Why does stristr not work when set to TRUE?

[gamefreak13]

Why does this work, but switching it around doesn't?

 

<?

$string = "I got the earth in my hands";

if(stristr($string, "earth") === FALSE) {
      echo "earth not found";
} else {
      echo "earth found";
}

?>

 

This does NOT work

 

<?

$string = "I got the earth in my hands";

if(stristr($string, "earth") === TRUE) {
      echo "earth found";
} else {
      echo "earth not found";
}

?>

function stristr returns string or false newer return true

Ok.. cause I have a problem here. I need to do 3 elseif's... but since it doesnt return true.. I don't think I can. Maybe I'm just getting too sleepy from all this coding today (all day long).

 

The below code works if $result['referer'] (from a mysql db) contains the stuff... but I need to do an elseif for the times that it doesnt match any of the three I have configured. Currently the ones that do not match are assigned incorrectly. For example:

 

 

http://profile.myspace.com/index.cfm?fuseaction=user.viewprofile&friendid=000000

 

should return "Profile 000000" (and it does)

 

 

http://bulletins.myspace.com/index.cfm?fuseaction=bulletin.read&authorID=000000&messageID=222222

 

should return "Bulletin 222222" (and it does)

 

 

http://messaging.myspace.com/index.cfm?fuseaction=mail.readmessage&userID=000000&type=Inbox&messageID=555555&fed=True

 

should return "Message 555555" (and it does)

 

......... however.. when the referer is something like....

 

http://www.myspace.com/someuser

 

it will assign "Bulletin ######", "Message ######", or "Profile ######"... even though it shouldn't! So I need to do an elseif to say "hey, it doesnt match the three predefined matches, so return "blah".

 

 

 

///// CHECK TO SEE IF THE REFERER IS A PROFILE VIEW
if(stristr($result['referer'], "user.viewprofile") === FALSE) {
//// DO NOTHING
} else {
preg_match('/friendid=([^&]*)/i',$result['referer'],$output);
$refererclean = "Profile ".$output[1];
}


///// CHECK TO SEE IF THE REFERER IS A BULLETIN VIEW
if(stristr($result['referer'], "bulletin.read") === FALSE) {
//// DO NOTHING
} else {
preg_match('/messageid=([^&]*)/i',$result['referer'],$output);
$refererclean = "Bulletin ".$output[1];
}


///// CHECK TO SEE IF THE REFERER IS A MESSAGE VIEW
if(stristr($result['referer'], "mail.readmessage") === FALSE) {
//// DO NOTHING
} else {
preg_match('/messageid=([^&]*)/i',$result['referer'],$output);
$refererclean = "Message ".$output[1];
}
