@Rizier123 Thanks!, i had to ask this question because i was unsuccessful in searching the solution on the web. maybe due to lack of keywords in my mind. — DeathRs, Feb 22 '15 at 09:00
FYI: If you didn't knew it already you can also search stuff on SO here: http://stackoverflow.com/search?q= Also just use keywords if you search stuff e.g. `php strpos case insensitive` — Rizier123, Feb 22 '15 at 09:02

Use stripos() instead of strpos().

int stripos ( string $main_string , string $substring [, int $offset = 0 ] )

You can use strpos function with strtolower function

$str = "how are you doing";
$ndl = 'ArE';
if (strpos(strtolower($str),strtolower($ndl))) {
    echo "true";
}else{
    echo "false";
}
