:

for ($i = 0; $i < count ($badwords); $i++)
  {
    if (strstr ($message, $badwords[i]) != FALSE)
      {
        die ("bad words detected");
      }
  }

Thanks for the loop, runs great when searching a file extension against an extensions array list.

stristr() will work but the you have to change the condition from == to != .
Oh this is old thread, the spam bot had confused me...
