If the string starts at the beginning, the return is zero. If it's not there, it returns
"" (nothing, i.e. empty).
Simple way to figure between all three:
$result=strrpos($string, $needle);
if(strlen($result)){ //even is string is 0, length is still 1
//it's there, zero really means zero (or first pos'tn in this case)
}else{
//it's not there (returned empty);
}
