Мои тестове :

$mystr = "асд";

$time_start = microtime();

$ascii = ord($mystr[0]);

for ($i=0; $i<1000000; $i++){

	$cyr = ($ascii> 191 && $ascii< 256 ) ? true : false; 

}

$elapsed = microtime_diff($time_start,microtime());

echo "Strings : .$elapsed 

";



$time_start = microtime();

$let = $mystr[0];

for ($i=0; $i<1000000; $i++){

	$cyr = preg_match("/^[А-Яа-я]/", $let); 

}

$elapsed = microtime_diff($time_start,microtime());

echo "RegEx : .$elapsed 

";





function microtime_diff($a, $b) {

   list($a_dec, $a_sec) = explode(" ", $a);

   list($b_dec, $b_sec) = explode(" ", $b);

   return $b_sec - $a_sec + $b_dec - $a_dec;

}
